The number of regions experiencing a cold wave across the country decreased on Tuesday, although the lowest temperature dropped further. In contrast, temperatures showed a slight increase in the capital, Dhaka. According to the Meteorological Department, while some areas recorded lower temperatures today, a fresh nationwide drop is expected to begin from Wednesday and may continue for three to four days before temperatures rise again.

Weather officials reported that the lowest temperature today was recorded at Tetulia in Panchagarh, where the mercury fell to 7.5 degrees Celsius. The same location recorded 8.4 degrees Celsius on Monday and 7.3 degrees Celsius on Sunday. Tetulia has now remained the coldest place in the country for six consecutive days.

Cold wave conditions were reported today in three districts—Panchagarh, Kurigram, and Nilphamari. This marks a decline from eight districts affected the previous day, while ten districts experienced cold wave conditions the day before that.

The Meteorological Department classifies a mild cold wave when temperatures range between 8.1 and 10 degrees Celsius. A temperature between 6.1 and 8 degrees Celsius is considered a moderate cold wave, while 4.1 to 6 degrees Celsius is categorized as severe. Temperatures falling below 4 degrees Celsius are termed extremely severe cold waves.

Despite the reduced number of affected areas today, meteorologist Md Hafizur Rahman warned that temperatures could drop again starting Wednesday and may continue declining for up to four days. He added that a gradual rise is expected afterward.

Meanwhile, Dhaka recorded a rise in temperature compared to Monday. The capital’s minimum temperature increased by one degree to 16 degrees Celsius, up from 15 degrees the previous day.

Along with the rise in minimum temperature, the maximum temperature in Dhaka also increased. On Monday, the city’s highest temperature stood at 27 degrees Celsius. Meteorologists note that when the gap between maximum and minimum temperatures narrows, the cold feels more intense. On December 29 last year, Dhaka experienced an unusually small temperature difference of just 1.7 degrees Celsius—the lowest recorded in the past 72 years, according to weather office data.
