Bangladesh lies between latitudes 20° and 27°N, and longitudes 88° and 93°E.
Bangladesh is in the Ganges–Brahmaputra River Delta or Ganges Delta. This delta is formed by the confluence of the Ganges (local name Padma or Pôdda), Brahmaputra (Jamuna or Jomuna also known as “Yamuna”), and Meghna rivers and their respective tributaries. The Ganges unites with the Jamuna (main channel of the Brahmaputra) and later joins the Meghna to eventually empty into the Bay of Bengal. The alluvial soil deposited by these rivers has created some of the most fertile plains in the world. Bangladesh has 57 trans-boundary rivers in most cases as the lower riparian state to India.
The highest point in Bangladesh is in Mowdok range at 1,052 m (3,451 ft) in the Chittagong Hill Tracts to the southeast of the country. Cox’s Bazar, to south of the city of Chittagong, has a beach that stretches uninterrupted over 120 kilometres (75 mi).
Straddling the Tropic of Cancer, Bangladeshi climate is tropical with a mild winter from October to March, a hot, humid summer from March to June. A warm and humid monsoon season lasts from June to October and supplies most of the country’s rainfall. Natural calamities, such as floods, tropical cyclones, tornadoes, and tidal bores occur almost every year.
