Why May Matters for Travelers to Ireland

Choosing the right month to visit Ireland can make or break your trip. While Ireland is stunning year-round, each season has unique challenges and opportunities. May stands out for several reasons:

1. Milder Weather – Average temperatures range from 9°C to 15°C (48°F–59°F). While not hot, it’s a comfortable time for exploring.
2. Longer Days – With daylight stretching up to 16 hours by the end of May, you’ll have plenty of time for sightseeing.
3. Fewer Crowds than Summer – Peak tourist season hits in June, July, and August. May offers a sweet spot of good weather without overwhelming crowds.
4. Nature in Bloom – Rhododendrons, bluebells, and wildflowers create colorful landscapes, making national parks and gardens especially enchanting.

From a practical standpoint, May provides a balance between affordability and enjoyment. Flight prices and accommodation rates often rise in the summer months, so traveling in May can help stretch your budget.

Weather in Ireland in May

Average Conditions

May is one of the driest months in Ireland, though “dry” is relative — light rain showers are still common.

A waterproof jacket and sturdy shoes made a huge difference.

Events and Festivals in May

Ireland in May is rich with cultural and seasonal events. If you time your trip right, you can enjoy local traditions alongside your sightseeing.

1. May Day (Bealtaine) – Celebrated on May 1st, this marks the beginning of summer in the ancient Celtic calendar. In some rural areas, you’ll still find Maypole dancing or floral decorations.
2. Bealtaine Festival – A nationwide arts festival celebrating creativity among older generations, with music, theater, and exhibitions.
3. Dublin Dance Festival – International dancers and choreographers gather in Dublin, usually mid-to-late May.
4. Galway Early Music Festival – Showcasing medieval and Renaissance music, often featuring authentic instruments and costumes.
5. Bloom in the Park (Dublin) – Ireland’s largest gardening festival held in Phoenix Park, typically in late May. It’s a vibrant event full of flowers, food stalls, and family-friendly activities.

I attended Bloom a few years ago, and it was a wonderful mix of Irish gardening culture and delicious local food. Even if you’re not a gardener, it’s a fantastic way to experience Irish creativity and outdoor life.

Top Places to Visit in May

1. Dublin

Ireland’s capital is always bustling, but in May, the warmer weather makes it easier to enjoy outdoor attractions like:

• Trinity College & The Book of Kells
• Dublin Castle
• St. Stephen’s Green in full bloom
• Temple Bar for live music and a lively atmosphere

A walk along the River Liffey in May feels refreshing, especially when the evenings are still light past 9 p.m.

2. Galway

A vibrant city on the west coast, Galway is known for its artsy vibe and colorful streets. In May, you can enjoy open-air performances, weekend markets, and easy access to Connemara National Park.

3. Cliffs of Moher

Ireland’s most famous cliffs are stunning any time of year, but May’s longer daylight hours allow for less rushed visits. The Atlantic winds can still be strong, so pack layers.

4. Killarney & The Ring of Kerry

Spring makes Killarney National Park especially magical with lush greenery and wildlife activity. The Ring of Kerry is less crowded in May, making the scenic drive even more enjoyable.

5. Wild Atlantic Way

The Wild Atlantic Way, stretching 2,500 km along Ireland’s west coast, is at its best in spring. May’s relatively mild weather and blooming landscapes make road-tripping particularly rewarding.

6. Northern Ireland (Belfast & Giant’s Causeway)

If you extend your trip north, May is perfect for visiting Belfast and the UNESCO World Heritage-listed Giant’s Causeway. The hexagonal rock formations are less busy compared to the summer season.
