The weather in Ireland can be changeable, but there is one constant: rain. No matter what time of year you discover the beauty of the green and shiny island, you must rely on a few showers. The seasons differ according to the region: the western part of Ireland is generally more rainy than the east of the island. In the south, it is on average up to three degrees warmer than in the north.


The Irish celebrate the official start of spring on February 1st, with February being one of the coldest and darkest months on the island.

In the spring, Ireland lives at the top of its green island name.

The months of April and May are particularly suitable for a stay in Ireland. The first rays of sun shine on the colorful landscapes of the country and the dark days of winter seem to be forgotten. In March, there is the least rainy day and up to 15 ° C in May.
