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. Spring and autumn are very changeable and rainfall is expected all year round. In winter average temperatures are around 0 degrees Celsius (32 degrees Fahrenheit) inland and there is a chance of snow. However real winter weather is rare along the coasts.
Some years Ireland is struck by a heatwave during summer. But usually temperatures 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.
