Mahesh Palawat, vice president at Skymet, said consistent rains are expected in Delhi-NCR for at least a week. “There is a cyclonic circulation over Uttar Pradesh and West Bengal, which may merge. The monsoon trough should also remain close to Delhi. We can expect widespread rains in the entire Indo-Gangetic Plain belt for the next seven days. In Delhi, it will mainly be consistent light rain with intense showers at some places. The weather will remain pleasant,” he said.

The maximum temperature stood at 29.9°C on Thursday – five degrees below normal. The minimum was 24.7°C, which was two degrees below normal. The maximum is forecast to be between 33-35°C on Friday, while the minimum will remain close to 24°C.

The consistent rain has also helped to maintain the air quality. The average air quality index (AQI) stood at 59 (satisfactory) at 4 pmon Thursday. It was 66 (satisfactory) at the same time a day earlier.

The Commission for Air Quality Management (CAQM) on Thursday said July ended with an average AQI of 78, which is the lowest since 2018. The average AQI for the month of July was 96 last year, 84 in 2023, 87 in 2022, 110 in 2021, 84 in 2020, 134 in 2019, and 104 in 2018.
