Kotor (Montenegro) — sää kuukausittain

Forum posters describe January as genuinely wet and grey - real rain is common, and the town's cobblestone streets get slippery and less enjoyable to walk in the rain, a specific practical annoyance posters mention often. January counts as deep off-season not just for Kotor but across the whole Balkan region, with many businesses closed for the winter except around Orthodox Christmas/New Year, when things pick up for about a week. Despite the grey, damp conditions, posters describe shops in the old town staying open and functional, and at least one visitor specifically praised a winter boat tour of the Bay of Kotor as the highlight of an otherwise quiet, rainy trip - suggesting the dramatic fjord-like scenery still delivers even in the off-season.

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.

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.

Kotor's forum calls July hot, consistently over 30°C by day with nights rarely dropping below 20°C, and rainy or cloudy days genuinely rare. Regulars recommend scheduling anything strenuous like the fortress climb for the morning to beat the peak afternoon heat, and flag July as both hot and crowded compared to the shoulder months.

August in the Bay of Kotor is hot and busy, and the forum is precise about both. Daily temperatures practically never drop below 30C and pass 35C easily; several regulars say they would return in September instead. On crowds the walled town fills fast, but the bay imposes its own limit - only two cruise ships at a time, one docked and one moored out with tenders - and they are usually gone by about 5pm, so the evening belongs to the town again. The crush extends along the coast from Perast through Tivat and Budva, though even in August posters report having small beaches to themselves early and late. The record: 32.8C days that feel like 37C, 19C nights, 10.2 precipitation days, 12.3 hours of sun and a 26.9C sea.

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.

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.
