July is a sunny and comparatively dry month to visit Ireland. Water temperatures reach their annual maximum, increasing the temptation of activities like kayaking, while the warmest weather of the year makes hiking and cycling very popular now. This is the month when there are school holidays, and is accordingly one of Ireland's busiest periods.


Ireland is not a large enough country to have distinct regional weather patterns. Generally speaking, July has some of the most appealing weather of the year in Ireland, with the highest average high temperatures of the year, plenty of sunshine, and comparatively little rain. Water temperatures are around their highest of the year now, too, although 57°F (14°C) may not be enough for some!

Killarney & Southwestern Ireland

July vibrantly colors the landscape with flowers, plant life, and birdlife from city parks to mountain slopes. Those warm temperatures help: this is the warmest weather of the year in Killarney, with average highs of 64°F (18°C).  The average rainfall is low, too: July is one of only three months in the Killarney area where monthly rainfall is 3 inches (75 mm) or below.

Seawater temperatures are almost at their annual maximum of 61°F (16°C). Throughout the month, this region actually becomes marginally cooler than in the north and east of the country.

Dublin & Eastern Ireland

July is hot in this region, by Irish standards: averages of 66°F (19°C) highs and 53.6°F (12°C) lows. Rainfall is as low as it gets at any time of the year: just 2 inches (50 mm) are expected to fall in Dublin this month.

Belfast & Northern Ireland

July is a hot month in this region too, with averages of 66°F (19°C) highs and 52°F (11°C) lows. Hours of sunshine per day are stable (around 4). But it is by no means the driest month in Belfast, with 2.75 inches (70 mm) of rain expected.

Crowds & Costs

This month is the high season in Ireland. Although it does not necessarily coincide with the best weather, it coincides with when most people take their holidays; and so costs reach their maximum for the year, where accommodation and some activities are concerned. Many schools have now gone on summer holidays, and so families will travel more in July. Be sure to book your accommodation in advance this month, along with any tours you want to take.

Where to Go

Killarney & Southwestern Ireland

Ireland's fairly dry, sunny July weather coaxes you out to explore the outdoors and in this part of Ireland, the country's most remote, there is plenty that should be on your radar. Co. Kerry is a good starting point, with fabulous mountain and coastal hiking on its legendary southwest peninsulas, such as the Kerry Way (Iveragh Peninsula), Dingle Way (Dingle Peninsula), or Beara Way (Beara Peninsula, shared with Co. Cork).

Take a boat trip across to the rocky Skellig Islands near Dingle or, better yet, to the otherworldly and traditional Aran Islands near Galway. See this article for more on the Aran Islands. Make your city stop off in Galway this month, in the throes of a fantastic fortnight-long performing arts festival, or head up the Wild Atlantic Way to Co. Donegal where another brilliant arts festival, the Earagail Arts Festival, is happening. 

Dublin & Eastern Ireland

If festivals are your thing, linger in Dublin for the Longitude Festival at the beginning of the month, and then head out into the countryside. Here, the most obvious choice south of Dublin is the Wicklow Way for some of the most delightful hiking in the whole region and a top drawer selection of the very best things to do.

Sandy beaches line the eastern coastline; some, like Loughshinney, are located within Co. Dublin and are within an easy drive of the city while others, like the divine Rosslare Strand, are in sight of where the ferry from Wales arrives.

Historic Kildare throws another of its many festivals this month (see below), and makes this town, a day trip from Dublin, another interesting destination.

Belfast & Northern Ireland

Start exploring this region's phenomenal nature with the essential trip to the Causeway Coast, where the Unesco-listed Giant's Causeway, a swathe of thousands of interconnecting basalt columns, makes for one of the most spectacular coastal attractions you could ever hope to see.

Otherwise, try an exploration of Rathlin Island, where exiled Scottish leader Robert the Bruce once took refuge, or experience the country's northernmost point with a hike to Malin Head. For a longer hike, there is nothing more epic than the Ulster Way, a 636-mile (1,024-km) loop passing through almost all of Northern Ireland and one of the UK's longest and loveliest hiking routes.

Try the Lough Bradan-Gortin or the Gortin-Moneyneany sections for some of the best vistas of the whole walk, and stretches that go through Northern Ireland's biggest mountains, the Sperrin Mountains. See here for an itinerary taking in Belfast and Northern Ireland, as well as Dublin.

What to Do

Killarney & Southwestern Ireland

All outdoor activities are great in July. For starters, checking out and perhaps swimming at some of the country's very best sandy beaches lacing the many southwestern peninsulas is a wonderful activity: try Keem Bay on Achill Island, Co, Mayo, or Coumeenole Beach near Dunquin in Co. Kerry. See here for a tour of Kerry that visits Coumeenole Beach.

Then there's the hiking, with trails threading around the Iveragh Peninsula (on the Kerry Way) or Dingle Peninsula (on the Dingle Way). Cycling is just as enjoyable as hiking, and you can take in much of the best of this west coastline on the Wild Atlantic Way, focusing on the snaking peninsulas, craggy islands, and colorful coastal villages of Co. Mayo. Or try some sea kayaking, with the Donegal region widely regarded as one of the best places for this activity in the world.  

Dublin & Eastern Ireland

Perhaps the best thing you could spend your time in this region in July doing is walking on the Wicklow Way which showcases the very finest aspects of Eastern Ireland and kicks off from Dublin's southerly suburbs (Marlin Park, where you could start the hike with the Longitude Festival which takes place in July). Or try a leisurely wander and swim on some of the region's stunning sandy beaches, lacing all of the eastern coasts.

Remember that this region is known as 'Ireland's Ancient East' and so, for a great insight into Ireland's prodigious history without spending too much time indoors, visit the Irish National Heritage Park near Wicklow. This walks you 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

Hiking in July is the activity that showcases Northern Ireland in all its wild beauty. The Causeway Coast is dramatic, but for all the publicity given to the Giant's Causeway, the hike that reveals this region's fantastic scenery better than any other is the 636-mile (1,024-km) Ulster Way, taking the walker to mountains, wild forests, and lakes as well as the breathtaking coastline. See above for the best sections of the Ulster Way to hike.

For a shorter walk, brave the vertiginous Carrick-a-Rede Rope Bridge connecting the wild island of Carrickarede to the mainland. Or spot locations from the TV series "Game of Thrones," with many filming locations scattered through this region.

Sights to check out in summer include the Downhill Strand in Co. Derry, and Tollymore Forest Park, in Co. Down. The seas are warm and quite calm and good for sea kayaking this month, and in this regard, Northern Ireland leads the way with its stunning North Coast Sea Kayak Trail between Co. Londonderry and Co. Antrim, passing the Giant's Causeway.
