Chennai and its surrounding KTCC belt-Kanchipuram, Tiruvallur, Chennai, and Chengalpattu-continue to experience intense early summer heat, with temperatures climbing noticeably over the past 24 hours.
Chennai Weather
The city recorded a scorching 38.8°C at around 2:30 pm, marking a clear rise from the previous day and reinforcing the ongoing hot spell across northern Tamil Nadu. Observations taken at 0830 hrs IST today indicate a maximum of around 38.0°C in Chennai, already about 2°C above normal, with warm overnight conditions offering little relief.
Chennai and northern Tamil Nadu are experiencing intense early summer heat, with temperatures around 38.8°C. While interior districts anticipate thunderstorms and possible heavy rain from May 1-4, Chennai remains hot and humid, though isolated evening showers may occur.

Humidity levels remain moderately high, contributing to uncomfortable daytime conditions. The lack of rainfall over the past 24 hours in Chennai has further intensified the heat stress, while much of coastal Tamil Nadu continues to remain dry.
However, relief may not be too far away-at least for parts of the state. The Regional Meteorological Centre has indicated favourable conditions for thunderstorm activity across the interior districts. After nearly a month of persistent heat, western, central, and southern interior regions are likely to witness evening or night-time thunderstorms, potentially bringing a welcome drop in temperatures.
Tamil Nadu Rains
A yellow alert for heavy rainfall has been issued for several districts over the next four days. On 1 May, isolated heavy showers are expected in the Nilgiris, Coimbatore, Tiruppur, Theni, Erode, and Dindigul districts. This pattern is set to expand slightly on 2 May, including Salem and Namakkal. By 3 and 4 May, rainfall activity will persist over the Nilgiris and adjoining ghat regions, along with parts of central Tamil Nadu such as Tiruchirappalli.
While Chennai itself is not under a heavy rain alert, changing atmospheric conditions could bring isolated thunderstorms or cloud build-up in the coming days, particularly during late evenings. For now, the city remains firmly under the grip of dry heat.
Across the state, temperatures have risen by 2-3°C in several locations.
Vellore recorded the highest maximum temperature at a blistering 42.4°C, highlighting the severity of the heat inland. Other notably high readings include Karur at 41.5°C, Erode at 41.4°C, and Tiruchirappalli Airport at 40.9°C. In contrast, hill stations continue to offer cooler conditions, with Udhagamandalam reporting a minimum of 12.2°C.
Rainfall activity has been scattered, with some hill and interior stations such as Coonoor, Kodaikanal, and Tiruthani recording measurable precipitation. Tiruthani, in particular, saw around 9.6 mm of rain, signalling the onset of convective activity.
In summary, Chennai residents should brace for continued hot and humid conditions in the short term, while interior Tamil Nadu prepares for a shift towards more dynamic weather, including thunderstorms and isolated heavy rain.
