Tamil Nadu will experience below-normal temperatures and intermittent rainfall until May 14 as easterly winds and active weather systems bring relief from peak summer heat, the Regional Meteorological Centre (RMC) said Friday. Twenty-two districts, including Madurai, Thanjavur, Tenkasi, and the Nilgiris, are forecast to receive isolated heavy rains with gusty winds through Sunday.
The RMC reported that maximum temperatures will drop by two to three degrees Celsius, remaining below seasonal norms across the state. On Friday, Salem recorded the highest temperature at 36.6°C, while Chennai remained cooler at 33°C, with 75% humidity due to easterly winds. An upper air cyclonic circulation over the Comorin area and a trough extending to southwest Madhya Pradesh are driving the current weather pattern.
Chennai and other coastal areas will continue to see light to moderate rainfall Saturday, with temperatures held in check by persistent sea breezes. Meteorologists noted that peak summer conditions, typically marked by strong westerlies, have not yet set in. The RMC forecasts continued rainfall in southern districts and isolated spells in northern areas over the weekend.
The weather systems are expected to sustain cooler conditions until at least May 12, after which temperatures may begin to rise. The RMC will issue its next update on Saturday, monitoring the dissipation of the cyclonic circulation and trough.
