Bangladesh has a hot, humid climate with high temperatures year-round due to its location on the Tropic of Cancer. Most rainfall occurs during the monsoon season from June to October, bringing 80% of the annual rainfall. Rainfall amounts vary widely across Bangladesh, from 1250 mm in the western region to 5500 mm in the northeast. Common climatic hazards include cyclones, tornadoes, and drought, with the country's location and monsoon rains making it vulnerable to these events.
