Significant rise in temperature is likely over and around the Delhi region, commencing today and staying good till 25th Apr 2026. The day maximum is expected to breach the 40° mark daily and gradually climb to 43°C, when close to the weekend. The mercury levels will be about 5°C above the pentad normal and therefore, amount to heat wave conditions. The temperature has exceeded 40°C on three days in this month, with the highest maximum of 41°C recorded on 17th Apr 2026.
There is no active western disturbance moving across the mountains to influence the weather conditions of the plains. A dry circulation is marked over West Rajasthan and border areas, throwing hot southwesterly winds over Central Rajasthan, Haryana and the Delhi region. The day temperature may reach about 41°C today. Base station Safdarjung recorded a maximum of 39.5°C yesterday. Ridge observatory was the only exception, breaching 41°C mark yesterday. Isolated places may cross 42°C today in Delhi/NCR.
After the clearance of western disturbance from the mountains, the surface and low level winds are likely to pick up today. The rising temperatures and speedy winds, together, may trigger ‘loo’ conditions in the afternoon hours. Lack of clouding, resulting fair amount of sunshine, will raise the insolation and push the temperature bar beyond 40°C. Heat wave, accompanied with loo conditions, are likely between 21st and 24th April. A fresh western disturbance arriving late on 23rd Apr 2026 will bring some rains over Punjab, Haryana, North Rajasthan on the weekend. Delhi will be on the outer peripherals of the main system. The spill over effect may lead to some drop in mercury levels. Even, pre-monsoon activity may affect Delhi and neighbourhood between 25th and 28th April 2026.
