- Need flexibility? The 16th–18th 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.

Is September worth it in Bari?
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 October or November.
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.
