What is the weather like in Ireland in January?

*Long-term monthly averages.*

January in Dublin is cool and mild at once. Afternoons reach 46°F (8°C) and nights drop to 36°F (2°C), so a coat and a scarf do the job and heavy winter gear isn’t needed. Cork runs a touch milder at night, with a high of 47°F (8°C) and a low of 38°F (3°C).

Rain falls on 12 or 13 days of the month in Dublin, and the sun averages 1.9 hours a day in January. Cork gets 5 inches (131 mm) of precipitation in January, roughly twice Dublin’s 2 inches (62 mm). Wear a waterproof jacket and keep outdoor sights for the drier hours of the day. The museums, the Old Library and the pubs fill the rest.

February in Dublin has 11 rainy days and about three hours of sun a day. The temperatures barely move across the three months, so the difference you’d feel is the light and the rain.

Where to go in Ireland in January

Dublin

Trinity College, founded in 1592, holds the Book of Kells in its Old Library. The Guinness Storehouse sits at St. James’s Gate Brewery, and Kilmainham Gaol and Dublin Castle are among the sights in the city.

Temple Bar

Temple Bar has boutiques, cafés, galleries and pubs, and it has the highest density of pubs in Dublin. It also has three theatres: Smock Alley, the Projects Arts Centre and the Olympia. A January evening here can be spent indoors from the first stop to the last.

Galway

Galway’s Latin Quarter is less than five minutes’ walk from Galway Market, and its cobbled, pedestrian streets have unique shops, cosy pubs and street performers. Galway City Museum sits behind the Spanish Arch, close to the River Corrib. Dress for the rain, since much of the walking here is outdoors.

Cork

Cork has the English Market, the Shandon Bells at St Anne’s and Blarney Castle with its stone and gardens. It’s also the wetter of the two cities in January, with 5 inches (131 mm) of precipitation. Group the market and the tower into one day and keep the castle gardens for a break in the weather.

What to do in Ireland in January

The Book of Kells and the Red Pavilion at Trinity

The Book of Kells Experience includes entry to the Old Library and to the digital exhibition in the Red Pavilion. The pavilion houses three immersive digital exhibitions, all indoors.

Trinity Trails adds a 45 minute guided walk around the campus grounds, in English. In January, put it on a drier part of the day and wear a warm layer, since the walk is outdoors.

The Guinness Storehouse and the Gravity Bar

The Guinness Storehouse is at St. James’s Gate Brewery. The experience includes the Gravity Bar, with 360° views of the city.

Views like that depend on the sky, and January sun averages 1.9 hours a day. Go on a day when the clouds look thin and the view will pay off.

Kilmainham Gaol by guided tour

Kilmainham Gaol is one of Dublin’s most popular visitor attractions. Access is by guided tour only, so arrive in good time for your tour slot rather than turning up and wandering in.

It’s another roof for a rainy day, and a good fit for the 12 or 13 days of rain that January brings to Dublin.

Galway Market and the Latin Quarter on a weekend

Galway Market runs every Saturday and Sunday and has grown to include hundreds of stalls. It’s less than five minutes’ walk from the Latin Quarter, so the two make one outing.

Plan the stalls for the weekend and keep a rain jacket on. Afterward, warm up in the Latin Quarter’s pubs or in Galway City Museum, which has three floors of galleries.

The Shandon Bells and the English Market in Cork

At St Anne’s, visitors can play the Shandon Bells, see the inner workings of the four faced liar clock and climb the tower. It’s a hands-on stop for a short January day.

The English Market offers quality meats and fish, herbs, spices, fruit, vegetables, baked delicacies and speciality cheeses. Cork gets more rain than Dublin in January, and the market is a sensible place to spend it.

Is Ireland busy in January?

Accommodation across Ireland is listed in national registers of approved and registered providers. They cover hotels, guesthouses, bed and breakfasts, historic houses, hostels, camping, self-catering and holiday cottages, so there’s a wide range to choose from.

Rooms also exist outside the usual hotel stock. Maynooth Campus in County Kildare offers accommodation on a university campus, with rooms from student style to superior suites. Check the registers and book the rooms for the cities you plan to use.

Can you swim in Ireland in January?

The sea near Dublin averages 48°F (9°C) in January. That’s a monthly average, and it’s cold for getting in. December sits at 51°F and February at 47°F, so the water won’t warm up before spring.

Salthill Beach in Galway is made up of several small beaches separated by rocky outcrops. It’s popular for walking, swimming and relaxing, and it’s lifeguarded during the summer months. In January the Promenade is the better use of it, with open views of Galway Bay, the Burren Mountains and the Aran Islands.

What to pack for Ireland in January

January asks for layers and rain gear, since days are cool, nights are close to freezing and showers are frequent.

• A waterproof jacket, for the 12 or 13 rainy days of the month
• Warm layers, for a night low of 36°F (2°C) and an afternoon high of 46°F (8°C)
• Shoes with grip, for the cobbled streets of Galway’s Latin Quarter
• A hat and scarf, for the Trinity Trails walk and the Salthill Promenade
• A compact umbrella, for hopping between museums and pubs

What to know before visiting Ireland in January

Several Dublin sights have set addresses worth saving before you go: St Patrick’s Cathedral at St Patrick’s Close (D08 H6X3), EPIC in the chq Building on Custom House Quay (D01 R9Y0) and the National Museum of Ireland at Kildare Street (D02 FH48) and Collins Barracks on Benburb Street (D07 XKV4). Kilmainham Gaol is by guided tour only.

Galway Tourist Information Centre is at Galway City Museum, Spanish Parade (H91 CX5P).

Is January a good time to visit Ireland?

Yes, January is a good month for travelers who want museums, theatres, pubs and markets, and who don’t mind rain and short sunny spells. Daytime highs of 46°F (8°C) make walking between sights comfortable in a coat.

If you want swimming, January isn’t the month: the sea near Dublin is 48°F (9°C). If you’d like family activities indoors, EPIC has 20 interactive galleries and the Red Pavilion has three immersive digital exhibitions. For a market day, plan around the weekend in Galway.
