Rain season
Dhaka's monsoon (June–October) delivers around 80% of its 2,000mm annual rainfall, with July and August the most intense. The Brahmaputra–Ganga delta setting makes flooding endemic — the city floods regularly even in moderate years. Cyclones from the Bay of Bengal (April–May, October–November) can bring catastrophic rainfall in hours. Drainage infrastructure is chronically overwhelmed.
