There’s something magical about summer in Ireland. Long golden evenings, green landscapes glowing in the sun, and an unmistakable sense of energy in the air. It’s no wonder that June through August is the most popular time to explore our Emerald Isle.
With this in mind, it occurred to all of us here at Overland that we’ve never written a guide dedicated specifically to our beautiful island during its warmest, busiest month. So here we are! We’ll hopefully help you learn more about Ireland and perhaps inspire you to start planning your next Ireland trip.
If anything we say stirs your wanderlust and you’d like to learn more, check out our small group tours of Ireland and our more personalized private guided tours of Ireland. For now, though, let’s find out more about Ireland in summer!
The Temperature in Ireland During Summer
Although we are famed for experiencing all four seasons in one day, summer also blesses us with the best weather of the year. It’s when conditions are at their most predictable and pleasant. Daytime temperatures typically range between 60 to 70°F (15 to 21°C), though you’ll occasionally get a glorious spell where it climbs to 77°F (25°C).
The weather is mild rather than hot, which makes it ideal for exploring. You can hike along the Cliffs of Moher, wander the streets of Galway, or cycle through Killarney National Park without ever breaking too much of a sweat. That said, always pack for variety: sunscreen, sunglasses, and a rain jacket will all come in handy at some point!
The sea also warms up to around 60 to 65°F (16 to 18°C), inviting locals and visitors alike to dive into the Atlantic. Sea swimming has become a national obsession; you’ll spot groups of early risers braving the waves from Dingle to Donegal. Join them if you’re feeling brave, or simply enjoy the view with a hot coffee in hand.
You’ll even find natural swimmers going for their daily dip in the sea right through December and January! We’re not sure if they are adding or subtracting from their life expectancy!
Before we jump to the next section, let us also recommend our blog What is the Best Time of Year to Visit Ireland. It’s filled with local tips and insights for anyone unsure of when to time their trip, so be sure to read it when you have finished here.
The Atmosphere in Ireland During Summer
The atmosphere in Ireland during the summer months is electric! There’s a change in the air that’s hard to describe until you experience it. Towns and villages buzz with energy as shopfronts get a fresh coat of paint and locals prepare to welcome guests from near and far with their classic ‘Céad Míle Fáilte’ (a hundred thousand welcomes). Oh, by the way, we can help you learn more Irish before your visit, too!
Street performers line the streets entertaining the masses, which means that you can’t walk 10 meters in Galway city without encountering some talented soul dancing, singing, or putting on a show for passersby.
Revelers are drawn to the ‘Craic’ (fun) in the pubs during the summer, with nightly traditional Irish music sessions and good banter from friendly locals looking to share their stories. But be warned: we like to embellish a little when telling tales! I think we get it from kissing the Blarney Stone!
Summer brings a general sense of cheer that’s contagious. The longer daylight hours only add to the magic. With sunset as late as 10:30 or 11 p.m. around the solstice, there’s time to explore, dine, and soak up the atmosphere long after dinner.
Ireland’s Landscape and Wildlife in Summer
The phrase “40 shades of green” really makes sense in summer! Rolling fields, rugged coastlines, and national parks are all in full bloom, offering some of the most photogenic scenery in Europe. It’s the best time of year for walking, cycling, and outdoor adventures, and the mild temperatures make it all the more enjoyable.
Nature lovers will be spoiled, too, especially as our little winged friends come out to greet our guests! Puffins return to Skellig Michael between May and early August, creating one of Ireland’s most unforgettable wildlife experiences (you can visit on our Ireland to Island 7-Day Tour). In the countryside, lambs and calves graze under blue skies, and the hedgerows overflow with wildflowers.
And speaking of lambs, you can even give one a cuddle on the Slea Head drive! They are adorable and will surely melt your heart. When it comes to flora and fauna, summer sees Ireland at its most vibrant.
Long Summer Evenings in Ireland
One of the true highlights of an Irish summer is the long evening light. Daylight hours peak on the 21st June, when there will be daylight right up until 11 pm, giving you extra hours to explore and enjoy our country. Towns and villages come alive in a relaxed, almost magical atmosphere — pubs spill music onto the streets, street performers entertain, and the countryside glows in soft, golden light.
But it’s not just June that offers extended hours for experiencing the best of Ireland! In July, evenings remain long, with sunset around 10 pm, and even in August, daylight stretches until about 9:30 pm, offering plenty of time to make the most of your day.
These long evenings are perfect for strolls along coastal paths, casual exploration of charming towns, or enjoying an outdoor meal while watching the sun dip behind hills or harbors. It’s a wonderful time to capture photographs, discover hidden corners, or simply soak up the energy and charm that make summer in Ireland unforgettable.
Longer daylight hours also make navigating Ireland’s roads safer, especially for first-time drivers from overseas.
Dining Al-Fresco in Ireland
Outdoor dining has truly become part of Irish life. While we’ve always loved fish and chips by the sea, the past few years have seen a huge rise in food trucks, pop-up eateries, and patio dining across the country.
Grab oysters by the harbor in Galway, enjoy a seafood platter overlooking Dingle Bay, or stop for a fresh coffee and home-baked treat at a roadside café. Ireland’s food scene is now one of the most exciting in Europe, with an emphasis on local ingredients and creative flair. Check out our Gastronomic Guide to Ireland if you’re hungry for more!
And yes, that bag of chips by the sea still tastes best when eaten outdoors, watching the fishing boats bob in the harbor!
Summer Festivals in Ireland
Ireland knows how to throw a good party, and summer is when the festivals come thick and fast. From world-class music and arts to food, sailing, and even matchmaking, there’s something happening almost every weekend.
Some of our favorites include:
- Galway International Arts Festival (July): Theatre, music, and creativity fill the streets of Galway for two unforgettable weeks.
- Cruinniú na mBád, Kinvara (August): Watch the traditional Galway Hooker sailing boats race across the bay in this unique maritime celebration.
- Taste of Dublin (June): The capital’s best chefs, restaurants, and producers come together in Iveagh Gardens for a gourmet experience.
- Electric Picnic (August/September): Ireland’s biggest music and arts festival in County Laois, with global acts and laid-back vibes.
- Lisdoonvarna Matchmakers Festival (September): Ireland’s quirkiest celebration of love and laughter in the heart of County Clare.
- Galway International Oyster Festival (late September): While technically nudging the limits of summer, this famous festival marks the start of the native oyster season. Enjoy tasting competitions, live music, and the city’s lively harbor atmosphere — a true feast for the senses.
Small boutique music and arts festivals spring up all over Ireland during the summer season with local and international acts. Some are more unusual than others. A great example is the Puck Fair in Kerry, where they crown the goat as king! This oldest fair in Ireland sees the town celebrate the goat for three days with music and dance before returning him to the wild!

What to Pack for an Irish Summer
Ireland’s summer weather is kind with some unpredictability, so smart packing is key. While there’s no one-size-fits-all packing list, some of the essentials we recommend include:
- Light layers (T-shirts, long sleeves, and a warm jumper)
- A waterproof jacket
- Comfortable walking shoes
- Sunglasses, sunscreen, and a hat
- A reusable water bottle for your adventures
This is only an introduction to your packing list. Check out our blog What to Pack on a Trip to Ireland to find out more!
When to Visit Ireland: Early or Late Summer?
Still wondering when to time your trip? Here’s a quick recap of what you can expect from the different stages of summer:
- June: Longest days of the year and quieter crowds before school holidays start.
- July: Lush landscapes and lively local events; peak energy everywhere you go, but not as busy as you might think.
- August: Festival season and warm seas for swimming. Expect more visitors, but also the best atmosphere.
Each month offers something special, so you’re guaranteed an unforgettable experience whenever you decide to travel!
