The last time Delhi had a lower maximum temperature this month was on April 1, 2023, however, if only the second half of the month was considered, when Delhi mostly sees temperatures above 40°C on a regular basis.
This is Delhi’s lowest maximum in at least 13 years, IMD data available since 2011 showed.
The last time Delhi had a lower maximum during the second half of the month was 29°C on April 17, 2019, IMD said.
Met officials said that a fresh western disturbance is expected in the coming days, with sporadic showers to continue till May 7.
During this period, Delhi is likely to see drizzle to light rain in parts of Delhi, along with strong winds, with the maximum temperature to stay below 35°C.
“The maximum is expected to be below 30°C till Wednesday. While it is likely to hover around 26°C today, it will be around the 27°C mark on Tuesday, with similar weather expected to continue,” said an IMD official.
Delhi’s minimum is meanwhile forecast to hover between 18-20°C till May 7.
The light drizzle also helped improve Delhi’s air quality.
Delhi’s air quality index (AQI) on Monday at 10am was 106 (moderate), while it had been 132 (moderate) at 4pm on Sunday – when the Central Pollution Control Board (CPCB) releases its national bulletin.
Forecasts show that the AQI is likely to remain in the moderate range on Monday, before improving to satisfactory on Tuesday.
The CPCB classifies an AQI between 0-50 as good, between 51 and 100 as satisfactory, between 101 and 200 as moderate, between 201 and 300 as poor, between 301 and 400 as very poor and over 400 as severe.
“Delhi’s air quality is likely to remain in the moderate category on May 1. The air quality will improve to the satisfactory category on May 2, before returning to moderate once again on May 3. The outlook for the subsequent six days shows Delhi’s AQI will largely be moderate,” said the Early Warning System (EWS) for Delhi, a forecasting model under the ministry of earth sciences.
