Bangladesh climate overview

Bangladesh is largely surrounded by India, with a coastline onto the Bay of Bengal. This predominantly Muslim country was originally part of the Indian province of Bengal, gaining its independence from Britain in 1947, and from Pakistan in 1971. It is densely populated and frequently ravaged by natural disasters.

The vast majority of the country is a lowland delta where the mighty Ganges and Brahmaputra rivers empty into the Bay of Bengal. The landscape becomes very heavily intersected by minor rivers in the south, giving rise to extensive lush marshland such as in the Sundarbans National Park.

Further north, where the fertile land is not quite as sodden, bamboo, mangoes and palms grow. In the far north there are also extensive tea and jute plantations, particularly close to the hilly northern border with India, which is known for its scenic waterfalls.

In stark contrast to the rest of the country are the hills, ravines, and cliffs in the far southeast, known as the Chittagong Hill Tracts. A rolling landscape is clad in dense jungle with idyllic lakes, and is home to a few Buddhist tribal settlements.

Light rains sweep across the country from about mid-March to mid-May, during which time the temperature gets progressively hotter. Then from mid-May the Southwest Monsoon sets in and forces widespread rain and extensive cloud across all areas ensuring that temperatures do not rise any further from the highs in May, although they still remain hot with high humidity. The rain retreats by mid-October leaving a warm, sunny, and much drier winter.

The country is prone to cyclones from May to June and October to November, as well as flooding and occasional tornadoes.
