If you want to maximize your chances of sunny weather on your trip to Ireland, go during the sunniest months in May, June and early July when days average five to 6.5 hours of sun a day. By going early in May and June, you can find sunny days and avoid the peak season for tourism during July and August. Temperatures are warmest during July and August with average temperatures in the 60s F and highs in the mid 70s F but you might find more wet days in late July and August.
Southeastern and southern Ireland around County Wexford, County Waterford and County Kilkenny have the driest and sunniest weather, with up to seven hours of sun on average per day during May and June. Rosslare, in County Wexford, is considered the sunniest and driest place in Ireland. This coastal town in southeastern Ireland has been a resort town for more than 100 years. In western Ireland’s County Kerry on the Atlantic Ocean, expect the wettest Irish experience.
The seasons right before and after summer make for some good travel experiences in Ireland, though the weather is often more inclement. Head to Ireland in April and May to see the wildflowers, and garden flowers in full bloom. By September and October, the festival season is in full swing with lots of activities to enjoy. The Guinness Cork Jazz Festival in Cork happens every year in late October and seafood lovers won’t want to miss the Galway International Oyster and Seafood Festival in late September.
The dawn breaks clear and sunny and you head out for a day of sightseeing, dressed optimistically in sandals and a sun hat. The clouds start gathering by 11 a.m. and soaking rains fall through lunch. By afternoon, the sun reappears glistening through the rain-damp country. Bring an umbrella or a rain slicker on all your daily activities so you’re not caught in the rain like a tourist. Get an umbrella or rain coat that folds up small so you can easily tuck it in your day pack when the sun is shining.
