The Maestral (Maestrale in Italian) is the friendly wind of an Adriatic summer. It is a north-westerly sea breeze that sets in on fine days, strengthens through the late morning and early afternoon, and fades towards evening. Sailors love it, and many charter weeks are planned around it. For small motor boats, RIBs and boats with children aboard, it is the wind that decides whether the afternoon crossing home is pleasant or a wet, bumpy ride.
The Maestral is driven by the difference in temperature between the land and the sea. On a sunny day the land heats up faster than the water, the air over the land rises, and air from the sea flows in to replace it. Along the Adriatic coast that flow, steered by the coast and the mountains, comes from the north-west. It is a fair-weather wind: a steady Maestral is usually a sign that settled weather is holding.
The strength varies with the day and the place. It is typically moderate, but it is noticeably stronger in channels that line up with it and off headlands, where the wind accelerates. When the sea breeze adds to a north-westerly from a weather system, the afternoon can be much windier than a normal Maestral day.
The Maestral is felt along the whole coast, from Istria to Montenegro, but it is most noticeable in the channels of central Dalmatia, between the islands off Split and Zadar, and anywhere the coastline funnels a north-westerly flow. Short, steep waves build quickly against a tidal or ferry wake, which matters more on a small boat than the wind speed itself.
The hour-by-hour view on the board shows the wind building and easing through the day for your base and destinations, and the verdict changes with it, so you can see whether the trip home after lunch is still a go for your boat. The “Best windows” card points out the calmer hours. Pair it with the official forecast, which also flags the days when a stronger north-westerly sits on top of the sea breeze.

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.
