Kolkata residents can expect a sunny day on October 16, 2025, with temperatures ranging between 21.5°C and 31.1°C, while dealing with poor air quality from the previous day that recorded an AQI-IN of 134 due to elevated levels of PM2.5 and PM10 pollutants.
The day begins with clear skies and comfortable temperatures in the morning. By midday, the mercury will reach 31.1°C with moderate humidity at 62%, accompanied by a gentle breeze of 12.2 km/h throughout the day.
The current weather conditions offer ideal opportunities for outdoor activities, particularly in the morning hours. The sun will set at 5:11 PM, bringing a gradual decrease in temperature to a mild 21.5°C in the evening.
Yesterday's air quality measurements showed concerning levels of pollutants in Kolkata. The AQI-IN value of 134 placed the city in the 'poor' category, with PM2.5 at 64 µg/m³, PM10 at 127 µg/m³, and CO levels at 310 µg/m³.
Air quality data shows a minor variation in pollution levels, with yesterday's AQI of 134 showing a slight increase from the previous day's reading of 130. Both measurements remain within the 'poor' category.
Residents planning outdoor activities should consider wearing masks in high-traffic areas despite the sunny weather, which may help disperse some pollutants. The morning hours are particularly suitable for outdoor exercises and activities.
The clear weather forecast for the coming week suggests potential improvements in air quality, though current pollution levels require continued attention from residents, especially those with respiratory sensitivities.

The following days, October 20 and 21, will see slightly higher temperatures reaching 33°C and 33.3°C respectively. Night temperatures will remain mild, creating comfortable conditions for evening activities.
October 22 will maintain the warm trend with a high of 33.2°C and continued sunny conditions. This weather pattern provides favorable conditions for weekend outdoor activities.
