Please select your location:

Ireland has a mild, temperate climate and although at times rainy, you can visit at any time of year. Best, perhaps, are the months of March to May and September to November, as the weather isn’t as cold as during the winter months. The months of June, July and August are the warmest of the year, when Ireland’s landscapes are at their most vibrant. However, in summer sites (and roads) are crowded and prices at a premium. From late October some sites close, and temperatures drop but on average, remain above freezing even in winter. This can be a wonderful time to see Ireland at its most calm.

Trip ideas and travel guides to exploring Ireland

Max at Glendalough, County Wicklow, Ireland

While many visitors aim to see Ireland during its summer months (late June to August), for me, the ideal time to visit is around May. This time of year brings comfortable temperatures, with Ireland’s trademark green countryside and wildflowers in bloom. It also means you have a bit more of the island to yourself, pre-empting the biggest crowds and getting there before the local schoolchildren break for summer. While nobody can predict the weather flawlessly, the locals commented during my most recent May visit that I’d picked the ideal time to drop by.
