Kotor · Month comparison
December vs May
May ranks #1 overall vs December at #8. The optimal window: warm, genuinely beautiful, and before the cruise ship armada arrives in force.
December
#8 of 12 months
Worth considering
Wettest month of the year — the Old Town is practically empty and Christmas atmosphere is warm.
- ↑December is Kotor's wettest month (255mm) but also carries a genuine festive warmth — Christmas markets and lights in the Old Town piazzas, concerts in St. Tryphon Cathedral, and a local Christmas atmosphere that is entirely for residents rather than tourists. Prices are the lowest of the year.
- ↑Snow occasionally falls on the upper fortress walls and on the surrounding Lovćen mountain — rare enough to be remarkable and beautiful enough to justify the discomfort of getting there.
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.

December trade-offs
- ↓The 255mm December rainfall figure is among the highest single-month totals of any European coastal city. Prolonged rain is the dominant condition and outdoor exploration is severely limited. Many businesses operate minimal hours or close entirely between Christmas and New Year.
- ↓Cold nights (3–4°C), heavy rain, and minimal sunshine make December the hardest month for active sightseeing. The Old Town is atmospheric but physically challenging to enjoy.
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.
