Bangladesh Weather, climate and geography

Geography

Bangladesh lies at the heart of the Ganges–Brahmaputra–Meghna delta, one of the most fertile and dynamic river systems in the world. Situated on the northern edge of the Bay of Bengal, the country is characterised by lush plains, winding waterways and a landscape that changes with the seasons. During the monsoon, vast areas transform into an intricate network of rivers and floodplains, while the dry season reveals rich agricultural fields and rural villages linked by narrow embankments.

The majority of Bangladesh sits barely above sea level, making water central to both daily life and national identity. Boats are often as important as roads, especially in the south and southwest, where shifting channels and tidal rivers shape local travel and commerce. To the southeast, the Chittagong Hill Tracts break the pattern of flat terrain with forested hills, waterfalls and diverse indigenous communities.

Along the coast, expansive beaches and mangrove forests dominate. The Sundarbans — a vast tidal mangrove ecosystem shared with India — forms a natural barrier against cyclones and is home to a remarkable array of wildlife. Further east, Cox's Bazar and neighbouring Teknaf offer long stretches of sandy coastline.
