When is the best time to visit Ireland?

The best time to visit Ireland is between March and May, and September to November, when it’s not as crowded as it is in summer, or as cold as it is in winter. That said, Ireland has a mild, temperate climate and although it’s rainy at times, you can visit all year round. The changes in weather are not normally extreme.

Summer (June, July and August) is the warmest time of year, when Ireland’s landscapes are at their most vibrant and the days are at their longest. However, it’s also crowded and prices are at a premium.

Some sites close from late October, and temperatures drop, but on average, they remain above freezing even in winter. This can be a wonderful time to see Ireland at its most calm.

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.
