The dominant influence on Ireland’s climate is the Atlantic Ocean. Consequently, Ireland does not suffer from the extremes of temperature experienced by many other countries at similar latitude.
Winters are mild with temperatures in the coldest months, January and February, rarely falling below freezing. The sunniest months are May and June with up to 18 hours of daylight. In the warmest months, July and August, temperatures can sometimes reach up to 25 C (78 F).
Visitors expect to see some rain and occasional mist during their visit, but are also likely to experience glorious sunshine, sweeping cloud formations, and beguiling rainbows. The weather can vary dramatically from day to day; it can also change from fair to showery and back again to fair in a matter of minutes. June is typically the driest month and the winter months of December and January are the wettest.
