Ireland Weather & Climate

Ireland’s climate, while often changeable and sometimes unpredictable, is never extreme. However the weather is a common topic of conversation in Ireland due to the varied conditions that can be experienced either in one day or throughout the course of a week and so the locals like to discuss it, a lot. Ireland’s climate is primarily influenced by the Atlantic Ocean meaning it doesn’t experience the extreme temperatures that many other countries with similar latitude do.

The North Atlantic Drift, a warm major ocean current, keeps temperatures in Ireland relatively mild and the coastal mountains and hills shelter the rest of the country from strong winds that tend to come off the ocean. So while the weather may change often, conditions are rarely extreme. Which means there’s really no ‘bad’ time to visit Ireland, just different times.

Spring is from February to April and temperatures range from 8°C to 12°C with the weather in April known as some of the most pleasant. Summer from May to July obviously attracts the highest temperatures with averages between 18°C and 20°C. July and August are the warmest months and also see the longest days with approximately 18 hours of daylight and darkness not falling until 11pm or later.

The temperatures in autumn, from August to October and still pleasantly warm staying around 14°C to 18°C and September is a rather mild and temperate month. Winter is obviously the coldest season with inland temperatures falling to 8°C. January and February are the coldest months and although the temperature can drop below freezing during this time, there is rarely much snowfall, aside from the occasional freak cold snap.

As you’d expect, summer is generally the most popular season for visitors thanks to the longer days, warmer temperatures and many festivals that are held during this time. Autumn and springs are less busy seasons when it comes to travellers however it is still a stunning time to visit as the leaves turn bronze and fall to the ground. The cooler conditions of winter can sometimes keep tourists away however it is a unique time to see the landscape while spring starts to see the return of visitors as the weather starts to warm up again and the landscape comes back to life.
