Kolkata Weather in May

May feels heavy

May in Kolkata is hot, sticky and often stormy. Daytime highs reach 37°C, and nights stay warm at 27°C. Rain falls on 18 days, often in sharp showers, with humid air lingering afterwards. The comfort rating is poor, so long walks through Maidan or across north Kolkata can feel draining.

You'll get more from indoor sights such as the Indian Museum or Victoria Memorial during the hottest part of the day. Save a short visit to Kumartuli's sculptors' workshops for a cooler spell, and expect sudden rain to disrupt plans. The city gets more rain in June, but May already brings plenty.

Festivals and quiet streets

Rabindra Jayanti, celebrating poet Rabindranath Tagore's birth, is marked in May with songs and cultural programmes. Its date shifts each year. Buddha Purnima may also fall in May, bringing a public holiday and local observances.

If you hate crowds, May can be a calmer time for sightseeing than the busy December and January peak. You'll generally find fewer visitors and lower hotel prices than in those popular months. The trade-off is the heat and rain, which can make an outdoor-heavy trip uncomfortable.

Make the day work

Keep plans flexible around sudden showers. For a practical break from the heat, take the Kolkata Metro to Esplanade, then visit the Indian Museum nearby instead of walking across the city. Its galleries offer a welcome indoor stop before you head out again.

Travelling with kids? Keep a visit to the Maidan brief, and pick an indoor stop nearby for the sticky afternoon. If a Kalbaishakhi storm—a sudden pre-monsoon thunderstorm—rolls in, pause under shelter rather than trying to cross open ground. Check local timings for May's cultural programmes, since dates vary from year to year.
