Kolkata Experiences Warm Sunny Skies While Air Quality Remains Poor
Kolkata woke up to clear skies and warm temperatures on Friday, October 18, 2025, with daytime highs reaching 32.7°C and humidity at 65%. While the autumn sunshine creates favourable conditions for outdoor activities, city officials have highlighted concerns over poor air quality, with the Air Quality Index (AQI) recorded at 188 yesterday, primarily due to elevated PM2.5 and PM10 levels. Experts caution that vulnerable groups should take precautions during outdoor exposure.
The Met Office reports that light winds averaging 10.8 km/h will accompany today’s sunshine, contributing to comfortable travel and outdoor experiences despite the heat. However, the high levels of fine particulate matter in the atmosphere, combined with elevated carbon monoxide concentrations, underscore ongoing pollution challenges in Kolkata. Officials note that current moderate winds may help disperse some pollutants, but commuters are advised to exercise caution in high-traffic areas.
Environmental analysts emphasise that the recorded PM2.5 levels of 86 µg/m³ and PM10 levels of 150 µg/m³ pose health risks, particularly for children, the elderly, and individuals with respiratory or cardiovascular conditions. City authorities recommend scheduling outdoor activities during early morning or late evening hours when temperatures are cooler and pollution levels are relatively lower. Protective measures, including masks in congested areas, are advised.
Looking ahead, Kolkata’s weather forecast predicts patchy rain on Saturday, October 19, with an 83% chance of showers and slightly higher temperatures ranging from 24.2°C to 32.9°C. Clear skies are expected to return on Sunday and Monday, with daytime highs near 33.2°C and nighttime lows around 25.1°C. Experts suggest that the combination of dry conditions and moderate winds could help improve air quality temporarily, though residents are urged to remain vigilant.
Urban climate specialists point out that Kolkata’s current weather pattern reflects typical autumn conditions, with warm days and cooler nights offering opportunities for outdoor activities. They note that while sunny conditions are ideal for commuting and leisure, sustained urban pollution remains a challenge, highlighting the need for broader sustainable transport and environmental policies.
Officials confirm that continuous monitoring of AQI and pollutant levels remains a priority. Public awareness campaigns and advisory measures aim to ensure citizens can plan activities safely, balancing outdoor enjoyment with health precautions. The city’s approach aligns with long-term goals of fostering eco-friendly, equitable, and sustainable urban living.
