Delhi's air quality reaches year's best with AQI at 52 after early September rainfall surpasses annual average

Continuous rain has been observed in Delhi and nearby areas in the National Capital Region (NCR) over the past few days. According to the India Meteorological Department (IMD), the total rainfall in Delhi was recorded as exceeding 1,000 mm by early September, surpassing the usual annual and seasonal averages.

Heavy rain hits the city

Palam recorded 54 mm of rain, and the Safdarjung area saw 30.9 mm of rain in just three hours, on Friday. With this, Delhi’s total rainfall for the year has gone beyond 1,000 mm, even though the city usually gets around 650 mm during the monsoon.

This September, Delhi has already received 125.8 mm of rain—55% more than usual. The rain, which started on Wednesday night, has caused concerns about waterlogging, road flooding, and possible traffic jams in some areas.

Orange alert Issued

The weather department first issued a yellow alert for Friday, but due to the heavy rainfall, it was upgraded to an orange alert. This alert warns people about possible disruptions in transportation, power cuts, and other issues caused by severe weather.

Air Quality improves significantly.

On Friday, Delhi’s Air Quality Index (AQI) dropped to 52—the best so far this year. For comparison, last year’s lowest AQI was 45, recorded on September 10, according to data from the Central Pollution Control Board (CPCB).

Cooler weather expected

According to the weather department, the rain also brought cooler temperatures, with Friday’s maximum temperature at 27.6°C, which is six degrees lower than normal.

Despite the rain causing some challenges, like waterlogging and traffic delays, the improved air quality and cooler weather have been a relief for Delhi’s residents.
