Dhaka: Bangladesh is likely to experience hot and humid weather conditions across the country during Eid-ul-Azha, while chances of rainfall remain high in the northern, northeastern, and some eastern regions, according to the Bangladesh Meteorological Department (BMD).
According to Bangladesh Sangbad Sangstha, Meteorologist A.K.M. Nazmul Haque of the Storm Warning Centre stated that rainfall is expected to be more significant in the Rangpur, Mymensingh, and Sylhet divisions, along with eastern districts of the Dhaka division, including Narsingdi, Narayanganj, Manikganj, and Kishoreganj. Moderate to heavy rainfall may occur in these areas before, during, and after Eid, accompanied by temporary gusty or squally winds, lightning, and light to moderate thundershowers.
Haque highlighted that while Bangladesh has only eight divisions, there are noticeable regional differences in weather patterns. The main focus remains on the Rangpur, Mymensingh, Sylhet, and the eastern part of the Dhaka division, where the likelihood of rainfall during Eid is considerably higher. In contrast, rainfall chances are comparatively lower in the Rajshahi, Khulna, Barishal, and the central part of the Dhaka division, including the capital.
Localized cloud cells frequently develop during April and May, often causing sudden short spells of rain lasting eight to ten minutes. Due to the changeable nature of weather systems, providing 100 percent accurate forecasts is challenging. Sometimes, rainfall begins three hours earlier than predicted, making pinpoint or time-specific forecasting a major challenge.
Rainfall is also likely in parts of the northern Chattogram region, including Cumilla, Noakhali, and Feni, during the Eid period. The current rainfall in different parts of the country is mostly occurring with thunderstorms, gusty winds, and lightning, which is typical for this time of year.
Mild to moderate heatwave conditions may affect parts of the Khulna division and some areas of the Rajshahi division, particularly Rajshahi, Pabna, and Ishwardi. Even in areas without heatwaves, humid conditions will persist nationwide and may continue until the beginning of June, before the full onset of the monsoon.
Regarding the monsoon, conditions are becoming favorable for its arrival. May 29 is considered the normal onset period of the monsoon in Bangladesh, and it may enter the country through Chattogram within the next week. Until then, hot and humid weather is expected to continue.
