Kolkata Weather Update: Kolkata residents woke up on September 9 to a warm, cloudy morning with temperatures already hovering around 32 °C. The India Meteorological Department (IMD) has predicted a couple of brief showers in the late morning followed by light rain in the afternoon, keeping the day humid and unstable. Maximum temperatures are expected to touch 35 °C, with the evening settling into a sultry 27 °C.
While this is not unusual for the monsoon-to-autumn transition period, the persistence of high humidity has made the city’s weather uncomfortable, even when rains arrive to offer brief relief.
Air Quality: Moderate but Manageable
The air quality across Kolkata remains in the moderate range, with PM2.5 concentrations recorded at 34 µg/m³, according to real-time monitoring by IQAir. While this is an improvement compared to peak winter levels, it still exceeds the World Health Organization’s annual safe standard by nearly six times.
For most people, the current AQI does not pose severe risks. However, children, senior citizens, and people with respiratory illnesses are advised to take precautions such as limiting outdoor exposure during traffic hours or using masks in high-density areas.
The West Bengal Pollution Control Board (WBPCB) continues to monitor local levels, and officials have urged residents to avoid activities that contribute to pollution, such as open burning of waste.
Weekly Outlook: Rain and Warmth Continue
According to the IMD, Kolkata is expected to experience an active monsoon phase in the coming days.
- Tuesday: Cloudy skies, brief rain spells, with highs of 35 °C.
- Wednesday: A mix of clouds and sunshine, slightly drier, but still hot at 35 °C.
- Thursday to Saturday: A series of afternoon showers and steady rain, with highs ranging from 31 °C to 33 °C.
- Sunday and Monday: Persistent cloudiness with periods of rain, keeping temperatures below 32 °C.
The weather cycle reflects the monsoon’s last active spell over the Bay of Bengal, before it begins to retreat later in September.
Why This Weather Pattern Matters
The current conditions in Kolkata are shaped by:
- Monsoon Systems: Low-pressure formations over the Bay of Bengal are steering moist air into the city, fueling frequent showers.
- Urban Heat Islands: Kolkata’s dense urban sprawl and heavy traffic amplify heat retention, making temperatures feel higher than actual readings.
- Climate Variability: Changing rainfall distribution due to climate change is leading to longer humid phases and shorter sharp rain events, complicating city life.
Kolkata Weather Update: Impact on Daily Life
- Commuters: Expect longer travel times as sudden showers can cause waterlogging and traffic snarls in areas like Behala, Tollygunge, and EM Bypass.
- Students and Office-Goers: Morning travel may be smoother, but carry umbrellas or raincoats to avoid being caught in afternoon downpours.
- Public Health: Persistent humidity can worsen conditions like asthma, sinus infections, and skin rashes. Doctors advise residents to stay hydrated and avoid prolonged exposure to stagnant water, which is a breeding ground for mosquitoes.
Cultural and Economic Dimensions
For a city preparing for Durga Puja festivities, the weather update carries extra weight. Heavy rains in early September can disrupt pandal construction and transportation of materials. Moderate AQI, however, offers some relief for artisans working long hours outdoors.
Local vendors, particularly those selling food and textiles in open markets, brace for disruptions as showers keep customers away. On the other hand, umbrella and raincoat sales usually spike during this period.
Severe Weather Alerts
The IMD has also issued an orange alert for thunderstorms in nearby districts, including South 24 Parganas. While Kolkata is expected to see only moderate rainfall, strong winds may occur locally. Residents are advised to avoid unnecessary outdoor exposure during storms.

Long-Term Perspective
Kolkata’s weather patterns highlight the city’s vulnerability to:
- Urban Flooding: Even short, intense rain showers overwhelm drains.
- Air Pollution Spikes: Monsoon showers temporarily clear dust, but emissions remain a long-term concern.
- Climate Change: Rising global temperatures are intensifying humidity levels and altering monsoon behavior.
Sustainable urban planning—including better drainage, green cover expansion, and stricter pollution control—remains essential for Kolkata’s climate resilience.
Conclusion
Kolkata is in for a warm, humid, and rain-prone week, with moderate air quality holding steady. While residents can expect occasional relief from rain, the city’s combination of sticky heat, urban congestion, and environmental stressors continues to challenge daily life.
For citizens, the takeaway is simple: stay prepared, stay safe, and stay informed. As Durga Puja nears, both weather updates and air quality advisories will play a central role in ensuring the celebrations remain smooth and safe.
