The capital saw a slight decrease in minimum temperature on Saturday (May 16, 2026), with forecast of strong gusts over the city for the next few days.

Safdarjung, the city's base weather station, recorded a minimum of 24.8° Celsius, 1.7° below normal. The minimum temperature was 26.2° Celsius a day before.

Other stations also recorded below-normal minimum temperatures. Palam recorded a minimum of 24.6° Celsius, 2.5° below normal, while the Ridge recorded 24.6° Celisus, 2.1° below normal.

"The drop in minimum happens when skies are clear, leading to more loss of heat from the earth's surface. Mostly clear skies are expected to persist through Saturday," an IMD official said.

According to India Meteorological Department (IMD) forecast, there is a "possibility of thundery development towards afternoon/evening" on Sunday, along with strong winds at 20-30 kmph, and occasional gusts at 40 kmph.

"Strong surface winds are expected to continue on Monday and Tuesday as well," the official added.

IMD has forecast the maximum temperature to be around 40-42° Celsius on Saturday (May 16, 2026).

As per CPCB standards, an AQI of 0-50 is considered 'good', 51-100 'satisfactory', 101-200 'moderate', 201-300 'poor', 301-400 'very poor', and 401-500 'severe'.
