Kotor · Month comparison
September vs May
May ranks #1 overall vs September at #2. The optimal window: warm, genuinely beautiful, and before the cruise ship armada arrives in force.
September
#2 of 12 months
Best match
The second great window: sea still warm, crowds thinning, prices dropping, Old Town recoverable.
- ↑September is the second of Kotor's two recommended windows (alongside May) and many experienced visitors prefer it. The cruise ship season begins winding down from mid-September and by the last week the Old Town has noticeably more breathing room. The sea remains warm (24°C) and swimmable, and the surrounding mountains take on a golden-brown autumn quality that is genuinely beautiful.
- ↑Prices drop 25–35% from August levels as the high season ends. The same restaurants and hotels that were inaccessible without long-advance booking in July are available with short notice or walk-in. The konoba owners and hotel staff have time for their guests again.
May
#1 of 12 months
Best match
The optimal window: warm, genuinely beautiful, and before the cruise ship armada arrives in force.
- ↑May is the month that experienced Adriatic travellers point to as Kotor's best. Temperatures reach 22°C, the bay is a flawless blue-green, and the cruise ship season is beginning but not yet overwhelming — fewer than 50 ships typically call in May versus 300+ across the June–September season. The Old Town in May has its authentic Venetian-influenced character intact: the cats on the piazza steps, the fishing nets on the harbour wall, the konoba owners still glad to see you.
- ↑Kayaking across the bay to Our Lady of the Rocks (Gospa od Škrpjela) — the artificial island church off Perast built from coral and ex-votos over 200 years — is one of the finest half-day activities on the Adriatic. In May you can paddle to it without sharing the water with speed boats ferrying cruise passengers.

September trade-offs
- ↓September brings the return of significant rainfall: 102mm, often arriving as dramatic afternoon thunderstorms that roll quickly over the Orjen range. The weather can change from clear blue to a fierce storm in under an hour. Keep a flexible afternoon schedule.
- ↓The first two weekends of September still see meaningful cruise ship traffic and regional visitors from Serbia and Bosnia on holiday. The real relief in crowds comes from around September 12–15 when the summer holiday season ends across the region.
May trade-offs
- ↓Rainfall in May (110mm) is still meaningful and afternoon thunderstorms can develop quickly when warm air comes over the mountains. The bay weather can change fast — build flexibility into outdoor plans.
- ↓The early cruise ship season means that even in May, some mornings between 9am and noon will see the Old Town substantially busier. The narrow North Gate area and Trg od Oružja (the main piazza) get congested during ship-arrival windows.
