Ireland’s climate is influenced by the warm waters of the Gulf Stream. The country is also, luckily, in the path of the prevailing south-westerly winds coming from the Atlantic Ocean. This makes for similar weather conditions over the whole country and means Ireland is never really exposed to extremes of weather. So, there are few snow storms but neither is there a lot of consistently warm weather.
It is said that we can (at times!) experience all four seasons in one day, so keep this in mind & pack wisely. Include warm indoor & outdoor clothing. Plan for the sun, the wind, & the rain, and be able then to get out & enjoy it all, whatever the weather does!
The coldest months are January and February, while July and August are warmest. Over the year it generally gets no colder than 1 degree Celsius (34 F) or warmer than about 20 degrees Celsius (68 F). Ireland is known as a wet place; Irish rain actually lends the country its uniquely green look. There’s rain all year round – but most often in the winter and in the western half of the country. Temperatures mid-year, in May, average at 14ºC.
Dublin enjoys reasonable sunshine and rain belts reaching the east coast. The rains are frequently light and generally clear within a few hours. May and June are the sunniest months, with between five and seven hours of sunlight each day.
