The weather office forecast that the mercury may fall further for a few days and the cold spell might last until the first week of February.
The forecast comes when fog has been disrupting ferry services and causing long tailbacks on the highways.
The weathermen, however, said this spell could be the last of this winter.
"The temperature may fall in a day or two and last till the first week of February," said Bazlur Rashid, meteorologist of Dhaka Met office.
Dhaka city's lowest temperature this winter was recorded at 11.8 degrees Celsius yesterday, while the country's lowest temperature was recorded at 9.7 degrees Celsius in Sreemangal, he said.
