Mumbai woke up to hazy and unusually warm conditions on February 4, but dense smog soon engulfed the city, reducing visibility and highlighting persistent air pollution. The city’s AQI stood at 280, almost unchanged from the previous day. Areas like Sewri West and Wadala reported ‘Severe’ pollution levels, raising health concerns for residents.
The city woke up to a hazy and unusually warm morning on February 4, but the brief respite did not last long. As the day progressed, a dense layer of smog settled over Mumbai’s skyline, significantly reducing visibility for early-morning commuters and once again spotlighting the persistent air pollution problem that continues to plague the city.
Meteorological data from the Indian Meteorological Department (IMD) indicate that Mumbai will witness partly cloudy skies accompanied by hazy conditions through the day. Temperatures are expected to hover between 21°C and 34°C, a range that signals the gradual transition towards peak summer. Despite the change in weather patterns, air quality levels have largely remained unchanged.
This marks a reversal from recent trends, when select pockets of Mumbai had briefly reported better air quality. With most regions now slipping back into poor or worse categories, concerns are mounting over the effectiveness of pollution-control measures as the city heads into the hotter month
