Ireland Weather, climate and geography
Weather & climate
Best time to visit:
Ireland's relatively temperate climate is due to mild southwesterly winds and the effects of the Atlantic Gulf Stream. Summers are warm – only rarely getting unpleasantly hot – while temperatures during winter are much cooler, although it’s far from common for the temperature to drop below freezing and snowfall is rare. Spring and autumn are very mild, with rainfall expected all year round.
The other chief characteristic of the climate, however, is its unpredictability. You might be basking in balmy T-shirt weather one week, then wrapping up to stave off the chill the next – all the while with an umbrella to hand.
Lightweights during summer with warmer mediumweights for the winter. Rainwear is advisable throughout the year. If you find yourself lacking anything essential on arrival, of course, all key centres are well stocked with clothing outlets, with the larger cities particularly good in terms of picking up high quality outdoor equipment. And it’s worth remembering that certain clothing items which are more commonly seen as souvenirs – hand-knit Aran sweaters, for example – can be practical purchases for the trip itself.
