A severe heatwave swept across Delhi on Sunday with the maximum temperature touching 49.2 degrees Celsius in the city’s Mungeshpur area, PTI reported.

For the plains, a heatwave is declared when the maximum temperature goes up to 40 degrees Celsius or more and is at least 4.5 degrees above normal. A severe heatwave is declared if the maximum temperature crosses over the 47-degree Celsius mark.
The temperature at Safdarjung Observatory, the city’s base weather station, hit 45.6 degrees Celsius. This is five notches above the normal and the highest this year so far, PTI reported. This is also the fifth heatwave in Delhi this summer season.
The Safdarjung Observatory had recorded a temperature of 44.2 degrees Celsius on Saturday and 42.5 degrees Celsius on Friday.
“Heatwave conditions likely to continue over Northwest and Central India today and decrease in intensity and distribution from tomorrow [Monday],” the India Meteorological Department on Sunday.
The weather department has issued an orange alert, warning about severe heatwave conditions in the national capital.
“We have issued an orange alert for Punjab, Haryana, Uttar Pradesh, eastern Madhya Pradesh and Delhi,” Naresh Kumar, a senior scientist at the India Meteorological Department, told ANI.
In Haryana’s Gurugram, the mercury soared to 48.1 degree Celsius on Sunday evening.
The weather department said a thunderstorm or a dust storm is likely in Delhi on Monday.
“We can expect a significant decrease in the temperature after 24 hours which will eventually decrease the condition of a severe heatwave in northwest India,” Kumar said.
Delhi, as well as parts of Haryana and Uttar Pradesh, have been experiencing record high temperatures over the past two months. In the last week of April, the city saw temperatures rise up to 46 degrees Celsius due to a heatwave.
The average maximum temperature in April for northwest and Central India was the highest in 122 years. The country had also witnessed the hottest March in 122 years since the India Meteorological Department started maintaining records.
