May is when the weather, which has been warming for the last few months, shows the landscapes of Ireland in full color as average daily high temperatures of 59°F/15°C arrive and the countryside blooms with flowers and birdlife. Along with April, this is arguably the best month to enjoy Ireland, with the year’s lowest rainfall to accompany the sun and with the crowds that arrive in the high season from June to August still absent in most places.
Ireland in May: A Comprehensive Travel Guide
## Weather in Ireland
Ireland, while relatively small in size, offers a captivating blend of landscapes and experiences. However, its geographical dimensions mean that distinct regional weather patterns are not particularly pronounced. Generally speaking, the month of May often stands out as one of the most pleasant times of the year to visit, weather-wise. During this month, the average daily high temperatures can reach a comfortable 59°F (15°C). May also boasts the highest daily average amounts of sunshine, providing ample opportunity for outdoor exploration. Furthermore, the monthly rainfall is typically at its lowest point during the year, making it an ideal time for travelers seeking drier conditions.
### Killarney & Southwest Ireland: A Springtime Paradise
May truly showcases the loveliness of Killarney and Southwest Ireland. Spring is in full bloom, vibrantly coloring the landscape from the meticulously maintained city parks to the rugged mountain slopes. The abundance of sunshine further enhances the region’s appeal, with more daylight hours than any other time of year, except for April and June. Average rainfall and the average number of rainy days are significantly reduced, with May experiencing the fewest days with precipitation, averaging around 20 days. As in other regions of Ireland during this time, average daily high temperatures climb to a pleasant 59°F (15°C), creating ideal conditions for exploring the great outdoors.
### Dublin & Eastern Ireland: Sunshine and Seaside Breezes
In Dublin and along the eastern seaboard, May is tied for the driest period of the entire year. Dublin experiences an average monthly rainfall of just 1.96 inches (50 mm), a remarkably low figure for Ireland. Daily hours of sunshine reach their peak at six hours per day, a maximum that persists until August, providing ample opportunity to soak up the sun’s rays. However, it is important to note that water temperatures remain relatively low, comparable to January and lower than any subsequent month of the year. The water simply hasn’t had enough time to warm up sufficiently, so swimming may not be the most appealing activity during this time.
### Belfast & Northern Ireland: A Month of Transformation
Belfast and Northern Ireland undergo significant weather changes in May. Average daily temperatures rise to match those of other regions, reaching a comfortable 59°F (15°C). However, average lows remain cooler, at around 43°F (6°C), suggesting the need for layered clothing, especially in the evenings. Rainfall averages 1.96 inches (50 mm) for the month, representing its annual low, offering a welcome respite from the wetter months.
## Crowds & Costs: Navigating the Tourist Season
The allure of Ireland’s fair weather in May is no secret. Many travelers arrive seeking favorable conditions without the overwhelming crowds of the peak summer months. While visitor numbers do increase compared to other times of the year, they remain lower than the summer rush when families typically take their holidays. Consequently, prices for accommodation and some tours and activities are generally lower than high-season rates. However, in more popular areas, it is still advisable to book accommodations and activities well in advance to secure your preferred choices.
## Where to Go: Unveiling Ireland’s Treasures
### Killarney & Southwest Ireland: An Outdoor Enthusiast’s Paradise
In short, the entire region beckons! Ireland’s dry, sunny weather in May encourages exploration of the Great Outdoors, showcasing what Ireland does best. In this, the country’s most remote region, there is more on offer than ever before. Co. Kerry serves as an excellent starting point, with incredible mountain and coastal hiking opportunities along its legendary southwest peninsulas, such as the Kerry Way (Iveragh Peninsula), the Dingle Way (Dingle Peninsula), and the Beara Way (Beara Peninsula, shared with Co. Cork).
Embark on a boat trip to the rocky Skellig Islands near Dingle or, even better, to the otherworldly and traditional Aran Islands near Galway. Afterwards, make a stop in Galway itself, a vibrant city hosting a couple of festivals during this month. Venture up to Donegal to experience the dramatic cliffs at Slieve League, some of the country’s highest and most breathtaking.
### Dublin & Eastern Ireland: Escaping the City
While Dublin offers its own unique charm, consider venturing into the countryside this month. South of Dublin, the most appealing option is the Wicklow Way, offering some of the most delightful hiking in the entire region. This area boasts a top-drawer selection of attractions, including chocolate-box villages like Enniskerry, crashing waterfalls such as Powerscourt Waterfall on the enchanting Powerscourt Estate, wooded hills, and monastic ruins like Glendalough Abbey.
Gorgeous sandy beaches line the coast here. Some, like Loughshinney, are located within Co. Dublin and are easily accessible from the city. Additionally, consider a trip inland to attend some memorable festivals this month. Visit historic Kilkenny for roots music or Co. Westmeath for electronic music.
### Belfast & Northern Ireland: Coastal Wonders and Mythical Isles
In May, it’s time to focus on outdoor activities in Belfast & Northern Ireland. Begin with the Causeway Coast, home to the UNESCO-listed Giant’s Causeway, a breathtaking expanse of thousands of interconnecting basalt columns, making for one of the most spectacular coastal attractions imaginable.
Alternatively, explore the mythical Rathlin Island, where exiled Scottish leader Robert the Bruce once sought refuge. Or experience the country’s northernmost point with a hike to Malin Head. For a longer hiking adventure, there is nothing more epic than the Ulster Way, a 636-mile (1,024-km) loop that traverses almost all of Northern Ireland and is one of the UK’s longest and most beautiful hiking routes.
## What to Do: Immersing Yourself in Irish Experiences
### Killarney & Southwestern Ireland: Hiking, Cycling, and Water Adventures
Hiking should be a primary focus of any May itinerary in Killarney & Southwestern Ireland. Explore hikes like the Dingle Way mentioned above, or simply wander along the Wild Atlantic Way, stopping at any remote location that captures your interest. Cycling is particularly enjoyable in May before the roads become too crowded.
Further north in this region, the snaking lake and surrounding emerald-green hills by Lough Gill inspired WB Yeats and are likely to captivate you as well. Hike around the lake or go kayaking on its tranquil waters. Waves and swells are still ideal for surfing in May, although this is the last month until autumn when conditions are favorable. The Sligo and Donegal areas are particularly renowned for surfing.
Sligo also boasts the highest concentration of megalithic monuments in Ireland. A walk to see some of these monuments, such as Carrowkeel and Carrowmore, is an unforgettable experience. These ancient monuments predate the Pyramids at Giza!
### Dublin & Eastern Ireland: Walking, Beaches, and Ancient History
Lace up your hiking boots for some wonderful walking on the Wicklow Way, which showcases the very best of Eastern Ireland and begins in Dublin’s southern suburbs. Or explore some of the region’s stunning sandy beaches, which line the entire eastern coast and are especially inviting in the improved, sunnier weather.
Remember that this region is known as “Ireland’s Ancient East.” For a great insight into Ireland’s rich history without spending too much time indoors, visit the Irish National Heritage Park near Wicklow. This park takes you on a journey through 9,000 years of the country’s past in a magical open-air setting. Or explore spectacular ancient sites such as the huge circular megalithic tomb of Newgrange, in Co. Meath.
### Belfast & Northern Ireland: Epic Hikes and Coastal Wonders
Hiking is the activity that best showcases the incredible beauty of Northern Ireland in May. The Causeway Coast is undeniably dramatic, but despite the attention given to the Giant’s Causeway, the hike that best reveals this region’s fantastic scenery is the 636-mile (1,024-km) Ulster Way. This route takes walkers to high mountains, wild forests, and serene lakes, as well as the breathtaking coastline.
For a shorter but nevertheless thrilling walk, dare to cross the vertiginous Carrick-a-Rede Rope Bridge, which connects the wild island of Carrickarede to the mainland. Or try spotting locations from the blockbuster TV series “Game of Thrones,” which has significantly boosted Northern Ireland’s travel industry. Sights to check out include the Downhill Strand in Co. Derry and Tollymore Forest Park in Co. Down.
