Several parts of Tamil Nadu experienced temperatures above 40 degree Celsius on Sunday with Vellore recording the highest at 43.7 degree Celsius, followed by Karur with 42.5 degree Celsius.

According to the meteorological department, Sunday was the hottest day in the year and the temperatures were between 38 to 43 degree Celsius. They also said that the interior parts of the states will remain hot in the coming days, reports by TOI. The temperature has increased by 4 degree Celsius in five days.

MeT experts said that except Chennai, Kanyakumari and Pamban, temperature was above 40°C in most parts of the state. “The temperature in Vellore can come down only if there is a cloud of cold breeze from somewhere. The likelihood is remote in the coming days,” they told Times of India.

However, the weather in Chennai will remain normal for the next two days but the city may have to face a hotter summer in May.

IMD officials told News Today, “Usually such drastic changes are recorded only in the month of June, as April is just a transition month. Though this is not southwest monsoon, where winds blow from West to East, the temperature difference was caused by a wind called Westerlies.”
