DHAKA, Jan 13, 2026 (BSS) - Weather may remain dry with temporarily partly cloudy skies over the country today, while a mild cold wave is likely to sweep at places over the northern and western parts, indicating a renewed spread of cold conditions compared to yesterday, according to the Bangladesh Meteorological Department (BMD).

The BMD forecast said a mild cold wave may affect parts of the north and west, suggesting a wider spatial influence than the previous day when the cold wave had eased and remained confined to a few northern districts. 

Light to moderate fog may occur at a few places over the country during late night to morning, which could again reduce visibility in low-lying and riverine areas, though the fog intensity is expected to be less severe than during recent dense fog episodes.

Night temperature may fall by 1 to 2 degrees Celsius and day temperature may fall slightly over the country. 

This forecast marks a clear contrast with yesterday's outlook, when daytime temperatures were largely steady.
 
The expected fall in both night and day temperatures indicates strengthening winter conditions, particularly in inland areas away from the coast.

The highest maximum temperature recorded yesterday was 30.0 degrees Celsius at Feni, while the lowest minimum temperature today was 8.0 degrees Celsius at Tetulia in Panchagarh. The figures underline a sharp thermal contrast between the south-eastern region and the northernmost fringe of the country.

The minimum temperature of 8.0 degrees Celsius at Tetulia confirmed that the northern districts continue to act as the cold nucleus of Bangladesh's winter, driven by cold northerly airflow and clear night skies that favour rapid heat loss. 

On the other hand, Feni's highest temperature of 30.0 degrees Celsius highlights the relative warmth of the south-eastern region. Proximity to the Bay of Bengal, higher moisture content in the air and greater daytime solar heating continue to keep southern and coastal areas warmer, even when cold conditions intensify in the north.

In Dhaka, winds were blowing from the north to north-west at a speed of 5 to 10 kilometres per hour, reinforcing the influence of continental air over the central region. Relative humidity in the capital stood at 78 percent at 6 am, a level conducive to fog formation during the early morning hours but lower than during peak cold-wave conditions.

Sunset in Dhaka will be at 5:32 pm today, while sunrise tomorrow is expected at 6:44 am.
