Some areas of Chennai to get light to moderate rain on November 5

After a sluggish phase post Cyclone Montha, the northeast monsoon has revived and is expected to bring heavy rainfall across Tamil Nadu till Thursday (November 6, 2025).

The State may get a break from dry, hot days as the Regional Meteorological Centre (RMC), Chennai, has forecast scattered rainfall wherein nearly 50% of weather stations in the State are likely to receive light to moderate rainfall till Friday (November 7, 2025).

On Wednesday, heavy rainfall may occur in the delta and adjoining districts, including Thanjavur and Tiruchi, and Karaikal area. Heavy rainfall is likely to cover 12 districts in the delta, north, and interior districts, including Nagapattinam, Pudukkottai, Salem, and Tiruvannamalai, on Thursday. The RMC has predicted light to moderate rainfall with thunderstorm to occur in some areas of Chennai on Wednesday.

Officials of the RMC said the wet weather would persist till November 10, helping keep the maximum temperature under control across most parts of the State. During the past 24 hours ending 8.30 a.m. on Tuesday, some parts, particularly in north Tamil Nadu, recorded light rain. Poonamallee in Chennai received 3 cm of rain, which is the highest recorded in the State on the day. Light rain continued on Tuesday.

P. Senthamarai Kannan, Director, Area Cyclone Warning Centre, RMC, Chennai, said wind convergence and an upper air cyclonic circulation that lay over west-central Bay of Bengal off Andhra Pradesh coast would influence rainfall over the State for the next few days.

“It is typical for the State to experience rainfall during the season even when no major weather system is brewing in the Bay of Bengal. We are monitoring the weather models for further development. Such dry spells are normal during clear sky days,” he said.

Tuesday’s showers also brought respite from heat in places such as Chennai. The city recorded its all-time high day temperature of 35.5 degrees Celsius for November on Monday, surpassing the previous record of 35.4 degrees Celsius experienced on November 2, 1999. A few other places, such as Erode, Nagapattinam, and Madurai, also recorded their all-time high day temperatures in early November. The maximum temperature in Chennai will hover around 32-33 degrees Celsius on Wednesday.
