Sibu sits on the island of Borneo, where an equatorial climate brings heavy rainfall throughout the year with no pronounced dry season, though the northeast monsoon from November through February typically brings the heaviest totals.
On the Rajang River, Sarawak’s main inland port city depends on the river for transport and closely tracks its level during heavy rain. Many of Borneo’s towns sit along rivers that are the primary transport routes in the region, so a sustained heavy rain event upstream can raise water levels significantly downstream, making radar an important complement to river-level monitoring here.
