Sailing Around 15 August: Public Holiday, Packed Harbours, How to Cope
15 August marks the peak of the Mediterranean high season: harbours full, anchorages packed by 11am. How to book and plan around it anyway.
By Clément Lacaille, editor of Boat-Comparator · updated
15 August, the Feast of the Assumption, is a public holiday across France, Italy, Spain and Greece — a day off for a large share of the continent, which, unsurprisingly, heads to the water at the same time. It's statistically one of the busiest single days of the entire season on Mediterranean coasts.
A peak concentrated into a few weeks
A study of tourism seasonality across Mediterranean islands confirms what every operator sees firsthand: activity concentrates heavily in July and August, with sizeable swings in visitor numbers between the height of summer and the rest of the year depending on the archipelago studied (Ruggieri & Platania, Sustainability, 2024, see the study). 15 August sits right at the centre of that peak.
What actually changes on the day
Popular anchorages fill up by 10–11am, well earlier than the usual high-season pace. Free berths become scarce, even for a single overnight stop. Operators book out weeks ahead for the most requested slots, especially the weekend bracketing the date.
How to plan around it
- Book early: our guide to how far ahead to book recommends several weeks' lead time for mid-August, against just days in low season.
- Leave early in the morning, before 9am if possible, to reach an anchorage while it's still open and enjoy calmer water.
- Aim for a shifted date: the 14th or the 16th is often noticeably quieter than the public holiday itself.
- Have a backup anchorage in mind, a second cove nearby in case the first is full on arrival.
A budget that follows demand
Rental rates and marina fees both climb accordingly over this period: our guide to renting in August covers ways to keep the bill down, and our guide to the best anchorages on the French Riviera helps spot alternatives to the busiest spots.
