What January feels like in Chennai
January is part of Chennai's dry season, when rain totals drop well below the wet months. Afternoons are hot, so sightseeing works best in the morning or evening. The gap between afternoon and night is small, so nights stay warm and the temperature hardly changes after dark. The air is muggy, so it feels hotter than the thermometer suggests.
