If you’re looking to experience a small group tour of Ireland in the summertime and want to know what to expect, you’re in the right place. This article covers everything you need to know about this season on the Emerald Isle.

When Is Ireland’s Summer?

Let’s start from the beginning: when is summer in Ireland? It kicks off in June and runs until August. However, like all Irish seasons, the weather can be unpredictable – sunshine one moment, rain the next. So, it’s not always obvious when summer arrives in Ireland.

That said, longer daylight hours, lush green landscapes, and milder temperatures are all clear signs that summer is in full swing, even if those occasional rain showers are never far behind!

Ireland Summer Weather: What to Expect

The summer holidays in Ireland typically bring the country’s brightest, warmest days, making it a popular time for visitors. Still, Irish weather is known for its unpredictability, so don’t be surprised if you experience all four seasons in a single day! It’s all part of the charm. 

Here’s what to expect during each of the summer months in Ireland. 

What is the Weather Like in Ireland in June?

The temperatures in Ireland in June tend to be very pleasant, with daytime highs of 18°C (64°F) and lows of 11°C (52°F). 

One of the best things about June weather in Ireland is that this is when you get the longest days of all of the summer months, with daylight hours stretching to a glorious 17 hours. This means you get plenty of time to go out and discover the island’s breathtaking landscapes and outdoor scenery in June.

What is the Weather Like in Ireland in July?

July marks the heart of summer in Ireland, and it’s typically the warmest month of the year. You can expect daytime temperatures to hover around 19-20°C (66-68°F), with nighttime temperatures rarely dropping below 12°C (54°F).

You’re also treated to wonderfully long daylight hours in July, with the sun rising before 5 am and not setting until nearly 10 pm. 

As a whole, July tends to be one of the island’s drier months. While you’ll likely still catch a shower or two during your stay, they are often brief at this time of year.

What is the Weather Like in Ireland in August?

August is the final month of summer in Ireland. The daylight hours remain long, with around 15 hours of sunlight early in the month, and 14 hours towards the end, still giving you plenty of time to go out and explore the country’s beautiful outdoors. 

The weather in August stays generally mild and pleasant, with average temperatures ranging from 11°C to 19°C (52-66°F). As the month goes on, the occasional rainy day becomes a bit more common, as the country ushers into its autumn season.

The Best Places to Visit in Ireland in Summer

Planning a summer break to Ireland and wondering where to go? We’ve lined up the top destinations to visit on the Emerald Isle during this time of year. 

Aran Islands, Co. Galway

Off the coast of Galway, the Aran Islands are a bit of a hidden gem, despite being one of the top places to visit in Ireland in summer. The warmer months bring calmer seas and longer daylight hours, making it the perfect time to explore these remote and beautiful islands. 

These three wild islands, Inishmore, Inishmaan, and Inisheer, are extremely remote and removed from day-to-day modern life, offering a fascinating snapshot into the country’s past.

The landscapes are rugged and unspoilt, with lush green countryside, limestone rock and ancient stone walls. As you explore, you’ll come across ancient forts dating back to the Bronze and Iron Ages, along with cliffs that plunge dramatically into the Atlantic Ocean.

Causeway Coast, Co. Antrim

For dramatic shorelines and amazing beaches in Ireland this Summer, head to the Causeway Coast. 

Located in Northern Ireland, this extraordinary stretch of coastline is known for its breathtaking views, quiet beaches, and the famous Giant’s Causeway, a 60-million-year-old shoreline lined with fascinating hexagonal basalt stones, said to have been formed by giants.

You can uncover local legends, soak up breathtaking coastal views, and enjoy scenic hiking trails and forest paths before relaxing in the summer sun on a quiet beach. With long daylight hours and mild weather, summer is the perfect time to visit the Causeway Coast.

Slieve League Cliffs, Co. Donegal

Soaring nearly 2,000 feet above the wild Atlantic Ocean, County Donegal’s Slieve League Cliffs are some of the highest sea cliffs in Europe and offer some of the most incredible views in Ireland at any time of year, but especially during the summer months.

Whether you are planning to go hiking or simply take in the views from the cliffs’ various points, the clear summer skies provide excellent visibility so you can really soak up the fantastic scenery in all of its glory. 

Another benefit to visiting during June, July or August is that the hills come alive with wildflowers. The vibrant flowers create a stunning contrast against the grey cliffs and emerald hillsides, creating the most beautiful setting for you to explore. 

The Slieve League Cliffs have lots of different walking trails to choose from that extend across all ability levels, from easy strolls to adventurous treks, each promising amazing vistas over Donegal Bay. 

Killarney National Park, Co. Kerry

Summer in Ireland wouldn’t be complete without exploring Killarney National Park. This UNESCO-protected reserve comes alive during the warmer months, with its pristine lakes, ancient woodlands, and majestic mountains transforming into a nature-lover’s paradise.

Hop on a traditional jaunting car for a horse-and-carriage ride through the park, take a leisurely cruise across the Lakes of Killarney, or discover historic sites like Ross Castle and Muckross House and Gardens, all in the mild Ireland summer temperatures.

The park’s diverse ecosystems also support interesting and rare wildlife, including the native red deer, which are more active and visible during summer. This is a great time for a vacation to Ireland, especially Killarney National Park, for animal lovers.

This is also a great time of year to go hiking or rent a bike to explore the park’s well-marked trails, or simply sit down and enjoy a peaceful lakeside picnic.

The Best Things to Do in Ireland in Summer

If you’re wondering what to do in Ireland in Summer, we’ve shared some of our top recommendations below. 

Tick Off the Wild Atlantic Way, Co. Donegal 

Hands down, one of the best things to do in Ireland in the summer is to tick off the Wild Atlantic Way. The world’s longest defined coastal route, this 2,500 kilometre-long adventure leads you through many of the country’s most legendary sights and landmarks.

From the enchanting Cliffs of Moher and the wild landscapes of Donegal, to the breathtaking Causeway Coast, and the charming medieval streets of Kilkenny, the Wild Atlantic Way offers the full Irish experience, packing some of the most beautiful spots on the island into one adventure-filled experience. 

Summer is one of the best times of year to go on a road trip along the Wild Atlantic Way, as you get the best weather to discover all of the stunning landscapes, outdoor beauty and natural landmarks along the route. 

Kiss The Blarney Stone, Co. Cork

Kissing the Blarney Stone is one of Ireland’s most iconic traditions, and summer is the best season to do it. The famous stone sits in Blarney Castle itself, which dates back to 1210 CE, and the castle grounds flourish with colourful flowers at this time of year, looking straight out of a fairy tale.

It is said that planting a smooch on this famous slab of limestone grants the “gift of the gab,” i.e. the ability to speak with charm, wit and eloquence. 

According to legend, Cormac Laidir MacCarthy, the 15th-century lord who rebuilt the castle, struggled with a lawsuit. So he sought help from the goddess Clíodhna. She told him to kiss the first stone he came across, and after doing so, he found himself speaking so persuasively in court that he won the case. 

That very stone was later built into the castle and became known as The Blarney Stone. But that’s just one version of events. Other legends say the prophet Jeremiah brought the stone to Ireland, while another tells of a witch, saved from drowning, who revealed its magical powers to King Cormac MacCarthy of Munster. The stories go on! 

Whichever version you believe, one thing’s for sure: a kiss on the Blarney Stone is a legendary experience and one of the top things to do on a summer holiday in Ireland
