Insider timing tips
- •While summer (June-August) offers the best weather, it also brings peak crowds and prices. Shoulder months like May and September provide a good compromise.
- •The 'Irish summer' is relative; expect mild temperatures and the possibility of rain even in July and August. Layers are essential year-round.
- •St. Patrick's Day (March) and the weeks surrounding Christmas and New Year's are exceptionally busy and expensive, often surpassing general summer peaks for specific dates.
- •Many smaller, independent shops and some restaurants may close for a few days around Christmas and New Year's, even if major tourist attractions remain open.
- •The long daylight hours in June and July make late-night sightseeing and enjoying outdoor pubs very pleasant, extending the usable hours of your day.
