The Gulf Stream provides a temperate maritime climate in Ireland. In summer, the average maximum temperature is between 15 and 20 degrees, and in July and August temperatures can rise to 25 degrees on some days. The winters are quite mild with average temperatures between 4 and 7 degrees, only rarely the temperatures sink below freezing. The situation in the Atlantic Ocean gives Ireland very changeable weather. Low pressure areas are always covered by rain clouds over the island. Thus often and also plentifully precipitation falls. Fast weather changes are not uncommon. In the west and in the interior the precipitation sums are generally larger than in the east.
The best time for a holiday in Ireland is from June to September, although the weather is very unstable even in summer.
