The Kornati are one of the densest island groups in the Mediterranean, a maze of bare limestone islands, islets and reefs between Šibenik and Zadar. Much of the archipelago is a national park. Day trips usually start from Murter, Pakoštane, Biograd na Moru, Sali on Dugi otok or the marinas around Šibenik and Zadar. The scenery is the draw. The weather and the distances are what you plan for.
Maestral. On settled summer days the north-westerly sea breeze fills in from late morning and blows through the channels in the afternoon. The long channels between the island rows line up with it, so afternoons can be lively. Cross the open stretches early and keep the return leg in mind.
Bura. The Kornati lie further from the high mountains than the northern coast, so the Bura usually arrives less violently than under Velebit, but it still brings strong gusts and a short sea across the channels between the mainland and the islands. Coves facing north-east are uncomfortable, and crossing from the mainland side can be wet and rough.
Jugo. The outer, seaward side of the Kornati faces the open Adriatic, with high cliffs and no shelter. In a Jugo the swell runs along that coast and into bays open to the south-east. Keep to the inner channels, or stay in port when a strong Jugo is forecast.
Thunderstorms. Summer storms can build quickly over the mainland and move out over the islands, with sudden squalls from an unexpected direction. Watch the sky inland in the afternoon.
Leave early, cross the open water in the calm morning, explore the inner channels at midday, and start back before the afternoon Maestral is at its strongest. If the forecast shows Bura gusts or a building Jugo, choose a shorter trip in the lee of the nearer islands, such as along Murter, Pašman or the Telašćica side of Dugi otok, instead.
Set Murter, Pakoštane, Biograd or Sali as your base and the board gives you a go, caution or stay-in verdict for your own boat, with the wind, gusts and wave height hour by hour for the islands around you. The trip list ranks destinations by how well they fit today’s weather and your daylight. For bases near the park the app also adds notes on the park itself. Always check the official DHMZ marine forecast and warnings too.
Check today’s go/no-go for your boat
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.
