Book a Riviera berth for September and you are bidding against a calendar, not just against other owners. Between 6 September and 4 October 2026, seven championships and shows run almost end to end across the harbours from Porto Cervo to Saint-Tropez — and two of them fill the docks with the boats on display. The dates below are the difference between the month you planned and the month that was left over.
Two shows take whole harbours out of service
The Cannes Yachting Festival runs 8–13 September 2026 and occupies both of the town's harbours at once — the Vieux Port and Port Canto. It is an in-water show, which means those basins are the exhibition rather than somewhere to tie up. Friday the 11th is the late night, open until 22:00; the other days close at 19:00, and Sunday at 18:00.
Ten days later the Monaco Yacht Show does the same to Port Hercule, 23–26 September, Wednesday to Friday 10:00–18:30 and Saturday to 18:00. Port Hercule carries 760 berths and monitors VHF 12 around the clock, and show week is the hardest week of the year to walk into cold. If Monaco is the point of the trip, the berth conversation happens months ahead of the show, not the week of it.
Porto Cervo owns the first half of the month
Sardinia's north-east corner runs two championships back to back. The Yacht Club Costa Smeralda hosts the Maxi Yacht Rolex Cup from 6 to 12 September and the Rolex Swan Cup from 13 to 19 September, so Sardinia is a race village for two solid weeks before the Riviera calendar even warms up. The same club then runs its J/70 Cup and Italian Championship from 29 September to 4 October.
What that means in practice: if you want Porto Cervo in September, you are sharing it with a maxi fleet and its shore teams. Go anyway — the racing is the reason to be there — but plan the arrival, and plan an alternative anchorage in the Maddalena archipelago for the nights you cannot get alongside.
Cannes and Saint-Tropez hand the season off
The Yacht Club de Cannes runs the 48th Régates Royales from 19 to 26 September, with classes from big boats through the classic Marconi and Époque fleets. It overlaps Monaco's show by four days, which is the tightest knot in the whole month: classic yachts racing off Cannes while the superyacht fleet lies alongside in Port Hercule.
The handoff comes immediately. Les Voiles de Saint-Tropez runs 26 September to 4 October, organised by the Société Nautique de Saint-Tropez, a club that has been sailing since 1862. The gulf off Saint-Tropez takes the classics, the maxis and the modern fleet together, and the town works to the racing schedule for nine days.
The two gaps
There are exactly two windows inside this stretch where the western Riviera is quiet, and they are worth building a trip around.
The first is 14–18 September. Cannes has struck the show, the Régates Royales has not started, and the coast between Antibes and Saint-Tropez is briefly just a coastline again, with warm water and no fleet.
The second opens on 5 October, once Saint-Tropez packs up. The weather is still holding, the anchorages have emptied, and the harbour offices have time to talk to you again. That is the same argument our Mediterranean shoulder-season piece makes, and September's calendar is the sharpest illustration of it.
October is still a season
Two more dates keep the autumn alive well past the Riviera's exit.
Barcolana takes over the Gulf of Trieste from 2 to 11 October, run by the Società Velica di Barcola e Grignano. The main race starts at 10:30 on Sunday 11 October over a fixed-vertex quadrilateral of 13 nautical miles, with the line set between Barcola and Miramare and the finish in front of Piazza Unità. It is a spectacle from the water and a genuine reason to be in the Adriatic in October.
Then the Barcelona Boat Show returns to Port Vell from 14 to 18 October, organised by Fira de Barcelona across the harbour's quays and marina.
The boat that makes a month like this work
A September like this rewards a boat that is easy to place. You want something that goes stern-to into a crowded basin without drama, carries guests comfortably on a half-day hop between one event harbour and the next, and gives you a swim platform worth using when the plan changes and you spend the afternoon at anchor instead.
Two very different answers to that. The Riva 76' Perseo Super is the one that looks right on this coast and is small enough to find a berth when the big fleet has taken everything. The Azimut Grande 26M is the one you actually live aboard for the full month, following the circuit from Porto Cervo to Port Vell without checking into a hotel once.
Tony's Take
Everybody books Monaco. The week I want is 14–18 September — the Cannes show has packed up, the Régates haven't started, and for five days you get the Riviera at full temperature with none of the crowd. Anchor off the Îles de Lérins, run into Antibes for dinner, and watch the Régates fleet arrive at the end of it. If you only take one week off this autumn, take that one and let everyone else fight over the last weekend in September.
