According to data from the Centre’s SAMEER application, Mumbai recorded an Air Quality Index of 76 at 10 am, placing the city in the satisfactory category. An AQI reading of around 81 for pollutants such as carbon monoxide, nitrogen dioxide, and particulate matter 10 also falls within the same range, indicating generally acceptable air quality, although individuals with respiratory sensitivities may experience mild discomfort.
Despite the overall satisfactory classification, certain pockets of the city recorded elevated pollution levels. Sion reported the highest AQI at 152, followed by Deonar at 112, both categorised as moderate, indicating comparatively higher pollution concentrations in these regions. Other localities, however, reflected better air conditions, including the Bandra Kurla Complex at 83, Byculla at 72, Chakala at 78, Colaba at 66, Bandra East at 72, Kurla at 96, Mazgaon at 59, and Worli at 54, all within the satisfactory range.
Cleaner air was observed in select areas, with Mulund West recording an AQI of 17 and Sewri registering 48, both categorised as good, indicating significantly lower pollution levels compared to most parts of the city.
Temperature readings further indicated stable weather conditions across Mumbai. Colaba recorded a minimum temperature of 26.0 degrees Celsius, while Santacruz registered 25.6 degrees Celsius. No rainfall was reported at either station.
Overall, while Mumbai continues to experience stable weather conditions with largely satisfactory air quality, the pronounced variation across neighbourhoods highlights persistent pollution hotspots that continue to affect localized air conditions.
Meanwhile, the national capital Delhi remains under a yellow alert for rain and thunderstorms at isolated locations, even as it experiences its first warm night of the year. Weather data indicates that minimum temperatures across several stations have risen sharply, ranging between 4.6 and 5.4 degrees Celsius above normal levels, fulfilling the criteria for warm night conditions.
According to the India Meteorological Department, warm night conditions are declared when the maximum temperature reaches 40 degrees Celsius or higher, and the minimum temperature remains 4.5 to 6.4 degrees Celsius above normal levels. Delhi’s maximum temperature on the day is expected to hover between 39 and 40 degrees Celsius, with forecasts indicating the possibility of thunderstorms and rainfall due to an active cyclonic circulation over the region.
The Air Quality Index in Delhi stood at 196, placing it in the moderate category, indicating noticeable but not severe air pollution levels.
The contrasting conditions in Mumbai and Delhi underscore the complexity of India’s urban weather patterns, where stable coastal climates coexist with heat-driven atmospheric changes and pollution fluctuations in inland regions, highlighting the growing importance of continuous environmental monitoring and public health preparedness.
