Chennai in May
Tamil Nadu, India
Skip — 38–42°C with humidity; Marina Beach shimmers, Mahabs day-trip is heat-stroke territory at midday, Pondicherry drive baking. Better window: November–February (post-monsoon) and December–January for Chennai Music Season.
May in Chennai is the year's harshest stretch. Daytime 29-39C with the last week occasionally hitting 41-42C — Madras Day usually marks the city's annual heat peak. Humidity 75 percent, sea breeze unreliable till 6pm. Pre-monsoon Mango Showers begin in the last fortnight — 30-90 minute evening squalls that drop temperatures 4-5 degrees temporarily but raise humidity to 88 percent. Heritage walking and outdoor sights collapse 10am-6pm. Marina Beach evening crowd is still substantial after 6pm — the sea breeze finally hits and locals decamp en masse — but afternoon is unusable. AC venues stay viable: Government Museum Egmore (Bronze Gallery is the standout — Nataraja, Ardhanarisvara, Krishna Govardhana bronzes from Tanjore region 9th-13th century), DakshinaChitra heritage village if you can tolerate the open-air courtyard sections after 5pm, T Nagar shopping. Hotel rates at year-low: ITC Grand Chola ₹8-11k, Taj Coromandel ₹7-10k, mid-tier business hotels ₹2.5-4k. Mango season at peak — Koyambedu wholesale market 4am-11am ₹120-350/kg for Banganapalli, Imam Pasand, Sendhura. The clean travel window opens November.
