Traveller notes on Kotor in December
Notes from nearby Podgorica (41 km away)
Kotor doesn't have its own notes for December yet — these are about Podgorica, close enough to share the season.
Forum posters describe December daytime temperatures around Podgorica and the coast as often 17-20C and sunny, genuinely pleasant for walking through old towns, though posters are direct that snow essentially doesn't happen in Podgorica or along the coast - it's confined to the mountainous areas above the coast and further north. Posters describe December weather here as still warmer overall than central Europe, even accounting for real rain and strong coastal winds that can make biking or boat trips impractical. Posters flag December as a genuinely quiet month countrywide, describing it as a period of deep hibernation with little in the way of festivals, since local Orthodox Christmas isn't celebrated until January 7th. Posters generally rate December as a mild, low-key time to visit Podgorica, with mountain areas the better bet for anyone specifically wanting snow.
Other months in Kotor
Regulars are specific this counts as a genuinely good month to visit for longer daylight, more sunshine hours and lower prices before the summer crowds arrive, though the Bay of Kotor itself is honestly one of the rainier corners of the whole Mediterranean, spring here running wetter than the coast further south. Our row backs that mild, genuinely wet read, 24.4C reading as a hot 26C, over 11.2C nights feeling 11C, with a substantial 198.4mm of rain across 17.8 days and humidity at 77 percent. Regulars are consistent the sea itself rarely crosses 20C by this point, fine for sunbathing but not yet warm enough for a comfortable swim for most visitors. Sunny stretches still prevail across most of a typical day despite the real rain risk. The sea sits at 19.1C. The record: 11.2 hours of sun, a 10.3 kph wind and AQI 44.
Kotor-forum threads on October weather call it genuinely pleasant and one of the more popular shoulder-season picks - warm days, cooler nights, and rain that shows up on a real number of days but doesn't fall every day. Posters are specific that any given shower tends to be heavier but short-lived rather than a settled, all-day soak, easy enough to plan around. The month splits cleanly in two: the first half still lively, essentially every restaurant and bar open and operating normally, while mid-October marks the real turning point as the town starts winding down for winter, though most places stay open through month's end regardless. The combination of good weather and thinning crowds is exactly why regulars call October one of the best times to visit both Kotor and nearby Dubrovnik together. The record: 23.9C days feeling like 24C, 10.9C nights, a notably high 211mm across 10 days, a 23.2C sea, 78 percent humidity and 8.2 hours of sun.
Montenegro-forum threads on September weather (the numbers track Kotor specifically) describe a month that eases gently: air in the high 20s to low 30s Celsius in the first half, a few degrees cooler in the second, with the Adriatic holding around 24-25C the whole time - genuinely perfect swimming weather by any measure. Precipitation isn't absent, just concentrated: posters describe maybe one sudden, heavy downpour across a week-long stay, over quickly and followed by more of the day's abundant sunshine. Nights cool off enough that a jacket earns its place and no air conditioning is needed to sleep, a detail more than one poster calls out as the month's quiet selling point. The record: 28.2C days feeling like 31C, 15.3C nights, 193mm of precipitation across 11.2 days, a 24.5C sea and 10.1 hours of sun - warm days, genuinely cool nights, occasional real downpours mixed through mostly clear skies.
June is the month regulars point to for Kotor - mid-June especially, which they call much better than July or August - and almost all of their advice is about ships rather than weather. Two or three cruise ships call on most days in season, three can be alongside at once carrying more than five thousand people between them, and the old town is small enough that an arrival gets described as a human flood. The workable plan is the clock: the streets are quiet before nine, the middle of the day is the part to spend elsewhere, and late afternoon and evening give the town back. Checking which days have no ship is the other move. Our row's 92.8mm across 13.6 days is the wet surprise inside a 29.8C month. The record: 16.2C nights, 12.9 hours of sun and a 24.1C sea.
