Kolkata Weather in April 2025 : A Fiery Mix of Heat, Humidity & Heritage

🌤️Introduction

Kolkata weather in April 2025 kicks off the summer season with blazing heat, sticky humidity, and sudden bursts of thunderstorms. But beyond the sizzling sun, the city buzzes with cultural energy—think festivals, street food, and endless exploration. Whether you’re a local planning your week or a traveler heading east, knowing the weather forecast can make your April smoother and more enjoyable.

🌡️ Temperature Trends: Summer Is Here!

April is one of Kolkata’s hottest months, second only to May. Daytime temperatures soar to an average of 36°C (96°F), while nighttime offers some comfort with lows around 25°C (76°F). Historical trends show the mercury hovering around 30°C (86°F), but don’t be surprised if it spikes to 40°C on particularly scorching days.

What makes it tougher? Humidity. With levels ranging from 55% to 85%, it often feels hotter than it actually is. The city’s coastal location adds to the mix—think warm breezes with a heavy, tropical punch.

🌧️ Rain & Thunderstorms: Enter Kalbaisakhi Season

April also marks the arrival of the dramatic Kalbaisakhi storms—Kolkata’s signature pre-monsoon thunderstorms. Expect 3 to 8 rainy days, with total rainfall reaching around 59mm. These storms hit suddenly, often in the late afternoon or evening, with gusty winds, thunder, lightning, and heavy downpours.

For first-timers, Kalbaisakhi is an unforgettable experience. It’s nature’s sudden mood swing—hot, dry skies giving way to booming clouds and lashing rain within minutes.
