Chennai

Chennai, Tamil Nadu’s coastal capital on the Bay of Bengal, is a city of 11 million where 7th-century temples stand alongside IT parks and one of the world’s longest urban beaches. The city records temperatures from 21°C (70°F) in January to 37°C (99°F) in May and receives 1,400mm of rain annually, nearly 60% from the October-to-December northeast monsoon.

Welcome to Chennai

Chennai rewards visitors who embrace its pace: mornings at a Mylapore temple watching the puja, afternoons ducking into air-conditioned filter coffee houses, evenings on Marina Beach as the sun sets over the Bay of Bengal. The city does not perform for tourists the way Delhi or Mumbai do. Its attractions are woven into daily Tamil life. The Kapaleeshwarar Temple opens at 5:30am and by 6am the first devotees are already circling the tank. The Government Museum in Egmore holds the world’s finest Chola bronze collection, largely overlooked by the crowds. The Chennai weather by month guide details exactly what to expect each month of the year.
