Climate and Average Weather in Ireland

Ireland enjoys a temperate oceanic climate, due mainly to its proximity to the Atlantic Ocean and the presence of the Gulf Stream. Summers are mild and temperatures during winter can be cool. All seasons are very changeable and rainfall is expected all year round. In winter average maximum temperatures are around 0 degrees Celsius (32 degrees Fahrenheit) inland and there is a chance of snow. Real winter weather is rare along the coasts.

Usually temperatures in summer are not very high, the average maximum daytime temperature in Dublin lies around 19.6°C (67.28°F) in July. This makes it the hottest month of the year. Some years Ireland is struck by a heatwave.

It is often said that it rains a lot in Ireland, but if you a look at the climate statistics it shows that this is only partly based on truth. The west is indeed very wet and has a fairly large number of rainy days. However the east is a lot drier.
