With its famously unpredictable weather, it can be tough to decide the best time to visit Ireland.
The good news is that whatever month you decide to go, you'll have lots of things to do. With stunning scenery, cozy pubs and a great food culture, there are plenty of highlights to suit every traveler.
The warmest months from April to August offer endless hours to explore the coastline or lush, rolling green countryside. With a year-round temperate climate that rarely freezes in winter or blisters in summer, however, it’s possible to enjoy daytime outdoor activities in any month.
The end of October marks the year’s passage of mostly day into mostly night, and keeping in tune with the passing of this season is deeply rooted in the Irish DNA. This is the time of year when things slow down as ferries to the islands scale back their service and smaller restaurants and hotels close for the season. Off-season isn’t the worst time to visit Ireland, though, as there are still plenty of things to see and do during wintertime.
And don't forget, while waiting for a pint of Guinness to draw or a train to arrive, talking about weather is always a good conversation starter with locals in Ireland. Here, a week of light rain can appear in July while December can offer bright crisp days.
Here’s our guide to help you decide the perfect time to visit Ireland.
The September and October shoulder season means harvests and vibrant festivals
Along with springtime, the months of September and October can be the best time to visit Ireland to avoid crowds and save money as prices plummet. Expect long days with mild temperatures and plenty of dry spells to explore the explosion of color throughout Ireland’s national parks and forests. Even the famous Ring of Kerry, with its dramatic mountainous setting against a vivid ocean backdrop, can be navigated without a convoy of tour buses blocking the views.
Many of Ireland’s best festivals shift into gear at this time. Expect some tasty offerings like the Armagh Food and Cider Weekend or Galway’s International Oyster and Seafood Festival in September. County Cork has the monopoly on October events with the Kinsale Gourmet Festival and Guinness Jazz Festival. A sinister twist brings the month to a close with a spectacular parade at the Galway Aboo Halloween Festival, and if you're in Dublin, the hometown of Dracula’s creator, catch the Bram Stoker Festival.
The low season from November to February is the best time for a cheap stay in Ireland
For some, a ramble to a fireside pub in the local village before turning in for the night in a thatched cottage as an Atlantic gale bellows outside is the ultimate romantic getaway. For others it’s the lantern-lit, cobbled lanes of Ireland’s larger towns like Kilkenny, Limerick or Galway that capture a winter spell in Ireland. They offer good transport links to scenic locations during the day and a wide selection of restaurants and hotels offering low rates to while away the long evenings.
However, with short daylight hours, the occasional storm and icy road conditions, an independent road trip should remain on the motorways. Apart from the heavy hitting tourist attractions like the Cliffs of Moher, The Rock of Cashel, Bunratty Castle or city museums, many of the interpretive centers close for the season, while transport services scale back and remote hospitality goes into winter hibernation.
The holiday season lasts all of December in Ireland, so expect to encounter plenty of Christmas markets like Eyre Square in Galway or The Milk Market in Limerick.
March is a pricier time to visit because it's all about St Patrick's Day
Let’s face it – St Patrick owns March with his very own day on March 17. You should be aware that some locals are a little tetchy about his name, so resist the urge to retitle him Patty or Paddy. It’s also the month when tourism and transport stretch wide awake from their winter respite. While weather conditions are still unsettled, the thermometer edges up to 10°C (50°F) and days are much lighter.
The St Patrick’s Day Parade takes center stage in Dublin, Limerick and Cork with floats, jigs, reels and green beer or milkshakes to garnish a diet of sentimental shenanigans and silliness. And yes, expect price hikes in hotels for that week. However, country parades like the little County Clare procession in Doolin offer a satirical take on the larger events and can be equally rewarding. The global phenomenon of lighting sites up in green is predictably rampant in Ireland and can create an atmospheric glow against the limestone render of medieval buildings.
The April to June shoulder season is the best time for golf, flowers and driving along the coast
With temperatures an average high of 18°C (64°F) and prices that haven’t maxed out yet, this is the best time to take a road trip along Ireland’s magnificent Wild Atlantic Way. It’s a 1,500-mile, sign-posted west coast route that connects Cork in the south to Donegal in the north. It’s also the best time to visit Ireland for golf; play on links near charming villages, white sandy beaches, coves, castles teetering on cliff tops and vibrant towns like Westport or Sligo.
Blossoms burst into life throughout the country in these months, so visit the garden county, Wicklow, to catch bluebell season at Powerscourt or Glendalough in April. County Clare’s Burren in Bloom festival in May is a great way to see rare species in a spectacular moonscape setting. It can also be the best time to visit Dublin as June kicks off with the Flowers in Bloom Festival shortly before the city hosts Bloomsday on June 16, a celebration of writer James Joyce’s blossoming of a different nature. The festivities are followed a couple of weeks later with a sea of rainbow flags with the country’s biggest LGBTQ+ Pride Festival.
The peak summer season of July and August comes with higher temperatures and crowds
First the bad news: all Irish schools and colleges are out for summer, so in July and August you’re competing with the home market when it comes to accommodations, food, car hire and visitor attractions. That means higher prices and packed beaches (when the sun is out). Last-minute bookings at hotels and restaurants in popular locales are risky.
However, it's an excellent time to stay on an island like the Arans or Inishbofin, where bikes are the best form of transport. Alternatively, Ireland’s lesser seen Midlands are filled with medieval fortresses, blue river trails and quaint villages – and they’re crowd-free. There’s no better way to explore the area than hiring a boat on the Shannon, the longest river in Ireland, to visit off-radar places like the pretty town of Killaloe, the very Instagrammable high crosses at Clonmacnoise or Sean’s Bar, the oldest pub in Ireland. Boat hire means setting your own independent itinerary, and it offers excellent value for money as you’ll sleep on board.
