Dublin
Beyond St Patrick’s week, the shoulders are cheap, walkable and just as green.
When to visit Dublin
Dublin is calmest in January and busiest in July. For the best balance of decent weather and smaller crowds, aim for February.
Dublin has a shallow crowd curve punctuated by one enormous spike. St Patrick’s Festival, around 17 March, runs for four or five days and brings hundreds of thousands of visitors into a compact centre; hotel rates that week are the highest of the year, higher than August, and they need booking months in advance. Take that week out and March is otherwise an ordinary, cheap, damp month.
The rest of the year follows the northern-European pattern with a modest ceiling. July and August are the busiest, helped by long daylight and a domestic and British holiday market, but Dublin never reaches the density of Edinburgh in August or Amsterdam in April — the visitor pressure lands on a short list of places, chiefly Trinity College, the Guinness Storehouse, Temple Bar and Kilmainham Gaol, rather than the whole city. December is the other lift, driven by Christmas shopping on Grafton and Henry Streets rather than by markets.
Weather should not drive the decision, because it barely varies: ten to thirteen rain days every single month, highs between 8°C in winter and 20°C in July. That makes the shoulder months genuinely attractive. May and September have the best light and the driest odds, February and November are the cheapest, and any month rewards having two indoor options ready. The one thing worth checking is the Six Nations calendar — a home rugby weekend at the Aviva fills the city as thoroughly as a bank holiday.

Local timing tips
- Book Kilmainham Gaol and the Book of Kells online well ahead — both are timed, both sell out, and neither takes reliable walk-ups in summer.
- The National Museum, the National Gallery and the Chester Beatty are all free and all excellent, which makes them the default plan when it rains.
- Drink in the Liberties or on Camden Street rather than Temple Bar, where a pint costs roughly half as much again for the same beer.
- Check the Six Nations and GAA fixtures before booking: a home international at the Aviva or Croke Park fills every hotel bed in the city.
