Hvar and Vis sit south of Split, beyond Brač and Šolta. Hvar is a long island with a busy town, the Pakleni islands just west of it, and a channel on its north side that looks sheltered on a chart. Vis is further south, with no bridge and a crossing that leaves the channels behind. For a small boat the two are different decisions: a day among Hvar’s bays is a channel trip, and a day to Vis is an open-water trip. This guide is about that difference, and about the winds that decide it. The Split guide covers the start of the same water.
North of Hvar is the Hvar Channel, with Brač on the far side. South of Hvar the coast faces more open sea, and the gap onwards to Vis is wider still. The Pakleni islands are a compact group off Hvar town, close enough for a short hop and full of small bays. Vis and its neighbour Biševo lie out on their own. Ferries and catamarans run the same lines a small boat wants, especially into Hvar town and on to Vis, so the traffic is part of the plan, not a surprise.
Nothing here is a measured distance you should treat as a passage plan. What matters is the character: the channel gives you land on both sides, and the Vis crossing does not.
Maestral. On a settled summer day the north-westerly sea breeze fills the Hvar Channel from late morning and is often the strongest wind of the afternoon. It meets ferry wakes and raises a short chop. The Pakleni bays on the south-west side of that group are a common place to sit out the worst of it. Read the Maestral guide for the daily rhythm, and do the longest hop in the morning.
Jugo. A south-easterly sends swell onto the south coast of Hvar and onto Vis, and it runs along the channel as well. Bays that face south or south-east become uncomfortable, and the open water south of Hvar is the wrong place for a small open boat while it is building. The Jugo guide explains why the sea lasts after the wind eases.
Bura. The Bura is less the story here than it is under Biokovo or Velebit, but a strong north-easterly still crosses the channel and can be gusty where it comes off the land. The north side of Hvar faces that wind. The south side is calmer in a Bura and more exposed in a Jugo, which is the usual island trade.
Thunderstorms. Summer storms that build over the mainland can cross the channels in the afternoon. A clear morning is not a promise about four o’clock.
From Hvar, a good small-boat day is an early move to a Pakleni bay or along the channel, lunch out of the afternoon breeze, and a return before the Maestral peaks. From the mainland or from Brač, cross the channel in the morning. Save Vis for a day when the forecast keeps the wind moderate and the sea small for the whole round trip, not only for the departure. If DHMZ has a wind warning, or the board for your boat says stay in, believe that over the wish to see the island.
Set Hvar, Vis or a mainland base such as Split and open the live board. It names the wind, shows gusts beside the average and reads the wave height into the verdict for your own boat. It will not call the day better than a DHMZ wind warning allows. Use it with the official marine forecast from DHMZ.

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.
