Overview
- The heatwave has continued into mid‑October with daytime highs around 37–38°C and IMD yellow alerts active for Mumbai, Thane and several Konkan districts, according to recent bulletins.
- The IMD's Thursday bulletin recorded Ratnagiri as Maharashtra’s hottest spot at 38.8°C and noted many districts were reporting temperatures well above normal.
- Researchers and meteorologists point to the Urban Heat Island effect—dense high‑rise development, loss of green cover and trapped nighttime heat—as a local driver that keeps nights warmer and raises human heat exposure in central and southern Mumbai.
- Air quality varies sharply across the city: citywide AQI readings were reported in the satisfactory to moderate range but some stations such as Deonar measured levels above 150, raising health concerns for sensitive groups.
- Forecasts call for light to moderate rain over the weekend in Konkan, Pune and Satara that could ease temperatures temporarily, but officials warn this is a short‑term shift rather than a guaranteed end to above‑normal October heat.
