Kolkata residents woke up to a refreshingly crisp and sunny morning on Friday, December 5, 2025, a welcome change following a day of severely polluted air. The city's weather has taken a pleasant turn, offering ideal conditions for outdoor plans, though caution is advised due to lingering pollutants from the previous day.
December 5 Weather: A Detailed Look
The day began with a cool minimum temperature of 16°C, promising a comfortable start. As the day progresses, the mercury is expected to climb to a warm 27.7°C by the late afternoon. The skies are completely clear, with no forecast of rain, making it perfect for stepping out.
Adding to the comfort are gentle winds blowing at a maximum speed of 16.2 kilometers per hour and moderate humidity levels of 38 percent. This combination ensures the air feels neither too dry nor uncomfortably sticky. The evening is expected to cool down gradually, setting a serene scene for a walk or an open-air dinner.
Recovering from Severe Air Quality
This pleasant weather stands in stark contrast to the conditions on Thursday, December 4. The city's air quality was classified as 'Severe', with an alarming Air Quality Index (AQI) reading of 326.
The primary culprits were dangerously high levels of particulate matter. PM2.5 concentration was recorded at 197 micrograms per cubic meter, while PM10 levels were at 252 micrograms per cubic meter. Both figures were far above the safe limits prescribed by health authorities, posing significant risks, especially for individuals with respiratory issues.
Advisories for Residents and the Week Ahead
While today's sunny and breezy weather will help disperse some pollutants, experts warn that effects from yesterday's severe pollution may still linger, particularly in high-traffic zones. Residents are advised to take certain precautions:
- Carry a mask if venturing into congested or traffic-heavy areas.
- Those with respiratory sensitivities should avoid prolonged outdoor exposure.
- It is wise to keep indoor air purifiers active.
- Wearing sunglasses is recommended for the sunny afternoon.
The good news is that the pleasant weather is set to continue. The forecast for the coming week in Kolkata predicts consistently sunny and clear days with no rain or extreme temperatures in sight.
The weekly outlook is as follows:
- December 6: Sunny, 14.9°C to 27.2°C
- December 7: Clear, 15.5°C to 26.4°C
- December 8: Sunny & warm, 15.8°C to 27.5°C
- December 9: Clear, temperatures up to 28.1°C
- December 10: Sunny & pleasant, 16.9°C to 28.5°C
While the week is ideal for outdoor schedules, continuous monitoring of air quality updates is recommended, as clear and dry conditions can sometimes trap pollutants. Today's data, sourced from AQI.in, marks a significant and welcome shift for Kolkatans looking forward to enjoying the winter sun.
