Delhi-NCR weather: Late-night rain and thunderstorms bring temperatures down; check IMD forecast for October 25

Delhi-NCR witnessed a sudden change in weather late Saturday night as rain, thunderstorms and gusty winds swept across the region, bringing cooler conditions and hail in parts of Delhi and Noida. Showers were also reported in Ghaziabad, Gurugram and Faridabad.

The spell brought relief from relatively warmer conditions across the national capital and neighbouring areas. Delhi's air quality also showed an improvement, with the Air Quality Index (AQI) standing at 191 on Saturday, compared with 230 a day earlier. However, the improvement in AQI does not establish how much of the change, if any, was caused by the rain.

Delhi weather today: Will it rain again on October 25?

Delhi is likely to remain dry on Sunday, October 25, according to the India Meteorological Department (IMD) forecast. Haryana, Chandigarh and Noida are also expected to experience dry weather.


The forecast comes after late-night showers and thunderstorms brought a marked change in conditions across Delhi-NCR. The spell was accompanied by strong winds, with hail reported in parts of Delhi and Noida.

The wider weather situation across northern and central India remains unsettled, with the IMD forecasting rainfall, thunderstorms and gusty winds in several parts of the country.

Delhi AQI improves from 230 to 191

Delhi's AQI stood at 191 on Saturday, improving from 230 a day earlier. The readings indicate a decline in the level of air pollution, although the city continues to face air-quality concerns.

Rain and gusty winds can influence pollution levels by helping remove some pollutants from the air or dispersing them. However, the extent and duration of any improvement depend on several factors, including wind conditions and the sources of pollution.

The latest readings offer a snapshot of the change in Delhi's air quality rather than a guarantee that pollution levels will continue to fall.
