Average daily temperatures in January

In January, average daily temperatures in Ireland range from highs of 46°F (8°C) to lows of 37°F (3°C). While it’s cold, Ireland’s winter is milder than in many European countries, though damp conditions make it feel chillier.

Regional variations are subtle but worth noting:

• Eastern areas like Dublin tend to be drier but slightly colder, with temperatures sometimes dipping below freezing overnight.

What about the crowd and cost?

January is firmly in Ireland’s off-peak season, meaning far fewer tourists at top sights like the Cliffs of Moher or Kilkenny Castle. Post-holiday calm makes it ideal for travelers seeking quiet coastal drives or tranquil hikes without the summer crowds.

With lower demand, accommodations and flights are often cheaper, and you’ll find plenty of winter deals on tours and attractions. However, some rural businesses may close for the season, so check ahead when planning your itinerary. If you value solitude and a budget-friendly trip, January is a great time to experience Ireland’s unspoiled charm.
