    Times of India | 2 October 2025
  • Kolkata faces heavy rainfall on October 2, 2025, with temperatures ranging between 26°C to 29°C, accompanied by a high humidity of 88% and winds up to 20.5 km/h. The city recorded moderate air quality yesterday with an AQI-IN of 52, while the week ahead forecasts continued rain and humid conditions through October 8.

    The day's weather forecast indicates a 94% chance of precipitation, making rain almost certain. The dense cloud cover and persistent showers are expected to dominate the weather pattern throughout the day.

    The combination of rain and high humidity creates challenging outdoor conditions. The moderate winds might provide some relief from the muggy atmosphere, though residents are advised to carry umbrellas and appropriate rain gear.

    Yesterday's air quality measurements showed PM2.5 levels at 25 µg/m³ and PM10 at 50 µg/m³, with carbon monoxide reaching 426 µg/m³. These moderate levels may cause slight breathing discomfort for sensitive individuals.

    The current air quality shows improvement compared to earlier in the week. The ongoing rainfall may contribute to further reduction in pollution levels in the coming days.

    The weekly forecast predicts continued wet weather starting October 3, maintaining similar temperature ranges.

    October 5 and 6 will likely experience heavier rainfall with stronger winds up to 25 km/h.

    Weekend temperatures are expected to drop to around 24°C during nighttime, with persistent showers continuing through October 7 and 8. October 6 might offer slightly better conditions with reduced rainfall.

    Commuters should prepare for wet conditions with waterproof gear. Those with respiratory sensitivities are advised to use masks, particularly in enclosed spaces and high-traffic areas.

    Data for this weather report has been sourced from AQI.in, providing comprehensive information about Kolkata's weather and air quality conditions.
