The climate of Ireland: when to go to Ireland

Ireland is an island located in the Atlantic Ocean, its location and lack of large mountains makes its climate typically oceanic, climatic characteristics of the Irish climate is its extreme variability, its mild temperatures, frequent rainfall and persistent fog.

The Irish climate, as we have said, is characterized by extreme variability due to the rapid succession of air masses coming from the Atlantic Ocean, and the frequent rains, on average, in the country, we have over 200 days of rain all years, there is no dry season but it rains every month of the year.

The wettest region of the island are the areas of south-western mountain slopes, where there are about 3,000 mm of rain per year, in contrast the eastern coastal area is the driest, here the annual rainfall varies between 600 and 700 mm, but most of Ireland receives on average between 800 and 1,400 millimeters of rainfall a year.

With regard to the temperatures they are pretty warm, in summer average temperatures vary between 15°C and 20ºC, while in the colder months there are average temperatures between 3°C and 10°C.


To visit Ireland the summer months are most suitable, because they have very long and bright days and pleasant temperatures. Even the months between April and June and that of September can be good for a trip to Ireland.
