Best time to visit Ireland

When considering the best time to visit Ireland, it’s important to expect the unexpected —rain and wind are always a possibility, especially along the west coast, where Atlantic weather systems dominate.

If your trip planning to Ireland includes lots of outdoor adventures, know that rainfall varies across the country. The east and southeast coasts see about 150 rainy days per year, while the west and southwest can experience up to 225 wet days annually.

April is the driest month, while December and January are the wettest. That said, Irish weather is notoriously changeable, and a gloomy morning can turn into a sunny afternoon. The sunniest months tend to be April, May, and June, with July and August bringing the warmest temperatures. For the best chance of sunshine, the southeast is your best bet.
