Cilegon sits on Java, where a monsoonal climate brings a wet season from roughly October through March and a drier season from June through September, with the wettest months typically producing the most intense flooding.
On the Sunda Strait in Banten, the city’s industrial waterfront faces combined rainfall and coastal flood risk. Jakarta’s catastrophic New Year 2020 floods, among the worst in the capital region’s history, showed how intense monsoon downpours combined with the area’s dense urban development and low-lying terrain can overwhelm drainage very quickly, and Indonesia’s BMKG meteorological agency relies heavily on radar during the peak wet-season months.
