The summer months of June to August are the best time for good weather

While the summer will see the city packed with tourists, Dublin comes alive in good weather as everyone makes the most of their chance to soak up the sun. Crowds will throng to beer gardens, parks, and the city’s north and south canals. It’s a great time to wander the streets, admiring the architecture or following in the footsteps of James Joyce’s famous protagonist of Ulysses, Leopold Bloom. Brave travelers can head to the Forty Foot or one of the city’s many beaches for a bracing sea swim, or take a long stroll or bike ride through Phoenix Park. This is also a good time to head south for a hike in the Dublin Mountains or take one of the city’s coastal walks, followed by pints at a pub with a view.

Mix culture and the outdoors in March to May, September and October

Hints of spring will enter the air in March and Dublin will see the country’s most famous celebration on St Patrick’s Day. The city will flood with visitors ready to party, as many Dubliners retreat from the center to avoid the chaos. As spring continues, travelers should seize a nice day by exploring Dublin’s beautiful green spaces, like St Stephen’s Green or the Iveagh Gardens, with rainy days spent in the city’s many museums, such as the Little Museum of Dublin or the National Gallery. 

In the autumn, head out of the city for a day trip to Glendalough, where you can admire the fall colors. September and October are great for those who want to sample Dublin’s incredible cultural offerings, as September brings the Dublin Fringe Festival and October the Dublin Theatre Festival.

Get cozy in pubs during the winter months of November to February

The weather in Dublin is likely to be cold, wet and dreary throughout the winter season. If you aren’t used to the damp and cold, prepare to be chilled through. But this can be a great excuse to do as the locals do and pack into cozy pubs, see comedy shows or listen to live music. December will see the city light up with Christmas spirit, and the high streets will buzz with window displays and pretty lights. You may want to book tables for dinner, as pubs, restaurants, and bars will fill up with friends, families, and coworkers gathering in large groups to celebrate the holidays. Once the festive season is over, locals lay low, and January and February will be much quieter. This is a great time to explore museums or make like a Dubliner and visit one of the city’s independent cinemas, such as the Light House Cinema or the Irish Film Institute.
