Four distinct seasons run through the year here, from January's chill to July's warmth, with rain spread fairly evenly across the calendar rather than concentrated in one stretch. In June, expect highs around 18°C with rain on roughly 9 days of the month.
St. Patrick's Day (March) — A national holiday with parades across the country, centered on Dublin, on March 17.
The Wild Atlantic Way's coastal drives and cliffside views define the west, while Dublin's pubs and literary history anchor the east.
Try a traditional Irish stew or fish and chips, alongside a pint of Guinness or a glass of Irish whiskey — both are genuinely central to Irish pub culture, not just tourist novelties.
