Winter Chill Eases in South Bengal
This winter in south Bengal has been one of the coldest in a decade.
From mid-December to mid-January, the days were much colder than usual, with the average daytime temperature being more than two degrees below normal.
The nights were also quite cold, with the average nighttime temperature being the second lowest in a decade.
The cold was caused by a mix of factors, including fog, clouds, and strong winds from the northwest.
The weather office predicts a slight rise in temperatures next week, but it won't be very warm.
The average daily maximum temperature during the peak winter period was 23.1° Celsius, the lowest in at least a decade.
Only one day recorded a maximum temperature above normal, with the remaining 30 days below average.
The mean daily minimum temperature was 14.1° Celsius, making it the second lowest in a decade.
The prolonged chill was due to dense fog, persistent clouds, and uninterrupted northwesterly winds.
The Met office forecasts a rise in temperatures next week, but it is not expected to be sharp.
