A mild cold wave is sweeping through Naogaon, Panchagarh, Jashore and Chuadanga, said the Bangladesh Meteorological Department (BMD) today.
The lowest temperature in the country was recorded at 8.7 degrees Celsius in Tetulia in the 24 hours to 6:00 am today. The highest temperature was recorded at 29.0 degrees Celsius in Cox's Bazar.
When the temperature drops below 10 degrees Celsius or less and continues for some period, it is considered a cold wave, according to the BMD.
Different parts of Bangladesh experience different intensities of cold waves. Temperature between eight to 10 degrees Celsius is considered a mild cold wave, six to eight degrees Celsius a moderate cold wave and less than six degrees Celsius a severe cold wave.
Moderate to thick fog may occur at places over the country from midnight till morning, added the BMD.
"Weather may remain dry with temporary partly cloudy skies over the country. Night and day temperatures may remain nearly unchanged," it also said.
