Northern Bangladesh, particularly Tetulia, is experiencing a sharp drop in temperature as winter begins to set in. According to the Bangladesh Meteorological Department, the minimum temperature in Tetulia was recorded at 13°C on Wednesday morning, with humidity at 97%. The previous days also saw temperatures hovering around 12.8°C to 13.4°C, signaling the onset of winter. Meteorologists predict that the first cold wave of the season may arrive in early December if sea conditions remain stable. Meanwhile, a low-pressure area or cyclone may form over the Bay of Bengal in late November, potentially bringing rainfall and rough seas. Fishermen along coastal areas have been advised to remain cautious. Experts note that while November’s remaining days may not see a significant increase in cold intensity, the true winter chill is expected to begin in December.
