park, pints, and perfect sunsets

Summer in Dublin is the perfect mix of sunshine (sometimes), festivals (always), and pints (essential). Whether you’re sightseeing in the Wicklow Mountains, relaxing at St. Stephen’s Green, or fighting the urge to jump in the Irish Sea, the city comes alive with endless things to do. Look into our best time to visit Dublin guide for your year round itinerary. But for summer, this is your ultimate guide to making the most of Dublin’s sunniest(ish) season, so let’s dive deep into some great craic!

summer weather in Dublin

In Dublin, don’t expect the same type of weather you would get in Cancún on a summer's day - unfortunately. But, expect a mix of sunshine, light showers, and the occasional “four seasons in one day” moment! You can expect the temperatures to hang around a comfy 15-20°C, making it perfect for those park walks and pub hopping bouts. All you’ll need are your sunnies and a light jacket, because when the sun does shine, you won’t want to miss it!

Dublin day trips

The beautiful Cliffs of Moher near Dublin in Ireland

Thinking of what to do in Dublin, without staying in Dublin? Trust us, there’s bunches to explore in the summer sun outside the city. If you want something that will have your jaw drop, the Cliffs of Moher is a solid choice. Think a slight breeze, stunning cliffs, and unimaginable beach views only 3 hours away by bus.

To quench that thirst for mountain scenery, the Wicklow Mountains are another must-visit destination. Only being an hour away, the fresh air and few tourists make these rolling green hills even more enjoyable. The Wicklow Mountains, alongside their tranquil lakes and ancient ruins, make for a peaceful wander about - and maybe a few smug nature snaps.

For something a bit more regal (and a lot less breezy), Kilkenny Castle delivers the royal vibes, charming streets, and pretty gardens from over 800 years. And after all the sight seeing the castle has to offer, of course there’s a pint waiting for you in town after. Don’t skip out on the town itself: full of medieval streets, cosy pubs, and local shops.

green escapes in Dublin

park in Dublin during the summer

When the sun shows itself in Dublin (rare, but glorious), the parks fill up fast - and for good reason. Phoenix Park, you know… the huge one, should be your first stop. You’ll be able to mosey around and find wild deer, the president’s house, and enough space to not bump into another person’s picnic.

Still around the city lies St. Stephen’s Green, a mere 8 minute walk from your cosy citizenM Dublin St. Patrick’s hotel. This park is the perfect hideout for people-watching , duck-feeding, or giving your feet a break after a shopping spree. Pick up a couple snacks, some friends, and soak up the calmness (until the seagulls show up).

Looking for a park tucked away from the hustle and bustle? Iveagh Gardens has those secret garden vibes you’re looking for with hidden fountains and way fewer crowds. So basically, Iveagh Gardens is Dublin’s “worst-kept” best-kept secret if you know what we mean.

festivals worth enjoying in Dublin

Summer in Dublin means one thing - and that’s festival season. You don’t want to miss out on festival season, the city does not hold back. Kick things off in May 2025 at Forbidden Fruit Festival in the Kilmainham neighbourhood of Dublin. Bumping beats are to be expected from big-name DJs, indie musical gems, and a crowd that knows how to party. Half music festival, half fashion show, and 100% dancing.

Next up in June is the beloved Pride Festival 2025 in Dublin. Parades, parties, and glitter fill the streets (and maybe your shoes) when celebrating Pride. Don’t forget your rainbow garb and your loving spirit at this festival. It’s loud, proud, and full of feel-good vibes.

Then there's the Longitude Festival at the end of June, beginning of July hosted in Marlay Park. Some of the most notable artists from genres of rap, techno, and house music will be performing - perfect for those wanting to mosh or jump on someone’s shoulders. Bring your best festival energy, Dublin is ready for you.

beach days, the Irish way

Sandymount Beach in Dublin, Ireland on a sunny and clear day

Each beach in every country is different, so why not head on out and experience the Irish beaches just a quick bus away! The closest call, Sandymount Beach, is perfect for a breezy stroll with views of the iconic Poolbeg Chimneys. We don’t recommend taking a swim (unless you’re into cold plunges) but you are more than welcome to paddle out if you want some action.

If you are hankering for a swim, Portmarnock Beach, aka the Velvet Strand, is your beach. This beach is long and wide, harboring locals, seagulls, and an occasional brave kite surfer. Grab a 99 (soft-serve ice cream for non-locals) or take a nap between dips, either way you will enjoy the coastal calm.

Stretching along Bull Island is Dollymount Strand, or ‘Dollyer’ if you want to sound in-the-know. This strand is a mini island off the coast of east Ireland. Expect dramatic skies, a steady breeze, and plenty of green space to play football, fly a kite, or pretend you’re in an indie film. Visit this Dublin favourite strand for a gorgeous city skyline view and a picture-worthy coastline.

must-see museums

Museums in Dublin don’t just offer history lessons. Learning here is better with a beer in hand, right? If this is what you’re looking for, stroll on over to the Guinness Storehouse. Spread across 7 floors, this storehouse immerses the visitors in the beer-making and tasting process, ending the day with a rooftop view and the perfect pour.

Next up on the list is one of the most famous museums in the country, the Little Museum of Dublin. This small but mighty museum is jam packed inside a Georgian townhouse, telling the story of Dublin through quirky artifacts, old advertisements, and local tales told throughout the city. It’s like stepping into Dublin’s living room - cosy, colourful, and full of character!

If you’re looking for a museum with a bit more of Dublin’s past, the Kilmainham Gaol Museum is for you. This museum sits within a former prison-turned-museum, walking you through Ireland’s struggle for independence. The Kilmainham Gaol Museum is one of the city’s most unforgettable spots - and for a very good reason.
