Heavy rainfall is characteristic of Bangladesh. With the exception of the relatively dry western region of Rajshahi, where the annual rainfall is about 1600 mm, most parts of the country receive at least 2000 mm of rainfall per year. Because of its location just south of the foothills of the Himalayas, where monsoon winds turn west and northwest, the regions in northeastern Bangladesh receives the greatest average precipitation, sometimes over 4000 mm per year. About 80 percent of Bangladesh’s rain falls during the monsoon season.
Lightweight cotton clothing is advised throughout the year, with an umbrella or raincoat for the monsoon season. You should be prepared for high temperatures and humidity, no matter where you go during summer. A sweater and warmer clothing is advised for cooler evenings. Warmer clothing is advised for the northern mountainous areas of Bangladesh, which can have quite cold winters.
