Kolkata Weather Update – The City of Joy is set to experience another day of sticky discomfort as the India Meteorological Department (IMD) forecasts a combination of high humidity and scattered rainfall across various parts of the city. The rain-bearing monsoon winds, which have already marked their presence earlier this month, are intensifying again, bringing in typical July weather marked by overcast skies, passing showers, and sultry conditions.
Kolkata Weather Update: Today’s Weather Outlook
- Sky conditions: Overcast to partly cloudy
- Temperature: Expected maximum around 34°C; minimum around 27°C
- Rainfall: Light to moderate showers likely in the afternoon
- Humidity: Expected to hover between 75% to 85%
- Wind: Southerly winds at 8–15 km/h, gusting in stormy patches
Early morning conditions were relatively calm, but by late morning, low-pressure activity over the Bay of Bengal began pushing moisture-laden clouds over Kolkata’s skyline.
Rainfall and Monsoon Patterns
July is historically one of the wettest months for Kolkata, and this year has been no different. The city has already seen frequent spells of rainfall throughout the past week. According to IMD data, Kolkata has received over 150 mm of cumulative rainfall this month, inching closer to the monthly average of approximately 396 mm.
A trough stretching from Jharkhand to south Bengal is enhancing rainfall activity across the southern districts, with Kolkata among the primary impact zones. Meteorologists expect more wet spells over the weekend as monsoon circulation strengthens.
Urban Impact: Waterlogging & Traffic Concerns
Rain in Kolkata is not just a seasonal occurrence—it’s a logistical challenge. Several low-lying areas, including parts of Bhowanipore, Tollygunge, Park Circus, and EM Bypass, have experienced temporary waterlogging due to clogged drains and slow run-off.
The Kolkata Municipal Corporation (KMC) has issued an advisory, confirming that emergency response teams are on standby to tackle waterlogging and infrastructure issues. Meanwhile, the Kolkata Traffic Police has activated route diversions in key zones where water accumulation has been reported.
Commuters are advised to:
- Avoid travel during peak rain hours (between 1 PM and 4 PM)
- Use Metro services wherever possible to avoid congested roadways
- Carry rain protection (umbrellas, raincoats) and waterproof bags
Health & Lifestyle Precautions
With high humidity and rainfall, there is also an increased risk of waterborne and vector-borne diseases. Doctors are advising citizens to:
- Avoid street food and untreated water
- Use mosquito repellents and nets
- Dry clothes thoroughly to prevent fungal infections
- Stay indoors during thunderstorms and avoid standing under trees or near electric poles
Hospitals in Kolkata have reported a spike in cases of gastroenteritis, dengue, and fungal skin infections, which are common during prolonged monsoon spells.
Institutional and Administrative Response
The IMD has shared forecasts with all relevant civic and disaster management bodies. The West Bengal Disaster Management Authority has activated its monsoon alert system and is coordinating with district magistrates and municipal authorities to address any emergency situation.
Schools and colleges have been instructed to avoid conducting outdoor activities and sports drills during the afternoon due to expected rainfall.
Kolkata’s pumping stations at Ballygunge, Dhapa, and Behala are operating at full capacity to keep waterlogging under control.
Extended Forecast: What’s Ahead for the Week?
The IMD predicts:
- July 19–20 (Sat–Sun): Cloudy with scattered rain and isolated thunderstorms
- July 21 (Mon): Overcast with light rain—Martyrs’ Day rally likely to face weather disruption
- July 22–23: Moderate rainfall with occasional heavy spells
Farmers and rural dwellers in south Bengal are also advised to take protective steps for crops, especially paddy fields, which are vulnerable to flash flooding at this stage of the season.
Broader Climate Context
Kolkata’s current weather fits into broader climate patterns. The strengthening of the monsoon trough and shifts in sea surface temperatures have resulted in more intense and prolonged rains in eastern India. Climatologists have pointed to urban heat island effects and rapid urbanization as contributing to erratic rain distribution in Kolkata.
Several studies have highlighted how climate change is making monsoon seasons less predictable, with either very dry spells or intense downpours occurring over short durations.
Recommendations for Citizens
To navigate the coming days safely and comfortably:
- Plan ahead: Schedule essential travel in the morning or post-evening
- Stay updated: Follow alerts from IMD, KMC, and Kolkata Police on social media and radio
- Health hygiene: Maintain cleanliness at home to prevent breeding of mosquitoes
- Check on elderly and vulnerable: Ensure they stay hydrated and avoid exertion during peak humidity
