When is the Best Time to Visit Chennai?

The best time to visit Chennai is in January, February, and March. These months avoid the extreme heat and bulk of the rain, and temperatures hover between 21°C and 34°C. Since Chennai is not a major tourist destination, airfares and room rates are moderate through the year, except on major holidays like Diwali, Christmas, and New Year’s.

  • Best Time for Sightseeing: Like all cities in southern India, the extreme heat and monsoonal rains may affect travel plans. Unlike Mumbai and Goa, however, most rain in Chennai falls from August to December, peaking in October and November. Chennai is hot and humid all year but is worse between April and July. So, the best time for visiting is limited to January, February, and March.
  • Best Time for Weather: During the dry season from January to March, days are full of sunshine, temperatures aren’t too hot (yet), sea breezes help temper the humidity, and it may not rain for weeks. During April, May, and June, temperatures rise from warm to hot and the increased humidity is particularly notable. The monsoon that pummels Mumbai and Goa on the west coast from June to September bypasses Chennai, which receives most of its rain during the northeast monsoonal period of October to mid-December. Violent storms and cyclones are not uncommon at this time, while water-logging may also affect travel plans.
  • Best Time for Honeymoons: Mid-December to April. Avoid, if possible, the extreme heat, humidity, and monsoonal rains during the other months of the year.
  • Best Time for Nightlife: Between January and June, rain is scarce. Hence, this is the best time for partying and bar-hopping at night, even though nightlife is fairly tame in this Tamil-dominated city.
  • Best Time for Saving Money: May to November. The most popular and expensive time to visit is the cooler and drier weather, so hotel rates and airfares are lowest during the monsoon season and its lead up.

Chennai Travel Seasons

  • High Season (January to March): Day after day of warm weather, without being too hot or humid, and pleasantly mild overnight. Maybe 1-2 days of rain per month. Chennai is not a major tourist destination, so it’s not much affected by large numbers of visitors and higher hotel rates around the Christmas and New Year periods.
  • Shoulder Season (April and December): Also a good time to visit, before the high heat and humidity (May and June) and after the worst of the wet season (July to November). April can still be hot and humid, and the rain lingers in early December, but by the end of the year, the streets are clean and gardens are flourishing.
  • Low Season (May to November): Chennai is not blessed with an ideal climate for sightseeing. Heat and humidity peak in May and June in the lead up to the rains, which is at its peak during the northeast monsoon in October, November, and early December, when cyclones are common. The number of tourists reduces, so hotel rates fall, but allow time to get around because travel plans may be affected during the wet season.

Chennai Weather by Month

  • Chennai Weather in January: Second coolest month, but average daytime temperatures only drop to 30°C and remain a balmy 21°C overnight. Significant drop in rainfall to about one-fifth as much as December, but still the wettest month of the dry winter.
  • Chennai Weather in February: Daytime temperatures rise a little from the previous month and there’s a slight reduction in average rainfall. Overnight temperatures start to increase by 1-2 degrees per month until peaking in May.
  • Chennai Weather in March: Days become noticeably hotter, averaging 34°C, and overnight is a warm and humid 24°C. Driest month of the year, with barely any rain recorded.
  • Chennai Weather in April: Second-driest month, with only a couple of rainy days on average, but the heat and, especially, humidity, build to an uncomfortable level for those unused to it. Daytime averages of 36°C and 26°C overnight.
  • Chennai Weather in May: The worst month for heat and humidity as the amount of rain also increases. Thrice as wet as April – but still not that much – and the highest average daytime and overnight temperatures for the year: 38°C/28°C. Humidity is very uncomfortable, even for locals.
  • Chennai Weather in June: Some annoying rain but certainly not the sort of monsoon now flooding the streets of other cities. Still averaging 37°C during the day and 27°C overnight, while the humidity can be unbearable for many visitors.
  • Chennai Weather in July: By now, the wet season has started in earnest, alleviated by a slight decrease in temperatures, but the humidity remains very uncomfortable. Water-logging is now common in poorly-drained and low-lying areas.
  • Chennai Weather in August: Another drop in average daytime and overnight temperatures, but nothing too noticeable. Slight increase in rainfall, averaging about 132mm per month, which, by now, may disrupt travel plans a little.
  • Chennai Weather in September: The rain continues (although slightly less on average than the previous month), but the monsoon has still not arrived. Daytime and overnight temperatures remain fairly uncomfortable at about 34°C and 25°C respectively, exacerbated by the continuing humidity.
  • Chennai Weather in October: The first of the 2 wettest months, part of the northeast monsoon that doesn’t affect cities inland or along the west coast. About 270mm of rain on average, and cyclones are not uncommon, so always be alert. Average temperatures reduce a little to 32°C during the day and the humidity decreases a little.
  • Chennai Weather in November: Easily the wettest month of the year as the monsoonal rains batter the coast and damaging cyclones pass through every year or so. Expect rain every day, often for hours, flooding the streets, even outside 5-star resorts. About 360mm for the month, but still less than half of what Mumbai receives on the other coast in July.
  • Chennai Weather in December: Significant changes starting with average day/night temperatures at their lowest for the year: 29°C/21°C. The rain tapers off in the second half of the month to a total of nearly one-third as much as November. Cyclones are still possible; in fact, a very severe cyclonic storm called Vardah hit Chennai in early December of 2016, causing extensive damage.
