Chennai Weather in January

January weather

January is one of Chennai's most comfortable months. Days reach 28°C, and evenings cool to around 21°C. Humidity still sits at 77%, so a long walk can feel sticky, especially in the sun. Rain is limited to 22 mm across three days, leaving plenty of time for Marina Beach, Fort St. George and the streets around Kapaleeshwarar Temple.

The weather suits sightseeing and seaside strolls better than the wetter December. You may still want to break up a long outdoor day with a shaded stop in Mylapore. Don't expect the beach to feel cool at midday.

Festivals and crowds

Pongal, Tamil Nadu's harvest festival, usually falls in mid-January. In Chennai, you'll see festive decorations and families marking the holiday; some businesses may close or change their hours. The city's well-known Music Season also runs into January, with Carnatic music and dance performances at venues such as the Music Academy.

Travelling with kids? Pongal can be a lovely time to see local celebrations, but expect busy travel around the holiday. January is popular, so hotels can cost more than in quieter, rainier months. It's busier than the monsoon season, though December also draws visitors for the Music Season.

Tips for Chennai in January

With 8.3 hours of sun a day on average, January works well for a mix of temples, museums and beach time. Save the most exposed parts of Marina Beach for later in the day, when the sun is lower. If you're visiting Fort St. George, pair it with nearby George Town rather than trying to cover the whole city on foot.

For a Chennai-specific pause, stop in Mylapore for ven pongal, a savoury rice-and-lentil dish, before visiting Kapaleeshwarar Temple. The temple and surrounding streets give you a taste of the city's daily life, not just its festival calendar.
