When to take your Great Irish Trip

Ireland has a pretty moderate climate all over the country and it’s quite rare to get a very hot summer or extremely cold winter. The coldest months are January and February with average daily air temperatures of between around 4C and 7C. July and August are the hottest months, with temperatures between 14C and 16C and May and June are normally the sunniest. In Ireland, people like to say that you often end up getting all four seasons in one day!

It rains a lot here and no matter what time of the year you go, chances are slim that you'll make it back without having an encounter with a shower! But the rains are responsible for the brilliant green colour of the landscape...

The Seasons


Spring is a great season for touring the country: you’ll get warmer temperatures, flower-filled scenery and longer days. The weather's pretty rainy in the spring, but often, the rain showers last only part of the day, opening up the sky to sun and yes, even rainbows.


Summer is the most popular time to visit Ireland: temperatures stay comfortably warm and breezy during the day and drop to that perfect light-sweater temperature at night. In July and August there can be surprisingly warm weather, with average temperatures of around 15ºC -18ºC, occasionally as high as 30ºC.


Autumn is probably the most underrated time to visit Ireland — days are mild, with not too much rain, and daylight lasts until nearly 9 p.m., which is great for marathon sightseeing. Autumn is even less predictable – you could find yourself soaking up the sun but equally you could really need a warm and waterproof jacket.


Average temperatures in Ireland in January and February (usually the coldest months) are about 5ºC, though they can drop quite a bit lower at night. Ireland is spared snow, for the most part, and the temperature doesn't dip to extreme lows, but the forecast is often cold, rainy, and windy.
