Summer in Ireland: Weather and Top Destinations

The summer season in Ireland runs from June to August, and temperatures generally range from 15 to 20°C (59°F to 68°F).The overall weather is pleasantly warm, though occasional rainfall is also common.

If you plan to explore the coastal areas in the west, like the Cliffs of Moher, expect slightly cooler temperatures and a higher chance of rainfall. However, inland and the east coast areas, such as the vibrant city of Dublin and the historic site of Newgrange, tend to be comparatively drier and bask in more sunshine, making them perfect destinations for outdoor adventures and sightseeing.

Due to its northern location, the country experiences long daylight hours during the summer months. In June, the country sees up to 17 hours of sunshine.
