Johor Bahru sits in southern Peninsular Malaysia near the equator, where rainfall is heavy and fairly consistent year-round, though the northeast monsoon from November through January still brings the wettest and most flood-prone weeks.
Malaysia’s southernmost major city sits across the strait from Singapore, where rapid urban development has increased flash-flood risk during intense storms. Because the region combines constant tropical rainfall with the added risk of intense monsoon downpours in December and January, radar remains a key tool for distinguishing routine afternoon showers from the sustained rain events that lead to river flooding.
