Visiting Dublin in January

January weather

January feels cold, damp and often grey in Dublin. Daytime highs are around 8°C, with lows near 4°C, and rain falls on many days. The short daylight and little sunshine can make afternoons feel gloomy, so keep outdoor plans flexible.

You can still enjoy a walk around Trinity College or along the River Liffey between showers. For a wet spell, head inside to the Chester Beatty or the National Museum of Ireland. Save long coastal walks around Howth for a clearer day; muddy paths and rain can make them less appealing.

Things to do

New Year's Day is a public holiday, so some sights and businesses may open late or stay closed. TradFest brings traditional Irish music to venues around Temple Bar in January, though dates change each year. Warm up afterwards with a bowl of seafood chowder in a city-centre pub.

Couples who like live music and cosy pub evenings may find January suits them better than a packed summer trip.

Crowds and practical tips

January is quieter than the busy months from May to July and September. You'll generally find fewer visitors at places like the Guinness Storehouse, and accommodation can cost less than in peak season. The trade-off is a smaller choice of outdoor activities and some grey, wet days.

For a rainy afternoon, use the covered walkways at the National Gallery of Ireland, then cross to Merrion Square when the weather clears. If you're taking the DART to Howth, check conditions before setting out; the exposed harbour walk is less fun in steady rain.
