Ireland has a temperate oceanic climate heavily influenced by the country's close proximity to the Atlantic Ocean. The average temperature is 50 F. The climate is mild and moist with plenty of rainfall and no extreme variances in temperature.
The North Atlantic Current carries warm water to Ireland, which results in warmer winters and prevents ice formation on the coast. Between February and April, the temperature ranges from 46 F to 54 F. From May to July, the average temperature is between 64 F and 68 F. From August to October, the average drops to a range of 57 F to 64 F. January and February are considered the coldest months, with temperatures occasionally at or below freezing. Each year Ireland experiences over 40 days of air frost.
May and June are the sunniest months of the year, with an average of five to six hours of sunshine per day. The months of December and January receive the most rainfall, surpassing 118.1 inches. Fogs occur between eight and 99 days a year. Snow, hail, thunderstorms and tornadoes are rare. Each year less than 10 tornadoes are reported. Any unpredictable weather in Ireland is caused by the influence of the Gulf Stream, the North Atlantic Drift, the Atlantic Ocean, Ireland's latitude and Arctic winds.
