Chennai in December
Tamil Nadu, India
Go in December—peak season with ideal weather (22–30°C), Margazhi music season fills the city, and Marina becomes fully accessible by evening.
Peak crowds
December is one of Chennai's busiest months. The score rates conditions — weather, access, value — not how many people you'll share them with. Busiest Nov–Feb with winter tourism and cool weather; Apr–Jun peak heat sees lowest crowds.
December in Chennai is the operational peak — Margazhi music season pulls visitors from across the country and the diaspora returns for the family-and-concert calendar. The Tamil month Margazhi opens December 15 — 1000+ Carnatic concerts across 30 sabhas with Music Academy (TT Krishna Road, season anchor since 1928), Krishna Gana Sabha, Narada Gana Sabha, Mylapore Fine Arts Club holding marquee schedules. Sabha canteens (Music Academy's Kalyana Bhavan, the Mylapore filter-coffee stops Rayar's Mess and Karpagambal Mess) become unofficial green-rooms. Most sabha tickets ₹100-1500; season passes ₹3000-8000. Karthigai Deepam (December 4, 2026) brings Tiruvannamalai cross-traffic. NE monsoon tail drops 200-250mm across 8-10 wet days — Marina access closes intermittently on cyclone-watch days. Daytime 22-29C, humidity 75 percent. Hotel rates at year-peak: ITC Grand Chola ₹15-22k, Taj Coromandel ₹14-20k, mid-tier business hotels ₹4-7k. Lock sabha-adjacent accommodation in Mylapore 4-6 weeks ahead. Cyclone watch holds through December 20 historically.
