On the morning of February 1, 2026, residents of Delhi and the National Capital Region (NCR) woke up to wet weather as light rain lashed parts of the city, accompanied by thunderstorms. The India Meteorological Department (IMD) issued a yellow alert for the national capital, warning of thunderstorms, lightning, strong winds up to 40 km/h, and dense fog.
The rainfall has been triggered by a western disturbance affecting northwest India. Delhi has seen several such systems this month. At the Safdarjung weather station, January rainfall stands at 25.4 mm, which is 38% higher than the long-period average of 18.4 mm.
As of 6 a.m., the AQI in Delhi was 324, falling in the very poor category. The city recorded a minimum temperature of 6.7 degrees Celsius on Saturday, one degree below the seasonal average.
However, IMD expects night temperatures to rise on Sunday due to cloud cover trapping heat. “The minimum temperature is expected to be around 10-12°C on Sunday and 11-13°C on Monday. It is likely to fall again to around 7-9°C by Thursday,” an IMD official said.
For February 1, the forecast includes thunderstorms with light rain, shallow to moderate fog in the morning, and gusty winds. Maximum temperature around 18 degrees Celsius, minimum near 11 degrees Celsius, with high humidity. From February 2-3, moderate fog is likely in mornings, with maximums at 18 degrees Celsius and minimums between 11-12 degrees Celsius, and no warnings issued. Between February 4-6, persistent morning fog, day temperatures steady at 18-19 degrees Celsius, and nights dropping to 8-9 degrees Celsius by February 6.
