According to the India Meteorological Department (IMD), very light to light rain, with winds reaching 30–40 kmph, was reported at many places of the Capital on Friday. Palam Airport recorded gusts up to 37 kmph, Jafarpur up to 33 kmph, while Pragati Maidan and Salwan Public School station recorded gusts up to 31 kmph.

Senior IMD officials said the change was caused by an active western disturbance, a weather system that brings moisture-laden winds from the Mediterranean region to Northwest India, often leading to rain, cloud cover and strong winds in winter.
Interestingly, the system also led to a sharp rise in the minimum temperatures. The Capital recorded a rise of about five degrees Celsius in the minimum temperature compared to Thursday, mainly due to cloud cover, with the day’s low settling at 13 degrees Celsius. Weather stations such as CRPF Campus, Jafarpur, Lodhi Road and Hindon recorded jumps of over 8 degrees Celsius by 5.30 am, as per IMD officials.
In terms of air quality, Pusa recorded the cleanest air with AQI of 179 (Moderate), while Wazirpur remained the most polluted at 328 in the ‘Very Poor’ category. Stations including IGI Airport, Lodhi Road, Mandir Marg and NSIT Dwarka also reported Moderate air quality.
According to the IMD forecast, Delhi is likely to witness a generally cloudy sky on Saturday, with shallow to moderate fog during morning and strong surface winds reaching speeds of 10–20 kmph. As per Indian Institute of Tropical Meteorology, Pune, air quality is expected to remain in the ‘Moderate’ category on Saturday, turn ‘Poor’ on Sunday, and fluctuate between ‘Poor’ and ‘Very Poor’ in the following days.
