The city sweated and fretted on Tuesday as a late February day felt like April.
The minimum temperature shot up to 23.4 degrees Celsius, a staggering five notches more than what is standard for this time of the year.
The maximum temperature was 31.1 degrees, a notch above normal.
What made things more uncomfortable was the humidity quotient, which was on the higher side.
The minimum relative humidity was 51 per cent and the maximum was 91 per cent.
The sky was partially cloudy in the morning. But as the sun came out, the heat was unmissable.
On February 15, the minimum temperature was 15.3 degrees Celsius, meaning a rise of 8.5 degrees in a week. The flip-flop has triggered a spurt in viral infections, especially among children and the elderly.
People who stepped out during the day felt the heat. Ratul Ghosh, who works with a private bank, walked from the Jeevandeep gate of Maidan Metro station to Shakespeare Sarani, a distance of less than a kilometre.
“My shirt was wet by the time I reached Shakespeare Sarani,” said Ghosh.
A Met official said that the humidity quotient made the weather uncomfortable.
“The Celsius is likely to stay on the higher side over the next few days,” he said.
