According to AFP, Shah Alam, the deputy head of the weather office, said the lowest temperature was recorded at 3 degrees Celsius in the northern town of Syedpur.
He said the last time the temperature dropped below that level was in February 1968 when Bangladesh was still part of Pakistan.
"The temperature is the lowest in Bangladesh's history," he said.
