Delhi weather on September 12

The weather is expected to remain generally cloudy across Delhi on September 12. The forecast indicates one or two spells of very light to light rain accompanied by thunderstorms and lightning at many places.

The most significant rain activity is expected from the early morning to forenoon, with moderate rain possible at isolated places. Another spell of very light to light rain is forecast from the afternoon to evening.

The same broad weather pattern is forecast for North, North-East, North-West, West, South, South-West, South-East, New Delhi, Central, East and Shahdara districts.

Weather could be a factor during BRICS Summit

The timing of the forecast is notable as the 18th BRICS Summit is scheduled in New Delhi on September 12-13, 2026, under India's BRICS Chairship.

The summit is being held at Bharat Mandapam, with leaders from BRICS member countries expected to participate. The weather conditions on September 12 could therefore be relevant for movement of delegates, traffic management and outdoor activities around the national capital.

What Delhi residents and visitors should expect

With rain and thunderstorms possible across large parts of the capital and NCR, commuters should be prepared for wet roads and possible traffic disruptions, particularly during the morning period when the forecast indicates the highest likelihood of widespread thunderstorm and rain activity.
