The Safdarjung observatory registered a maximum temperature of 38.6 degrees Celsius, five notches above normal, making it the hottest day of March since 2011, said a Met department official.
The Palam observatory recorded a maximum temperature of 40.2 degrees Celsius, also the highest in the last seven years, while the temperature at Lodhi Road station was 39.1 degrees Celsius, the official said.
According to the India Meteorological Department (IMD), this March has been the hottest in the last five years with the maximum temperature hovering above the 35 degree mark on most days.
It felt like May in March this year with the early onset of summer, IMD scientist Charan Singh told NDTV. He added the heatwave conditions prevailing across western, central and Northern India will subside over the next 48 hours.
"The heatwave will gradually abate from the western parts of the country from Rajasthan and Gujarat and will subside in Madhya Pradesh too," he said.
However, he warns that this is not the end of the heat as the summer months are yet to arrive. "People should take precautions, avoid stepping out during peak afternoon hours and stay hydrated," Mr Singh said.
