Cairns sits in tropical northern Australia, where a monsoonal climate produces a hot, wet season from roughly November through April and a dry season for the rest of the year, with cyclones posing the region’s biggest flood risk.
In Queensland’s far north, the city sits in one of Australia’s wettest regions, with cyclones and monsoon troughs both contributing to its high annual rainfall. Cyclones crossing this coast can dump extraordinary rainfall totals in a short time, and because they can intensify rapidly right up until landfall, the Bureau of Meteorology’s radar network is essential for tracking a storm’s exact position and rain bands in real time.
