Advantages of sailing in Croatia in September

Why you should go sailing in Croatia in September?

For a quieter, more relaxed holiday in Croatia, it’s best to avoid the peak season of July and August. In September, towns and islands have thinned out but retain a lively atmosphere. There’s ample space for mooring at lesser-known marinas, and there’s no need to reserve a berth in advance. The same goes for restaurants—you can find a table with ease, making it especially convenient if you’re traveling with a group.
Although there are fewer entertainment options than in high summer, September still offers some fantastic festivals and events. While many tourist venues close by late autumn, they remain open through September. The weather, too, is ideal: warm both on land and sea, but without the intense summer heat, making it comfortable for older travellers as well.

Weather in the Adriatic Sea in September

September marks a transitional period in the weather. Early in the month, sunshine lasts around 13 hours daily, with average temperatures between 23-26°C. By month’s end, sunshine decreases to about 10-11 hours per day, and cloudy or rainy periods become more frequent, with higher humidity bringing occasional brief showers. The sea remains warm at an inviting 23°C, ideal for swimming. September also sees a shift in winds; the northwestern mistral of summer gradually gives way to the northeasterly bora and southerly jugo winds.

A more peaceful atmosphere after peak season

In summer, the Croatian coasts of the Adriatic Sea are a little crowded. The high season comes to an end in September. It is easy to find a spot in the bigger marinas too. In September, all smaller Croatian towns living from tourism are open. Souvenir shops and attractions only close late October. You can discover everything in September without people everywhere.

Festivals and cultural events in September

Croatia hosts many events in September. You can visit several music and cultural festivals. A good example is Visualia in the town of Pula or the Dubrovnik Music Festival. The famous Split Film Festival is held in September, where you can watch several newly released movies of different genres.

One-way trip or round trip?

Towards the end of September, the wind can change several times a day, so regardless of the direction of travel, it is worth preparing for the challenges. If you go at the beginning of the month, you can sail southeast, thanks to the predictable mistral. In early September, with stable weather, shorter, one-way coastal routes are also suitable for beginners, but long, open sea sections require an advanced level. In the variable weather that prevails from the second half of the month, it does not matter from the point of view of wind whether you choose a one-way or a round trip. In this case, decide based on your itinerary. If you want to use the same port as your starting point and destination, then choose a round trip.

What costs do you have to count with?

The currency of Croatia is the Euro. You will have to pay around 60-100 euros for each port you visit. Food and drinks are relatively expensive compared to other Adriatic countries.
