The India Meteorological Department (IMD) has forecast normal to above-normal rainfall during November for most parts of the country, except Tamil Nadu, Uttarakhand, Himachal Pradesh, Jammu & Kashmir and parts of Arunachal Pradesh.
Due to the likely continuing rainfall activity, the day temperatures in the month ahead are expected to remain below normal, making the days cooler, according to the forecast. However, due to clouding and overcast sky conditions, the minimum temperatures could remain above normal, making nights warmer than usual for November, the Met department said.
Rainfall during the winter months, associated with the northeast monsoon, is likely to be normal along the south peninsular India, the IMD said. This monsoon is the chief rainy season for Tamil Nadu.
“Tamil Nadu, Karaikal, Puducherry, coastal Andhra Pradesh, Yanam, Rayalaseema, Kerala, Mahe and south interior Karnataka will receive normal rainfall during November, which can range 77-123% of the Long Period Average,” the IMD said Friday while releasing the November temperature and rainfall outlook for the country.
October, across the country, ended as one of the wettest months in recent years. The deep depression over eastern India during early October and cyclone Montha towards month-end were two major contributors for such enhanced rainfall.
Last month saw two cyclones, Shakthi and Montha, developing in the North Indian Ocean basin comprising the Bay of Bengal and the Arabian Sea. During January-September, this basin had not reported development of any cyclones.
“But 2025 is not an exception. Previously, no cyclonic storms developing during January-September were reported in 1938, 1949, 1980, 1983, 1984, 1986, 1988, 1993, 1995, 2011 and 2012,” said Mrutyunjay Mohapatra, director general, IMD.

Exceptionally heavy rainfall (about 350mm in 24 hours) associated with cyclone Montha was recorded over coastal Andhra Pradesh, Yanam, Odisha, Rayalaseema, Telangana and Gangetic West Bengal during October 28-30. The all-India average rainfall during October, at 112.2mm, was nearly 50% surplus, making it the second wettest October since 2001 and the 16th since 1901.
The Northwest India region, where the monsoon withdraws completely by October, however, reported a surplus of 160mm last month – the 3rd highest since 2001 and the 10th highest since 1901, the IMD said.
