Can't move the dates? How to avoid the worst crowds
- The heaviest port day is Sun 16 May — 6 ships in at once. See the marquee sights on a lighter day, or be there for opening time.
- On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.

Timed-entry and skip-the-line tickets turn queue time into sightseeing time — sort them before you fly.

Comfortably warm — around 21°C / 71°F, easy shirtsleeve weather, with rain on about 7 days, so keep a layer handy. The days are long too — close to 14 hours of light — so the evenings stay open for walking once the heat drops.

Is May worth it in Barcelona?
Peak weather and peak crowds — the classic trade-off; you pay for the season in queues, not in the weather. For better value, come in November or April.
Book beds and the big-ticket sights well ahead, and start your days by eight — in a month this full, the early hours are the only uncrowded ones.
