As the monsoon deepens its grip on eastern India, Kolkata Monsoon 2025 enters a defining phase with a week marked by steady showers, fluctuating temperatures, and rising humidity. While the rain has brought relief from the punishing heat of May and early June, it has also led to waterlogging, health concerns, and renewed worries about long-term climate trends.

Relief from Heat, but High Humidity Persists
While the rainfall has brought down the mercury marginally, humidity has remained a pressing concern. Pedestrians, traffic constables, and outdoor workers continue to grapple with a “wet heat” phenomenon, where the sweat-induced discomfort becomes overwhelming despite moderate temperatures.
“The rain is helpful, but it’s not cool enough. I feel sticky all day,” said Moumita Dutta, a college student from Jadavpur.
Impact on City Life
1. Traffic and Public Transport
- Waterlogging in key areas like Behala, Tollygunge, and Park Circus.
- Metro ridership increased by 18% as commuters avoid road snarls.
- Flight delays at Kolkata Airport due to low visibility.
2. Health Concerns
- Rise in mosquito-borne diseases: local hospitals report higher dengue and malaria cases.
- Skin infections and fungal allergies on the rise due to sweat retention.
- Doctors urge people to wear cotton clothes and stay hydrated.
3. Drainage and Infrastructure
- The Kolkata Municipal Corporation (KMC) reports 142 pump failures in the last week.
- Emergency desilting underway in Salt Lake, Rashbehari, and Ultadanga.
- KMC helplines flooded with daily complaints of waterlogging and overflowing manholes.
Rain: A Boon for the Environment
Despite urban inconveniences, environmentalists are cautiously optimistic. The city’s depleted ponds and aquifers are slowly refilling, and the return of migratory birds to Rabindra Sarobar has been noted.
Key benefits:
- Replenishment of groundwater in South 24 Parganas
- Blooming of monsoon flora in the Maidan and Botanical Gardens
- Cooling of air quality index (AQI) from 162 (moderate) to 84 (satisfactory)
Farmers and Monsoon Dependency
Beyond the city, the rains have been a lifeline for paddy cultivators in Bengal’s rural belts. Districts like Howrah, Hooghly, and Murshidabad report successful sowing thanks to early monsoon moisture.
A spokesperson from the West Bengal Agriculture Department noted:
“The timely arrival of monsoon ensures that aman paddy cultivation stays on track. Farmers have resumed sowing, and water reservoirs are filling steadily.”

Climate Change in the Backdrop
Climatologists warn that while this week’s rainfall may seem like a return to “normal,” the larger picture remains worrying:
- Kolkata’s monsoon has shifted by 6–8 days over the last two decades
- Rainfall is more concentrated in fewer, heavier spells
- Urban flooding risks are increasing due to inadequate drainage and concretization
According to a recent IMD report, 2025 is trending as the 4th warmest year globally so far, underscoring how even rainfall may not offset global warming’s impacts.

“I love the monsoon, but I’m scared of stepping out in knee-deep water,”
— Ratan Saha, Behala resident.
“This is the best time to enjoy tea and pakoras, but our lane is like a river after 10 minutes of rain,”
— Arpita Roy, homemaker, Lake Town.

— Bidyut Mondal, delivery executive.
