Can't move the dates? How to avoid the worst crowds
- Need flexibility? The 12th–19th 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.
September weather in Berlin
Comfortably warm — around 21°C / 69°F, easy shirtsleeve weather, with rain on about 7 days, so keep a layer handy.
Worth booking the marquee sights ahead for the busy days, but you can keep the rest of the trip flexible.
