India Weather Data
My blog statistics have revealed that many viewers have reached my site in search of weather data for Indian stations. The best way to get this information is to visit the official web site of the India Meteorological Department at www.imd.gov.in and then choose from a variety of links available on the home page. Under “City Weather” stationwise observations of maximum temperature, minimum temperature and 24-hour rainfall, departures from normal, times of sunrise, sunset, moonrise and moonset, and the local forecast, would be displayed. The IMD web site offers online plenty of information of climatological as well as current interest.

Sir, I’ve been able to convert the precipitation and temperature data from IMD to stata format. However, the time variable when formatted to %td is showing 2059 instead of the real year 2000 and 2080 for the year 2021. What can be done to rectify this?
Also for the years 2005-2010, I’m not able to format the time at all.. The lapsed time since 1960 jan1 which is what stata uses is not correct when I convert data from Netcdf format to dta. What can be done?
Sep 12, 2022 @ 10:04:06
Dear Sarah,
Thanks for visiting my site.
I am sorry to know that you have encountered problems while converting data that you have apparently got from IMD. I suggest that you contact Dr O P Sreejith of IMD Pune and seek his help. His email id’s are sreejith.op@gmail.com and op.sreejith@imd.gov.in. You may give my reference if you like.

Prof Kelkar,
I have a few questions and am hopeful that you can help me with.
1. For creation of global data sets as inputs to WMO for NWP, India shares what kind of information? Are they by and large coming from their Synoptic met stations?
2. How effective are the data collection from the AWS?. Is this data also shared with WMO?
3. The data from AWS are different in terms of averaging periods, frequency (how many data points per day etc). A paper from Mr.Ranalkar says the anemometers used in AWS have an accuracyof 1.2 m/s. I just hope it is a typo.
4. Data recovery rates from AWS, how good is it in general?
5. Is ‘Nowcasting’ more of a qualitative analysis or can one take the results as sacrosanct? I mean, what may be uncertainties associated with the numbers?
6. What kind of quantitative validation exists for the results obtained?
7. Who are the experts within the country apart from you on these aspects? Hope to hear from you.
Many questions I know, you are one Master who will know all the answers correctly. Hope I am no t intruding.

Dear Vaithi,
Agromet data is usually recorded for specific purposes or in a research mode and is therefore not routinely published on web sites. Daily weather data can be found on sites like tutiempo.in or aws.imd.gov.in. You have not revealed where you are working, but it will be helpful to get in touch with scientists working at the agricultural university in Anand. They may have more information.

Sir
Can I get yearly cloud cover data data for a pedicure location for which longitude-latitude is known. Actually we want to decide about installing q solar pump in an interior area. So we want to know whether the pump will work during rainy season or winter or not.
Sep 27, 2018 @ 11:44:23
Dear Arup,
Thank you for visiting my site. Of course, during the rainy season, the sky will be much more cloudy than in other months. But instead of taking a roundabout way of first getting cloud cover data and then estimating solar radiation, I suggest that you work with solar radiation data directly. You may like to visit the sites below on which solar data is available for whole of India in map form.
https://mnre.gov.in/india-solar-resource-maps
https://www.nrel.gov/international/ra_india.html
From the maps you can interpolate for your location.
Hope this information is helpful to you.

I can provide the Longitude and latitude of the site.
Oct 10, 2017 @ 23:54:20
Dear Ashok,
The incoming solar radiation in a clear sky situation can be computed from the sun-earth geometry. There are algorithms available om the internet which you can download and use for this purpose. If your AWS makes cloudiness measurements, you can also use the cloud data and make a reasonable assessment of the solar radiation.
Alternatively, you can compare your measurements with those of nearby AWS stations or IMD radiation stations.

Sir,
I am a technical staff working under Pondicherry University. I am developing a website where I want to autoload weather information on daily basis related to Pondicherry area. I could see weather information like temperature today and for next few days at imd.gov.in and imdaws.com websites. If want to access those data by means of program like API integration, is there anyway to make it.???
Currently I am displaying data based following websites http://www.yr.no/place/India/Pondicherry/Puducherry/ and
https://www.powr.io/plugins/weather
and our website is http://new.bicpu.edu.in

Dear Malan,
Thank you for your comment. I visited your web site and saw the weather information that you display. Regarding your plans to link it with IMD’s data, I suggest that you get in touch with IMD, since there could be copyright issues. You may send an email to webadmin.imd@imd.gov.in or fill up the feedback form on the IMD web site.
I also suggest that you contact Mr A D Tathe of IMD Nagpur who knows the intricacies of the IMD web site design. His email id is adtathe.imd@gmail.com

I want the Sun Altitude & Azimuth angles in a tabular form for the representative dates (say Jun 22, Sep 21 etc).
I will use this data to teach the students how to make a Sun Path Diagram.
Currently, the students are relying on the Internet and downloading “Ready Made Diagrams” without understanding the concept.

But the plans fell short because I could not locate the data.

Q: Does IMD site have this data?

Sir, the world weather online provides the data for temperatures of almost all places (because the IMD has data only for selected stations. This data however is perhaps based on the andriod version (some projections or similar, without the actual measurements). Infact I require the daily temperature of 5 different locations at varying altitudes in the darjeeling hills for the year 2015 where there are no monitoring stations. I however measured the outdoor max and min temperature and RH for 1 locations in the year 2015. Using it I tried interpolate the others as per the Lapse Rate.
Is my approach acceptable for a research purpose?
Jun 21, 2016 @ 07:33:00
Dear Samar,
No, the lapse rate is related to the free atmosphere. Temperature at different heights in the Darjeeling area may be governed by several local factors like winds, sunshine, clouds, etc. which you do not know.
Best wishes for your research.

Dear Manish,
I do not know your background and your domain name is Russian so I do not know where you are. But I think you should try a more elegant method of doing this analysis. I suggest that you get only the daily maximum and minimum temperatures (which are easily available) and fit a diurnal variation curve and then just read off the threshold values or get the respective areas under the curve.
Otherwise you will have to ask IMD to supply you the hourly data.

Dear Rukmini,
Weather data are recorded the world over at the same time so that they can be plotted on a chart. It is a standard practice to record observations at 00 GMt and 12 GMT (or 5:30 and 17:30 IST).
In India the times 08:30 and 17:30 IST are convenient because of daylight and also because minimum and maximum temperatures can be read from the thermometers.

b) I tried to cross check the data for two websites on google………..at one particular sunset time (time given by one website), the sky was blue and at another time given by another site 4 mins later, the sky had turned red. Is the second one more authentic? (I was not able to see the sun but only the sky from my window).

The most authentic site is http://www.packolkata.gov.in. There you can download the sunrise and sunset times for Kharagpur.

Aug 26, 2014 @ 10:30:48
Dear Nikita,
How do you define weather derivatives?
R R Kelkar
Aug 27, 2014 @ 09:05:20
An instrument used by companies to hedge against the risk of weather-related losses. The investor who sells a weather derivative agrees to bear this risk for a premium. If nothing happens, the investor makes a profit. However, if the weather turns bad, then the company who buys the derivative claims the agreed amount.
Aug 27, 2014 @ 09:14:51
Thanks, Nikita. It should now be obvious to you that no one is going to compute such statistics and offer them on a web site for your free download.
Good luck to you for your project.

Is there a correlation between presence of windmills and the precipitation levels in that area? There are some reports from Texas and China which state that the rainfall decreases in the downwind areas. On my recent visit to Udumalpet in TN ,which has significant windmill deployment, the locals were mentioning lesser rainfall. Has anyone done this research in India? Where can we get the data for a period of 10 years to do studies in all areas having significant windmill deployment?

None. My ancestral village happens to be in Udumalpet area. I visited this place for the first time last year. Have been hearing it from the residents of that place. Since I heard it from many people got interested in this question.
Jul 14, 2014 @ 12:14:48
Dear Sreedharan,
Thanks for the clarification.
There was a similar scare when windmills were installed in south Maharashtra a decade back. But a scientific study was carried out and it dispelled all doubts. I do not have a copy of the report.
So I feel that you need not worry. You could still carry out your own independent study but that will be like reinventing the wheel.

Oct 23, 2013 @ 23:49:43
Dear Anju,
If you want a “reliable” source, then that is the India Meteorological Department. You can ask for the data from their National Data Centre at Pune.

Respected Sir,
I am in need for Daily Wind Rose charts (or sufficient data to formulate them) for KARWAR (south of Goa) for last two years.
I am in touch with NIO for Wave Data.
I have also contacted IMD,
But can you suggest any other source to acquire such information.
I need this data as I have plans to develop a system to harness Energy from Ocean.

Dear Dr Kundapur,
Thanks for your comment.
Wind roses for some stations in India are available online at http://www.imdagrimet.gov.in/search/node/wind%20rose
However, IMD is the only source of long term data on winds. So please contact them. Mangalore has an airport, so you should be able to get the wind rose for Mangalore at least. See this site http://www.windfinder.com/windstats/windstatistic_mangalore_bajpe_airport.htm
IMD has published an atlas of wind roses which you can get on payment. See http://www.imd.gov.in/doc/advt.pdf

Thank you so much for your immediate response, very kind of you.
I have visited IMD site and also learn about the publication, as I am in need of data just for one or two places, may be I will hunt for the book at local colleges.
The of the other 2 sites you have mention, one is based at Germany, they may not have detailed charts, in any case will contact them.
The first one has data for Bangalore, but not Mangalore or Karwar, will contact them in any case.
Sir, I request you to visit my site http://www.kapalishakti.com, I have launched the company to promote the system to harness Ocean energy, but I am yet to get financial support. (I would be happy if you could please find time to visit my site on Solar cookers as well, at http://www.solcooker.net)

Respected Sir,
I want to collect cloud cover data for Kharagpur, West Bengal, India. Different websites like World Weather Online, Intellicast and Weather 2 provide different figures for the same hour and date. I do not know which one to follow. As far as my understanding goes these data are modelled and not actual observations. Am I correct? Could you please suggest me some guideline about it? Also, if I were to collect it myself, what method can I follow? Can I analyse sky photographs and do it on my own?
Thanking you for your kind advise
With Best Regards
Aparna
Sep 28, 2013 @ 05:42:55
Dear Aparna,
The problem is that extracting cloud cover information from satellite images is difficult. Because the satellite sees clouds from above, which is the opposite of an observer’s viewpoint. The same is the problem with cloud data extracted from models.
So what you really need is actual observations of the sky made by an observer. The cloud amount in oktas, the type of cloud, the height of the base, can only be recorded by an observer looking skyward.
Since you are at IITKGP, please find out if any of your departments has already collected such data. If not, then discuss your data needs with IMD’s Regional Meteorological Centre at Alipore, Kolkata.
It is also important for you to decide with what accuracy you need the data. That will make your search easy.
Best wishes,

Dear sir,
Sir, i would like to express my hearty gratitude for responding to my query.
i am interested in studying continuous long term variability of cloud cover data over Lakshadweep sea and for that i am not sure whether I can use the ground station data available from Minicoy island alone to detail the cloud coverage for entire Lakshadweep sea.
Sir, Regarding the Satellite imagery, I have tried with MODIS cloud fraction data and was not satisfactory because of its coarse spatial resolution. in this regard, i request you to provide me a data source to obtain quality satellite images.
Regards,
Ranith.R
Aug 03, 2013 @ 13:40:55
Dear Ranith,
You have defined your problem quite vaguely. When you say MODIS is ‘coarse’ resolution, what is the resolution that you are going to work with? And when you say ‘long term’ how many years of satellite data would you need? And what is a ‘quality’ satellite image? If you don’t like MODIS you can use Kalpana data, for which you will have to ask IMD.

The Konkan Strip has been heating up for the past few days, Ratnagiri recording in the range of 38-39 degrees, Mumbai( S.crz) have touched 40 degrees today. On contrary interior regions like Madhya Maharashtra, Vidarbha have been near about normal( 33-36 range). Clearly the sea breeze( which brings a cooling effect with added humidity) in konkan is simply not setting in in-time, i.e. by late afternoon and temperatures are shooting up like anything. Any reason for this abnormal phenomenon? Is the dry North Easterly land breeze too strong over Konkan or anything else?

Thank you for your reply Sir, Btw I am a weather enthusiast and in no way related to the world of meteorology either academically or professionally. I have keenly followed the vagaries of weather for long especially over the sub-continent and weather phenomenons excite me a lot. I have another query regarding the frequency of Western Disturbances during winters. I have observed that this year WDs have been quiet frequent and strong enough to affect not only NW India but the entire stretch of Indo Gangetic plains, MP, Gujarat, Chattisgarh and Orissa. Is there any particular global phenomenon behind this and if this trend continues should there be a change in cropping patterns( for your information untimely rains/hailstorms on 11th Feb in North Maharashtra and South MP have caused widespread damage to crops).

Mar 02, 2013 @ 12:28:43
Dear Arindam,
Data recorded at two different sites will never be identical. But you can substitute one for the other depending on your application, which you have not revealed to me. Rainfall is highly variable with regard to space and time, but temperature and wind do not differ much if the topography is the same. So you can decide accordingly.

Dear Sir,
Greetings.
I am Surendhiran (Final year B.E. EEE) from Coimbatore Institute of Technology. As a part our project we are developing mathematical models for calculating solar irradiance for major cities in TamilNadu. As you may be aware of, last week Tamilnadu Government has announced its “Solar energy policy” in which there are solar irradiance data for each location in Tamilnadu based on the NASA climatic data collected during 2002-2008 (hour by hour). As per that data, Coimbatore has average global solar radiation of 5.290 kWhr/m2/day (455.17 calories/m2/day). But as per the data we collected from TamilNadu Agriculture University’s agroclimatic centre for the year 2008-2012, the average solar radiation of Coimbatore was around 4.31 kWhr/m2/day (385.177 calories/m2/day). Despite the difference in the timings of recording, these data seems to be deviating significantly from each other. Here I request you to comment on this issue because your view will be helpful in our modelling. I would like to know which data is likely to be more accurate.

Dear Mukesh,
I suggest that you visit the Agriculture Ministry’s web site. The following pages may be of help tp you:
Click to access RAJ7-Sikar-30-06-2011.pdf
Click to access RAJ1-Jaipur%203.2.2011.pdf
The best way of doing this type of research is by working in the fields. But these days researchers prefer to sit on a computer and expect all the data to be displayed on their screens. This is possible with meteorological data but agriculltural data bases are not as well-organised. So you will experience difficulty.

respected sir,
Thank you very much for your support ,the information provided definitely going to help in my research.
Sir there is one more request for you,I want want to remind you that my research is both analytical and based on the historical data ,we are going to predict the crop production for a particular region with the help of the historical data related to the the crop production (MAIN FACTOR) and the factors which may affect the crop during any season ,for example temperature,humidity ,rainfall,soil fertility for that region .So sir I need the information from where to get the data (specially the soil fertility and the crop production data ).
Sir also suggest me from where to get the information that how the factors mentioned above affect the crop production simultaneously ,as we have to generate the rules out of this information that how and how much the factors affect the production.For example we can generate the rule like this: IF the temperature=normal and humidity is normal,rainfall= average THEN production=good.Please provide me any source(any link or research paper”how temperature affect the crop production ” and “how the humidity affect the production and “upto what extend the rainfall is usefull for the crop production(wheat and bajra) “) to get necessary information to create the knowledge base for the rule generation step.
Thanking you

Dear Sir,
Thanks for spending me your valuable time. I am terribly sorry if this comment comes twice because I had some problem with my connectivity and I not sure that my previous comment was posted or not(hence I repeat this again). Wind direction is not my concern as turbine head is dynamic to changes in wind direction. I think I may need to clarify my first query. The data for wind speed I have, was taken at 8.30amevery day and it is the average wind speed for the whole day. But average wind speed for the whole day(average dinural wind speed) is what I need. Is there anyway to calculate the average wind speed with the data I have?
Aug 26, 2012 @ 12:38:07
Dear Surendhiran,
Of all weather parameters, wind speed is the most variable. So, it cannot be extrapolated or interpolated. If you really want average for the day then you will need several observations over the 24 hour period and then take their mean.
If you want averages directly you may see this link
http://www.tutiempo.net/en/Climate/Coimbatore_Peelamedu/2011/433210.htm
Here you will get wind data on daily, monthly and annual scales for Coimbatore, but I am not sure about the site’s authenticity.
Best wishes,

Dear Sir,
First of all I am much impressed on your knowledge in climatology. I am Surendhiran.A.V , pursuing my B.E. EEE from coimbatore institute of technology. I am doing my project on solar and wind energy hybrid systems. I have wind speed data taken at 8.30 am for every day for the past 4 years. Now I have to calculate the mean wind speed of coimbatore throughtout the year so that I can optimise my wind turbine design. I want to know is there any empirical formula for the calculation for mean wind speed from the data I have or there is any website which provides accurate mean speed data
Aug 25, 2012 @ 00:22:45
Dear Surendhiran,
Wind is a vector quantity, so if you have both wind speed and direction data, you should derive a vector mean. This is done by breaking every wind value into a u- and v-component, i.e. easterly and westerly component, then averaging the u- and v-components and finally combining back the average u- and v-components back to the average wind vector.
However, if you have only wind speed data, or if you are not interested in wind direction, then you can just average it over the 4 year period and get an arithmetic mean of wind speed.

This is Kousik from west bengal,India.From Last few days I am searching for some graphic data showing 24 hrs of temperature variation in graph starting from 00 hrs to 24 hrs for the most hottest day and place for India for the year 2012.I get some data from IMD as well as other sites but they don’t fulfill my requirement and I am now puzzled how I continue my R&D because this is the assingnment given to me by my Project Manager,basically this data is required to made a prototype(TRACTION CONVERTER UNIT FOR INDIAN RAILWAYS LOCOMOTIVES) and this data specifies the maximum operational temperature during day time in India for the locomotive.
Hope I will get the reply and the much needed help from your side.
Thanking You,

Kousik
Apr 27, 2012 @ 07:25:01
Dear Kousik,
The best way to overcome your difficulty is to simulate a diurnal temperature graph. The maximum temperature is usually observed around 1430 hours and the minimum around 0730 hours local time. Using an extreme value of say 50 deg C for the maximum and a minimum of say 20 deg C you can yourself construct a smooth diurnal curve.

There are many internet sites such as http://www.fi.edu/weather/todo/todo.html which tell you how to construct simple weather instruments. However, much depends on what you want to do with them. If it is just your hobby, you can go ahead, but do not expect accurate data from such makeshift tools.

Well, you cannot construct a wind rose if there is no wind data! But you have the following options:
(1) Instead of Ooty you can choose another station (for your case study) for which data is available
(2) Get data for stations around Ooty and interpolate
(3) Get data for a neighbouring station and use it for Ooty with some approximations

Hello ,
I am doing a simulation for a project which involves air conditioning and measuring the power consumed by it due to the temperature difference between the ambient and the internal heat generated . It would be helpful if daily hourly temperatures of few cities with diverse temperatures could be located .

Hello Prof ,
I appreciate the quick response on the data link . The data presented at the website has different hyperlinks for every hour and shows the current temperatures for all the stations . Eventhough this might be very close to what i am looking for , if there is a view by which i could access the historical hourly data for stations in the same page it would be very helpful .
Thanks ,

hello sir,
I am doing project on improving IMD.So I just want to know why forecasts made by IMD are not as accurate as forecasts made by some foreign countries like US,UK. What are the technical as well as management level problem faced by IMD during distribution of information or detection phase, some inherent technical problems?
I hope you will reply to this and help to guide this during the study
Jul 20, 2011 @ 00:52:09
Dear Amit,
Thanks for your comment. I suggest that before proceeding on your project about improving others, you may do a little introspection into your own lifestyle, thinking, relationships, work, education, hobbies, interests and so on. You will find a lot of scope for change. Embark upon a self-improvement project and if you see good results, let me know.

Dear Sir,
I require daily temperature records (min, max, mean) for New Delhi for the year 2008 for a research project on estimating economic activity in India.
I’m also using U.S. MODIS ‘Land Surface Temperature and Emissivity’ data for 2008 from https://lpdaac.usgs.gov
If you could also advice me on whether these two temperature measurements are even comparable from the point of view of the technology used to capture each, that’ll be great help.
Kindly help.
Regards.
Apr 21, 2011 @ 11:20:51
Dear Mayuri,
Please visit the IMD web site at http://www.imd.gov.in/section/climate/climatescroll.htm for Delhi data.
Satellite retrievals are not directly comparable with measurements made on ground, primarily because the surface emissivity is not precisely known, unlike over the sea where it can be assumed to be 100 %.

Dear Sir,
I’ve been looking for snow precipitation data for Indian cities/districts for any one year, without much success. The IMD website and most other portals give rainfall stats. But I cant find snowfall data anywhere on the web.
The final purpose is to know which districts in India are permanently snow-covered or at least have a snow cover for most of the year.
Thanks,

Jun 22, 2011 @ 12:18:20
Sir,
I’m working on a paper relating satellite observed data with economic activity, like I mentioned before. Its been observed that snow-covered areas reflect more light which is captured in the satellite images, and hence need to be corrected for, before any economic estimations can be done.
I’m getting good results for the rest of India, except for the north-eastern states and mountain states of India. Therefore, I need to investigate if it is the effect of snow that is leading to these errors.
Jun 22, 2011 @ 15:31:01
Dear Mayuri,
I am still trying to understand what you are doing. Are you a student or a teacher or a professional research worker at an institution? Where are you working and in which country? Is your expertise in economics or in science? Have you published any papers so far and can you give me the references?

Sep 04, 2010 @ 12:18:28
Dear Asis,
I suggest that you visit the Regional Meteorological Centre, IMD, Alipore, Kolkata, and discuss your problem with the scientists there, if it is possible for you to do so. The India Meteorological Department, Pune, has very recently brought out a publication entitled “Solar Radiant Energy over India” (876 pp.). You may like to acquire it for yourself or consult it in the IMD Alipore library. It may contain the information that you are looking for.
I do not think that it is a good idea to try to derive bright sunshine hours from temperature as the relationship between them is not straightforward. Sunshine is more a function of cloudiness than temperature.
Wishing you good luck in your project,
Sincerely,
Kelkar

Since you are studying in the College of Engineering Pune, and since you are in such a great hurry, why don’t you just walk across to the IMD Office at Pune (Simla Office). Meet some one at the National Data Centre (NDC) or go the Library and I am sure you will get what you want.
