Cork, on Ireland’s south coast, receives around 1,150 mm (about 45 inches) of rain a year, considerably more than Dublin given its more direct exposure to Atlantic weather systems arriving from the southwest. The River Lee, which splits to flow through the city center on two channels, has a documented history of flooding during periods of heavy, sustained rain, prompting significant flood-defense investment in the city center in recent years. Rain here tends to fall as frequent, moderate showers rather than sudden violent downpours, consistent with Ireland’s broader Atlantic-influenced climate. Because prolonged rain combined with the river’s flow matters here, radar helps track exactly how intense an approaching band is. Met Éireann operates the national radar network.
