The rain predicted for the weekend proved elusive, ruling out chances of a dip in mercury before summer sets in.
A high-pressure belt that developed along the Bengal coast kept rain clouds away from the city on Sunday, said an official of the India Meteorological Department, Calcutta.
The minimum temperature, which has been rising for the past week, increased from 17.5 degrees Celsius on Saturday to 18.4, normal for this time of the year.
The Met office predicted that the minimum would touch 19 degrees on Monday and 20 the day after.
Sunday’s maximum temperature — 29.6 degrees Celsius — came down marginally from Saturday’s 30.5 because of a thin cloud cover.
“A cyclonic circulation over eastern India has brought rainfall to the western districts of Bengal but the clouds could not reach Calcutta because of a high-pressure belt along the coast. The high-pressure belt is the stronger of the two systems. Had the city received some shower on Sunday, there could have been a renewed, though short-lived, spell of chill,” said a Met department official.
The high-pressure system has triggered a flow of moisture from the sea, resulting in formation of thin clouds.
“The system is strong and the cloud cover will stay at least till Tuesday. The clouds, however, are not strong enough to trigger showers,” said a weather department official.
