September Sailing in Croatia: Why Regatta Season Is Worth Planning a Trip Around
By the last week of September, the summer crowds have begun to thin along the Croatian coast, but the sailing calendar has not gone quiet. On 26 September, crews arriving for Adriatic Sailing Week take over First 35s and First 36s in Biograd and Jezera before racing towards the Kornati area. Twenty identical or closely matched charter yachts are allocated across the two classes, with seven races planned during the week.
The timing is no accident. Croatia still recorded 2.4 million tourist arrivals and 11.9 million overnight stays in September 2025, more than in the same month a year earlier. Split-Dalmatia alone accounted for 2.4 million nights. Summer has loosened its grip, although the coast has hardly shut down.
For sailors, late September brings another change. The daily routine is less dominated by finding a berth before everyone else does. Restaurants and waterfront towns remain open, the sea has carried warmth from July and August, and boats are still moving between the central Dalmatian islands. Wind matters more again. That last point is part of the reason regattas gather here after the busiest holiday weeks.
When the charter fleet starts racing
Croatia’s charter industry is large enough for a regatta to borrow from an existing fleet rather than bring twenty racing yachts from elsewhere. Adriatic Sailing Week uses ten First 35s with gennakers from Marina Jezera and ten First 36s from Biograd. The First 35 is set up for crews of around five; the First 36 takes up to seven.
Once the boats leave the marina, the holiday configuration gives way to racing. Crews are not stripping interiors or rebuilding boats for competition. The rules keep the charter equipment aboard and restrict sail choice, which puts more weight on handling, tactics and crew work.
Seven races are scheduled in 2026, mixing windward-leeward courses with navigation races. If at least four races are completed, crews can discard their worst result. The overall fleet is scored under ORC, while the First 35 and First 36 groups also receive their own class rankings.
The 2026 event joins the Austrian Offshore Trophy as well, linking it with other Austrian offshore competitions such as the Round Palagruza Cannonball and the national offshore championship.
Someone chartering nearby may see the same stretch of water very differently during that week. One crew is choosing a lunch stop; another is looking at the next mark and working out whether a wind shift will pay.
September is still a serious tourism month
The quieter-coast cliché can be overdone because Croatia is not empty in September. Foreign visitors accounted for 11.2 million overnight stays in September 2025. German travellers alone booked 3.8 million, almost 34% of all foreign tourist nights during the month. Austria, Poland, Slovenia and the UK followed among the larger markets.
The numbers help explain why charter bases, restaurants and coastal services continue operating well beyond August. They also show why sailors should not arrive expecting deserted marinas simply because school holidays have ended.
Croatia had 216 nautical ports and related facilities included in the national statistical survey in 2025, among them 86 marinas and 71 anchorages. Together they provided 18’850 moorings. Sea berths averaged 78% occupancy over the year, while nautical ports generated almost €195 million in revenue.
Transit traffic is concentrated exactly where a central Dalmatian sailing trip tends to go. Split-Dalmatia handled 54’183 vessels in transit during 2025. Šibenik-Knin followed with 44’954, and sailboats represented 57.2% of all transit vessels using sea moorings nationally.
By late September, fewer holidaymakers are competing for the same infrastructure than in peak summer, but the marinas are still part of a working sailing economy rather than seasonal outposts waiting to close.
The Kornati change the week
The provisional routing for Adriatic Sailing Week points towards the Kornati archipelago. It is difficult to design a more natural race area for the event.
The islands break up the horizon into channels, open-water stretches and narrow passages. A navigational race there asks more from a crew than repeatedly sailing around two marks. Islands interrupt the wind, headings change and the coastline becomes part of the course.
For a charter crew watching rather than racing, the same geography encourages a slower itinerary. The Kornati are close enough to Biograd and Jezera to reach without spending an entire day on passage, while the surrounding Šibenik archipelago gives crews plenty of alternatives if the weather changes.
September also reduces some of the pressure to make every stop a famous one. A week does not need to become a sequence of Hvar, Brač, Vis and Split simply because those are the names everyone recognises. From Biograd or Jezera, Murter, Žut, the Kornati, Dugi Otok and the waters around Šibenik can fill a charter without sending the boat far south at all.
Regatta week adds movement to that landscape. Race boats leave in a group, crews gather again after finishing and the sailing community becomes much more visible around the marinas.
Come for the racing, or simply borrow its timing
You do not need to enter a regatta to plan around one. Arriving a few days before Adriatic Sailing Week gives you central Dalmatia while crews are collecting boats and preparing for the first start. Charter after the racing and many of the same islands remain within reach, only without the fleet moving through them together.
The event itself runs from 26 September to 3 October 2026, with racing beginning on Monday 28 September. That puts a Croatian sailing holiday squarely across the transition from September into October.
Weather forecasts deserve more attention at that point in the season than they might during a settled August week. The bora can arrive sharply from the northeast, while jugo brings a different pattern from the south and southeast. Neither belongs only to autumn, but late-season crews should leave enough room in an itinerary to stay put when conditions call for it.
A fixed seven-night plan with six compulsory overnight stops leaves little room for that judgement. Central Dalmatia does not require it anyway. The distances between Biograd, Murter, the Kornati and Šibenik are short enough to change plans without losing a day of the holiday.
Adriatic Sailing Week crews will be doing something more exacting with the same freedom. Their course is announced around weather, racing conditions and the race committee’s decisions. Charter sailors can afford to be even less rigid.
In 2026, twenty race boats will leave Jezera and Biograd carrying crews who have come to compete. Around them will be hundreds of other sailboats doing what Croatia’s charter fleet does every September: moving between islands after most of Europe has mentally declared summer over.
