As winter deepens across Bangladesh, a distinct drop in temperatures is being observed nationwide, with the Bangladesh Meteorological Department (BMD) forecasting cooler days and nights, expecting temperatures to decline further in the coming weeks.
In its latest 72-hour forecast issued on Tuesday night, the BMD said nighttime temperatures are likely to fall by 1–2°C, while daytime temperatures could also experience a slight decline.
The weather is expected to remain mostly dry, with light to moderate fog in some areas during the late night and early morning hours.
A seasonal low-pressure system over the South Bay of Bengal and its extension into the Northeastern Bay has contributed to these conditions, marking the transition into a more typical winter pattern.
The five-day extended outlook suggests temperatures may dip even further, intensifying the chill across the country.

Historical context, cultural significance
Winter in Bangladesh is a season of festivities and agricultural activities.
Farmers utilize this time to cultivate crops like rice and vegetables under favourable conditions.
Cities and rural areas alike embrace the cooler weather, with fairs, weddings and outdoor events in full swing.
However, the chillier nights and potential fog can pose challenges for vulnerable communities, particularly in the northern districts, where temperatures tend to be lower.
Travellers are advised to exercise caution during early morning hours when visibility may be reduced due to fog.

The BMD recommends light jackets for evenings and early mornings and staying updated on weather conditions, especially for those travelling long distances.
International visitors are encouraged to explore Bangladesh during this period, with key destinations like Cox’s Bazar, the Sundarbans and tea gardens in Sylhet offering an ideal blend of pleasant weather and scenic beauty.
