From charming cities steeped in history to a rugged coastline kissed by the wild Atlantic Ocean, Ireland has a treasure trove of experiences to captivate the soul. 

Unlike other destinations, Ireland is not known as a land of extremes. Temperatures are fairly mild year-round while severe weather events are rare and the climate doesn’t vary much between geographic regions.

That said, there are still a few things you definitely want to consider before you pack your bags for the Emerald Isle.

In this guide, we’ll go over each season in detail so you can decide on the best time to visit Ireland for your travel style and preferences.

Psst! Don’t miss these tips and mistakes to avoid while planning your trip to Ireland! (You’ll thank us later!)

When is the best time to visit Ireland?

The best time to visit Ireland overall is during shoulder season, either mid-April to May or September to October. These months offer plenty of daylight hours and mild temperatures, but without the crowds and price hikes of peak tourist season (summer).

However, the dark, rainy winters can be cozy as heck and the summer months guarantee that even seasonal attractions and Airbnbs will be open. So, the best time to visit for YOU largely depends on what you want to see and do. 

Answer these questions to get started:

  • What region of the country do you plan to visit?
  • Are you easily bothered by crowds?
  • Are you negatively affected by rain and cold?
  • Do you prefer to spend your time in nature or exploring a new city?
  • Are you planning to do activities like hiking and spending time outdoors?

Thinking about your answers to these questions is going to help you start to determine when to visit Ireland.

Trying to decide whether to visit Ireland or Scotland? You’re not alone! We’ve done both, and we have a whole guide where we compare the two and give our personal recommendation on the Scotland vs. Ireland debate.

Our experience

We visited Ireland in June

Wicklow Ireland
Wicklow National Park in June

When we traveled to Ireland in June, we packed lots of layers, rain jackets, and overall warm, practical clothes. Well, we ended up getting the warmest, sunniest 2-week streak of weather Ireland has experienced in years! While I can’t complain because we truly had wonderful weather and clear skies, it was definitely not the typical gloomy, drizzly Irish weather we were expecting. 

We ended up having to buy some new outfits for the unexpectedly warm weather and we used our swim suits much more than we thought we would with some spontaneous stops at beaches packed with locals also soaking up the perfect weather.

In retrospect, I still think we packed really well for Ireland at that time of year, and I’m not necessarily advising you pack multiple tank tops and sundresses in case of a hot spell.

Just days after we left, the temperatures dropped to their normal chilly selves and clouds and drizzles returned to the skies. We truly experienced a fluke. 

I share this with you so you don’t look at our photos and expect endless sunshine, because that was honestly not normal Irish weather in June.

Check out what our time looked like in our Ireland Road Trip video:

While sharing our Ireland trip on our Instagram stories, we received countless messages from people who live in Ireland and the UK saying how uncommon this weather was, that sometimes there’s a day or two of hot, sunny weather followed by a return to “normal”. But 2 straight weeks of this, they all assured us, was definitely not normal for Ireland.

Insider tip (for when you didn’t pack for the weather!)

If you, too, arrive in Ireland and realize the weather isn’t quite what you packed for, head to Penneys, a popular chain that truly has everything, from undergarments to outerwear to bath towels to accessories. You’ll find men’s, women’s, and children’s clothing all at super reasonable prices.

The quality is average (a.k.a. what you’d expect for a big box store selling everything for cheap), but you can find this store in most large cities (simply type “Penneys” into Google Maps to find the closest location). It comes in clutch when you need to grab something in a pinch and don’t want to spend your entire day searching (or your entire budget).

Our waiter the first night recommended Penneys after we told him we definitely didn’t pack for the heat and sun, and it was such a great rec that we wanted to pass it along so you can keep it in mind. H&M is also pretty common and another good option when you need to do a quick bit of shopping.

Ireland geography overview

Blasket Islands Ireland

The Emerald Isle is so named for a reason; thanks to the abundant rain, Ireland’s rolling hills are famous for their lush green color. You know what they say about why the grass is always greener.

The verdant plains are dotted with shimmering lochs (lakes), heathered moors, and craggy mountains. The mountains are moderate, with the highest peak of Carrantuohill in the Macgillycuddy’s Reeks range reaching 1,041 meters (3,414 feet).

Ireland is surrounded on all sides by 3,172 kilometers (1,971 miles) of rugged coastline where the Atlantic Ocean crashes against towering sea cliffs and weathered islands are sprinkled offshore.

Weather in Ireland

Connemara Ireland rain
This was the ONE rainy day we encountered on our 2-week trip in Ireland (our last day no less!). This was definitely NOT normal, as we explained in the “Our Experience” section. You’ll likely have a few rainy days.

Let’s get one thing straight right off the bat: it will most likely rain during your trip to Ireland, no matter when or where you visit. But don’t let that deter you, just make sure ya pack a rain jacket.

That said, there are some variances in precipitation across the country. The west coast gets almost twice as much rainfall as the east, since prevailing winds tend to break over the western mountain ranges.

The rainfall does also vary throughout the year, with May and June receiving the most sunshine on average.

The weather can change on a dime in Ireland and it’s not uncommon to experience rainshowers, sunny breaks, and rolling clouds all in the span of a few hours.

The good news is that the presence of the Gulf Stream means Ireland’s climate is quite mild and doesn’t typically experience extreme temperatures one way or the other. 

Winter temps rarely dip below freezing and summer generally sees highs under 21 degrees Celsius (70 degrees Fahrenheit), making for comfortable temperatures year-round.

If you enjoy festive atmospheres and cultural events, visiting Ireland during St. Patrick’s Day can be an unforgettable experience.

Best time to visit Ireland in our opinion…

Cliffs of Moher Ireland

Because Ireland doesn’t experience extreme temperatures and receives rain year-round, there isn’t really a bad time to visit.

In our opinion, the best time to visit Ireland depends on what you prefer to do. 

If you want to check off all the must-see sights and popular tourist attractions, then spring and fall offer pleasant weather with fewer crowds and slightly cheaper accommodations. We would avoid the summer months for visiting big cities and popular sights.

If hiking national parks is your goal, then the months of June through August provide the most daylight hours for exploring Ireland’s wilderness. But keep in mind that this is peak tourist season, which means higher prices and booked-up accommodations.

Winter is the rainiest, but also the least crowded season, and offers its own unique opportunities like Christmas markets and the possibility of seeing the Northern Lights.

Overall, we recommend visiting Ireland in May or September/October for a more affordable trip with fewer crowds, pleasant weather, and access to most tours and activities.
