To get you clued up about the best time of the year to visit Ireland, here’s our guide to the seasons, the weather, and why you can still enjoy a trip at any time of year.

When is the Best Time of Year to Visit Ireland?

The best time to visit Ireland depends on your preferences and what you want to experience during your trip. Depending on your weather preferences and the kinds of things you want to do whilst you’re there, different seasons will suit different travelers. 

Ireland has a temperate maritime climate, so it doesn’t experience extreme temperature fluctuations. It does have distinct seasons though, each showcasing a different side to the country and different weather conditions to take into account.

Here’s what to expect from each season and whether it includes the best months to visit Ireland.

Ireland in Spring (March to May)

Spring is a lovely time to visit Ireland. The weather is starting to warm up, and the landscapes are turning lush and green. Spring flowers are in bloom, and it’s a great time for outdoor activities like hiking or cycling. 

Average high temperatures in April in Ireland can reach a lovely 59°F (15°C), but they can also drop down to 37°F (3°C) at the start of March, so don’t be fooled by the sunshine. You should also be prepared for some rain, as showers can be frequent throughout the spring and damp weather may last for days.

Ireland in Summer (June to August)

Days are long, and you can enjoy festivals, outdoor events, and explore the stunning coastlines. However, it can get crowded, and accommodations may be more expensive, as the highest number of tourists visit Ireland at this time of year.

The Best Time for an Irish Experience

The lush green promise of spring, those endless summer evenings, the kaleidoscope of fall leaves, and the still beauty of a frosty winter’s morning. We love them all, which is why we feel that the best time of the year to visit Ireland is all year round!

If you are hardy enough, like we are, you can probably get away with a pair of shorts every day when you are here on holiday (less to pack and wash, so more environmentally friendly as well!).

But as we say, we are not made of sugar, so you won’t melt with a bit of rain on ya. It’s definitely not uncommon to see a man in shorts and wearing a woolly hat on his head walking down the street in the wintertime here. 😆

Ultimately, the best time to visit Ireland depends on your interests and tolerance for crowds and unpredictable weather. Consider what activities and experiences you prioritize, plan your trip accordingly and be prepared.
