Mumbai woke up to cold and hazy conditions on Tuesday, February 3, 2026, with smog blanketing several parts of the city, once again highlighting concerns over deteriorating air quality that have persisted since the onset of winter.

According to the India Meteorological Department (IMD), the city is expected to witness mostly clear weather through the day, with temperatures ranging between 23 degrees Celsius and 32 degrees Celsius. While temperatures have remained largely stable in recent days, air pollution levels have continued to fluctuate, raising health concerns among residents.

Data from the Sameer app indicated that Mumbai’s overall Air Quality Index (AQI) stood at 137 on Monday morning, placing it in the ‘moderate’ category. Pollution levels varied significantly across locations, with Bandra Kurla Complex recording an AQI of 136, Borivali East 130, Byculla 157, Andheri East 185, Chembur 118, Colaba 128, and Deonar 147. Ghatkopar registered an AQI of 158, Kandivali East 125, Malad West 122, Mazgaon 133, while Mulund West reported the highest reading among key areas at 131.

On Tuesday, Mumbai’s AQI was recorded at 141, continuing to remain in the ‘moderate’ category and indicating little change from the previous day’s readings.

Officials noted that PM10 remains the dominant pollutant, primarily driven by construction-related dust and vehicular emissions, contributing significantly to the city’s air quality concerns.
