Public holidays in Germany add to it. Cruise ships call on 4 of the 15 days. The crush is at the Landungsbrucken piers; the quiet is at the Alster shores. The calmest day is Wednesday 16 September, the busiest Sunday 20 September.

Can't move the dates? How to avoid the worst crowds
- Need flexibility? The 21st–25th is the month's calmest stretch — the easiest window to move around in.
- 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.
Travelling on a busy day?
Timed-entry and skip-the-line tickets turn queue time into sightseeing time — sort them before you fly.
