Climate zone: The northern parts of India are in the subtropics, the southern regions in the tropics.
With a yearly average of 30 °C the climate in India ist warm, but has only a few really tropical and sticky months. It is warm to hot all year round and invites to bathe at average water temperatures of 28 degrees. 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 70 years
The hottest temperature measured from 1949 to December 2019 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 53 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 70 years was reported by the weather station Srinagar. Here the temperature dropped to -7.8 °C in January 2012. 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.
Long-term development of temperatures from 1990 - 2019
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 2019 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 Mai 1998 with 33.3 °C. Januar 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 27.5 °C in the last years before 2019. It has therefore increased only slightly by about 0.7 °C over the past 30 years. This trend only applies to the selected 4 weather stations in India.
