Cooga Cottage in Doon, County Limerick, Ireland

Thanks to the moderating effect of the Atlantic Gulf Stream, Ireland's climate is relatively mild for its latitude, with a mean annual temperature of around 10°C. The temperature drops below freezing only intermittently during winter, and snow is scarce - perhaps one or two brief flurries a year.
The coldest months are January and February, when daily temperatures range from 4° to 8°C, with 7°C the average. In summer, temperatures during the day are a comfortable 15° to 20°C. During the warmest months, July and August, the average is 16°C.
A hot summer's day in Ireland is 22° to 24°C, although it can sometimes reach 30°C. There are about 18 hours of daylight daily during July and August and it's only truly dark after about 11pm.
One thing you can be sure of about Irish weather is how little you can be sure of. It may be shirtsleeves and sunglasses in February, but winter woollies in March and even during the summer.
Regardless of when you visit Ireland, even in middle of the summer, you will more than likely experience rain, so if you intend being outdoors, a waterproof coat is recommended.
