The climate in India

Average daytime and nighttime temperatures

All climate diagrams on this page result from the collected data of 77 weather stations.
Weather stations at an altitude above 2310m have not been included.
All data correspond to the average monthly values of the last 20 years.

Back to overview: India

Climate zone: The northern parts of India are in the subtropics, the southern regions in the tropics.

The climate in India is very warm, with an annual average of 30 degrees, but has few truly tropical and sultry months. It is warm to hot all year round and invites to bathe at average water temperatures of 28 degrees. The warmest and rainiest part of the country is Rajasthan. The coldest is Himachal Pradesh. Dued to the lesser rain the best time for traveling is from November to April. The most rain days occur from from June to September.

Temperature records of the last 73 years

The hottest temperature measured from 1949 to March 2022 was reported by the Bikaner weather station. In May 2016 the record temperature of 49.5 °C was reported here. The hottest summer from July to September, based on all 54 weather stations in India below 2310 metres altitude, was recorded in 1987 with an average temperature of 28.4 °C. This average temperature will normally be measured every 4 to 6 hours, thus also including the nights. Normally, this value is 27.5 degrees Celsius.

The coldest day in these 73 years was reported by the weather station Srinagar. Here the temperature dropped to -8.8 °C in January 2021. Srinagar lies at an altitude of 1587 meters above sea level. The coldest winter (January to March) was in 1978 with an average temperature of 19.7 °C. In India, it is usual to have about 2.7 degrees more at 22.4 °C for this three-month period.

The most precipitation fell in July 1974. With 264.7 mm per day, the Cherrapunji weather station recorded the highest monthly average of the last 73 years. Incidentally, the region with the most rainfall for the whole year is around Cherrapunji. The driest region is near Bikaner.

Long-term development of temperatures from 1990 - 2021

In contrast to single record values, a long-term development cannot simply be brought about by all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would give a falsified result. If several measuring stations in particularly cold mountain or coastal regions are added in one year, the average would already decrease as a result of this alone. If a station fails during the summer or winter months, it does not provide any values and falsifies the average again. The subsequent long-term development was therefore reduced to only 4 measuring points in order to have actually comparable data over as long a period as possible.

In the years 1990 to 2021 there were only these 4 weather stations in the whole country, which reported continuous temperature values (New Delhi Safdarjung, Mumbai Colaba, Hyderabad, Machilipatnam). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was May 1998 with 33.3 °C. January 1995 was the coldest month with an average temperature of 20.5 °C.

The average annual temperature was about 26.9 °C in the years after 1990 and about 27.4 °C in the last years before 2021. It has therefore increased only slightly by about 0.6 °C over the past 32 years. This trend only applies to the selected 4 weather stations in India. A considerably more comprehensive evaluation of the global warming has been provided separately.

Data basis and methodology

The data of the individual measuring stations are based on the archives of the German Weather Service, individual values averaged and supplemented by own elements. In order to determine a representative national average, average values were first calculated for each part of the country, which were then summarized at the national level. Thus, if a disproportionate number of weather stations are located in a small area, their number does not affect the national average. There are 55 stations in India itself.In 22 cases, neighboring but nearby weather stations were also used to obtain more accurate values.
