Current conditions: 31.5°C, cloudy.
Thursday, April 30 — High of 35.4°C. Mostly cloudy with a 10% chance of rain. Humidity will make it feel closer to 38–40°C. Coastal breeze from the Bay of Bengal may offer brief relief in the evenings.
Friday, May 1 — High of 35.7°C. Clear skies and 0% rain chance — one of the drier days of the week. Peak heat expected between noon and 3 PM. A good day to plan any outdoor activity in the early morning or after sunset.
Saturday, May 2 — High of 36°C. Slight 5% chance of rain, possibly a brief pre-monsoon shower. Mostly sunny through the afternoon. Feels significantly hotter due to the coastal humidity.
Sunday, May 3 — High of 36°C. Rain chance nudges back up to 10%, with the possibility of isolated thundershowers in the evening — not unusual for this time of year as the atmosphere becomes increasingly unstable ahead of the monsoon season.
Monday, May 4 — High of 35.3°C. Back to dry conditions with 0% rain. Slightly cooler than the weekend peak, though still well above comfort levels for extended outdoor exposure.
Outlook beyond May 4: The data only extends to Monday, but based on seasonal patterns, temperatures are likely to remain in the 35–37°C band through mid-May, before the Southwest Monsoon’s approach begins pulling temperatures down slightly and dramatically increasing rainfall and humidity from late May or early June onward.
What to keep in mind: The “feels like” temperature in Chennai at this time of year is almost always 4–6°C above the actual reading due to the city’s high relative humidity (typically 60–80% in pre-monsoon weeks). That puts the real-feel for this week between 40°C and 42°C at peak afternoon hours — the kind of heat that makes outdoor exertion genuinely risky between 11 AM and 4 PM. Staying hydrated, wearing light cotton clothing, and minimising midday exposure are all strongly advisable.
