Smog Grips Mumbai After Clear-Sky Forecast as Air-Quality Readings Diverge

Local reports link the sudden pollution spike to dust and fine particulates from ongoing construction and large infrastructure works.

Overview

  • IMD projected pleasant winter conditions near 18–33°C, yet a thick haze formed by late morning and reduced visibility in several areas.
  • Citywide AQI showed sharp discrepancies, with AQI.in reporting 273 in the unhealthy range while Sameer and SAFAR showed around 133 in the moderate band.
  • Multiple hotspots registered severe pollution, including Chembur and Wadala Truck Terminal at 345, Deonar at 322, Colaba at 317, and Mazgaon at 314.
  • Neighborhood readings varied widely, with some suburban pockets lower, such as Bhandup West at 94, Borivali at 113, Mazgaon at 123, and Colaba at 118 on the Sameer app.
  • Reporters noted a rapid deterioration after a brief improvement last week, and the unhealthy air poses heightened risks for people with respiratory and heart conditions.
