A dust storm hit several parts of the national capital in the evening bringing the mercury down marginally after a hot, sunny day.
The maximum temperature was recorded at 39.5 degrees Celsius, two notches above the season's average while the minimum temperature settled at 24.8 degrees, also two notches above the normal, said a Met Department official.
The drop in temperature is because of a Western disturbance prevailing over the northern region for the last three days.
According to Met office, this April has been the hottest in the last five years, with temperatures soaring as high as 44 degrees Celsius in Palam and 42 degrees Celsius in Safdarjung on April 16.
The humidity level in air remained less and oscillated between 60 and 18 per cent.
The weatherman has predicted overcast conditions for tomorrow.
"The skies will be partly cloudy. Dust haze is very likely to occur during morning and evening. The maximum and minimum temperatures are expected to hover at 39 and 25 degrees," the official said.
Yesterday, the maximum and minimum temperatures were recorded at 38.6 degrees Celsius and 25.8 degrees Celsius respectively.
