Matara sits in Sri Lanka’s southwestern wet zone, where the southwest monsoon from May through September brings the island’s heaviest rainfall, supplemented by a second wet spell during the October-to-December inter-monsoon period.
At the mouth of the Nilwala River on the south coast, the city has a history of serious river flooding during intense southwest monsoon rain. The catastrophic May 2017 floods and landslides, triggered by an intense burst of southwest monsoon rain, remain the reference event for how quickly this densely populated region can flood, and Sri Lanka’s Department of Meteorology relies heavily on radar to track incoming monsoon rain bands.
