Boka Kotorska, the Bay of Kotor in Montenegro, is a deep, winding bay surrounded by steep mountains. From the open sea at Herceg Novi it opens into a series of inner bays, through the narrow Verige strait, to Risan and Kotor. The mountains give the bay its beauty and its shelter, but they also make the wind behave differently from the open coast.
Mountain gusts. Because the mountains rise straight out of the water, winds from the land can fall down the slopes in sudden, strong gusts, especially in the inner bays of Kotor and Risan. A north-easterly Bura in particular can arrive with violent downdrafts while the sea stays fairly flat. Gusts can change direction as they follow the valleys.
Jugo. A south-easterly brings swell to the outer bay and the entrance near Herceg Novi, and often heavy rain. The mountains around the bay are among the rainiest places on the Adriatic coast, and in a Jugo visibility can drop fast.
Afternoon breezes. On settled summer days a sea breeze blows into the bay in the afternoon. Inside, it follows the shape of the bays, so its direction and strength vary from one part to the next.
Thunderstorms. Summer storms build over the mountains and can drop quickly onto the water with squalls and heavy rain.
Most small-boat days in the Boka stay inside the bay, where the sea is usually gentle. Watch the forecast for gusts rather than the average wind, look at the mountain tops for building cloud in the afternoon, and give yourself time to get back to your berth before a storm or a downslope wind arrives. Only head outside the entrance in settled weather with a small sea.
From Kotor or Tivat, the inner bay is the easy choice: the islets off Perast, the villages along the shore and the quiet bays around Risan. From Tivat and Herceg Novi, the Luštica peninsula and the coves near the bay entrance suit a settled morning. The open coast south towards Budva is a different proposition, exposed to the full sea, and should be kept for calm days with a good forecast for the trip back.
Navigate Boats covers the Montenegrin coast. Pick Kotor, Tivat or Herceg Novi as your base and the board gives a verdict for your boat, with the gusts shown beside the average wind. Always check the official forecast from the Montenegrin hydrometeorological service as well.

These guides describe typical patterns, not today’s weather. Navigate Boats is a planning aid, not a navigation tool: before you go, check the official marine forecast and warnings from DHMZ (Croatia), ARSO (Slovenia) or the Montenegrin hydrometeorological service, and use your own judgement.
