Cox's Bazar is located 150 km (93 mi) south of the divisional headquarter city of Chittagong.Cox's Bazar town has an area of 6.85 km2 (2.64 sq mi), and is bounded by Bakkhali River on the north and East, Bay of Bengal in the West, and Jhilwanj Union in the south.[12]
The beach in Cox's Bazar has a gentle slope and with an unbroken length of 155 km (96 mi) it is often termed the "longest natural unbroken sea beach" in the world.
Cox's Bazar lies on a coastal plain in the southeastern corner of Bangladesh. From above, the plain appears to bulge out into the Bay of Bengal. Along the shore is an extensive area of beach and dunes. Most of the city is built on a floodplain that is lower in elevation than the dunes, making it more susceptible to flooding due to cyclones and storm surges. The Cox's Bazar coastal plain was formed after the sea reached its present level around 6,500 years ago, with the area of the current floodplain originally forming a sediment sink that has since been gradually filled in by the Bakkhali river as well as smaller streams coming down from the hills.[13]
The climate of Bangladesh is mostly determined by its location in the tropical monsoon region: high temperature, heavy rainfall, and generally excessive humidity, with distinct seasonal variations.[14] The climate of Cox's Bazar is mostly similar to the rest of the country. It is further characterised by the location in the coastal area. The annual average temperature in Cox's Bazar is a maximum of 34.8 °C (94.6 °F) and a minimum of 16.1 °C (61.0 °F). The average amount of rainfall is 3,524 mm (138.7 in).
