The climate of Dublin
Dublin, the capital of Ireland, has an oceanic temperate climate (Köppen climate classification Cfb) with cool summers and mild winters - similar to much of northwestern Europe. The city lies at the mouth of the River Liffey, while the low altitude Wicklow Mountain range forms the southern boundary. The Atlantic Ocean, the Gulf Stream, and the North Atlantic Drift significantly influence Dublin's climate, while its location on the east coast makes it the driest place in Ireland.
Temperature extremes are rare, but the humidity is high throughout the year. Average high temperatures rarely cross 20°C (68°F) during peak summer in July, while average lows are above freezing at 2.2°C (36°F) in peak winter in January. Occasional exposure to Arctic winds during the usually mild winter causes severe cold and snow showers. Annual rainfall is distributed evenly throughout the year and amounts to 762mm (30"). Snowfall is occasional, but frost is more common during the winter.
