Kotor in May — Full Picture
May is arguably the best month to visit Kotor — warm, sunny, and lively without the July-August crush. It averages 23°C/14°C with long days and easing rain.
The town is in full swing: all-day sightseeing in summer clothes, boat trips to Perast running near-full schedules, and Lovćen and Budva day trips easy. By late May the bay warms toward swimmable (~19-20°C), so beach time becomes an option alongside the Old Town and the walls climb. Cruise traffic is building but hasn't peaked.
Crowds and prices are higher than April but still well below the summer peak — you'll want to book popular konobas and boat tours ahead, but the Old Town doesn't feel overrun. The walls climb is glorious in the milder air.
Pack light summer clothing, a hat, sunglasses, sunscreen, and a packable rain layer (the bay still sees showers). For the best balance of weather, swimmable sea, and manageable crowds, May is hard to beat.
