Is December a good time to visit Ireland?

If you're planning a trip to Ireland, December might not be the first month that comes to mind, but it definitely has its perks. Think festive lights, cozy bars, and dramatic winter scenery without the crowds.

The weather in Ireland in December is cold and damp, with temperatures hovering between 39°F and 48°F (4°C to 9°C). Rain is common, and daylight fades fast, so you’ll need to plan your days carefully. Snow is rare, except in the mountains, so you're unlikely to run into major travel disruptions.

Despite the chill, Ireland still delivers. Coastal drives like the Wild Atlantic Way are moodier but no less beautiful. Cities such as Dublin, Cork, and Galway come alive with Christmas markets, live music, and a festive buzz that’s hard to beat. Just pack your waterproofs, warm layers, and a sense of humor about the rain.

If you're looking to avoid crowds and want a different take on Ireland’s rugged charm, December can be a rewarding choice. It's not the best time to visit Ireland for sunshine or long hikes, but for vacation spirit, atmospheric landscapes, and quiet beauty, it’s hard to beat.

Why December is a good time to visit:

• Festive atmosphere: Towns and cities across Ireland light up for the vacations, with Christmas markets, live music, and cozy winter vibes everywhere you go.
• Fewer tourists: December is low season, so you’ll skip the tour bus crowds and enjoy popular spots like the Cliffs of Moher or Kilkenny Castle with more breathing room.
• Winter walks: Rugged trails like those in Connemara or along the Causeway Coast take on a moody beauty, just pack your waterproofs and embrace the elements.
• Bar culture at its best: There's nothing better than warming up by a fire with a pint in hand while local musicians play trad tunes in the corner.
• Better deals: Flights and accommodation are often cheaper than in summer, especially outside of Christmas week.

What about the crowd and cost?

December in Ireland is part of the off-peak tourist season, which means fewer crowds at popular attractions. If you prefer a more relaxed travel experience, this is the perfect time to visit. Cities closer to Christmas see a slight uptick in visitors thanks to festive events and markets, but it's a far cry from the summer chaos of high season.

Due to lower demand, accommodation and airfares are usually more affordable in December. You'll also find deals on tours and activities, making this period a budget-friendly option for exploring Ireland's winter charms.

Where to go in Ireland in December

If you’re looking for the best places to visit in Ireland in December, think festive cities, quiet countryside escapes, and windswept coastal views. The weather’s cold and often wet, but that doesn’t stop the country from putting on a good show, especially around the vacations.

Dublin

Ireland’s capital pulls out all the stops in December. Grafton Street glows with lights, bars are packed with live music, and Christmas markets pop up across the city. You can duck into the Little Museum of Dublin or the National Gallery when the weather turns, then warm up with a hot whiskey in a candlelit bar.

For New Year’s Eve, head to the Liffey Lights Midnight Moment, an outdoor celebration with music and light shows.

Galway

Galway feels like a proper winter postcard this time of year. The Galway Continental Christmas Market runs through most of December, filling Eyre Square with wooden chalets, mulled wine, and carousels.

The city's compact center makes it easy to explore between rain showers, and there’s always a trad session happening in a nearby bar. It’s less crowded than in summer, but still lively.

Killarney and the Ring of Kerry

Killarney stays open year-round and makes a great base for exploring the Ring of Kerry without the tour bus traffic. The scenery is wilder and moodier in winter, think misty mountains and empty beaches.

Wrap up well and you’ll have places like Ladies View or Muckross Abbey almost to yourself. Many cafés and guesthouses stay open, especially around the vacations.

Dingle Peninsula

Dingle is quieter in December, but that’s part of the charm. Local bars still serve up live music, the town’s seafood is as fresh as ever, and the Slea Head Drive is hauntingly beautiful under winter skies. Some attractions may close for the season, so check ahead, but if you’re after windswept walks and no crowds, it’s a solid bet.
