Offshore sea, from the Copernicus Marine model (about 4 km grid): near the coast and in sheltered harbours, the sea is often calmer.

The Mediterranean marine weather changes from one headland to the next: the mistral can blow hard in Marseille while the sea is glassy in Bonifacio, and an easterly gale can close the anchorages of the Côte d’Azur while sparing the Balearics. This page gives you, for each port, the wind measured live, the 24-hour forecast, a large Windy map and maritime traffic.
The page address follows the place you choose: you can save it or send it to your crew to go straight to the weather at your destination. Further down, our skipper’s tips on Mediterranean winds, Météo-France bulletins and preparing a crossing to Corsica or the Balearics.

Each link opens this page centred on the port: the map zooms in, the wind is animated and the Windy and AIS maps re-centre. For a place not on the list, use the search, which works for the whole coast and the islands. To find the distance between two of these ports, use our port-to-port distance calculator.
The Mediterranean has its winds, each with its name, its season and its way of raising the sea. Recognising them on Windy lets you anticipate far better than a simple figure.
It comes down the Rhône valley, blows over Provence and extends as far as Corsica and Sardinia. Cold, dry and often violent, it lasts several days. Near the Provençal coast, it comes from land: the sea stays flat close to the shore but builds quickly offshore, where the waves are short and powerful. It is the wind that calls for the most vigilance on a crossing to Corsica.
A cousin of the mistral, it blows between the Pyrenees and the Massif Central, over Roussillon and the Gulf of Lion. It can raise a rough sea as far as the Balearics.
Humid and often accompanied by rain, it comes from offshore and pushes a swell into bays facing east and south: Cassis, the south harbour of Marseille, much of the Côte d’Azur. Even when moderate, it makes anchorages rolly.
Feared in Corsica, particularly on the west coast and Cap Corse, it raises a rough sea and can make the entrance to some ports tricky.
Hot, sometimes laden with Saharan sand, the sirocco crosses the Mediterranean and brings a southerly sea. On the Provençal coast, the humid south-easterly is often called the marin.
In fine summer weather, the sea breeze rises in late morning and drops at sunset. Regular and predictable, it is the wind of beautiful sailing days.
Maps and models do not replace official bulletins. For the French Mediterranean, the reference is Météo-France.
It covers the coastal strip up to 20 miles, by sections of coastline, with wind, sea, swell and visibility for the next 24 to 48 hours. It is the bulletin to read before any day trip.
It divides the sea into large named areas, such as Lion, Provence, Ligure, Corse or Baléares. It is the one to check before a crossing or a delivery.
A BMS is issued as soon as the wind reaches or is likely to reach force 7 in an area. It is broadcast by CROSS on VHF, announced on channel 16. A BMS in force is the signal to stay in port or return.
At sea, the VHF remains the safest way to receive warnings. Monitor channel 16 at all times, as required by Division 240 for any equipped boat.
| Crossing | Distance | Indicative duration | Wind to watch |
|---|---|---|---|
| Marseille → Ajaccio | 186.4 miles | about 35 h 30 min at 6 knots, margin included | Mistral and easterly offshore |
| Marseille → Calvi | 167.8 miles | about 32 h | Mistral, cross sea near Corsica |
| Marseille → Porquerolles | 52.3 miles | about 10 h | Easterly on arrival |
| Marseille → Mahón | 220.7 miles | about 42 h 30 min | Rough sea in the Gulf of Lion |
| Marseille → Palma | 291.4 miles | about 56 h | Tramontane and mistral in the Gulf of Lion |
A crossing is prepared over several days of forecasts. The distances above are orders of magnitude: calculate your exact route with the distance calculator.
You need a stable window covering the whole duration of the crossing, plus a margin. Beware of the end of mistral episodes, when the wind seems to drop in Marseille while the sea remains very rough offshore, and of depressions that deepen a fast easterly.
Scroll Windy over the whole planned duration, compare wind and gusts, then show the swell: a residual sea of 2 metres, even without wind, makes a crossing long and tiring.
To take your boat to Corsica or the Balearics, our professional skippers carry out the delivery to Corsica and the delivery to the Balearics, choosing the right weather window.
Reading the marine weather in the Mediterranean is above all about knowing which coast will be protected. Here are the benchmarks our skippers use on the busiest waters.
In a mistral, the coast is sheltered from the sea since the wind comes from land: the Côte Bleue, the north harbour of Marseille and the heads of the bays remain navigable, provided you stay close to the shore. In an easterly, by contrast, you look for coasts facing west, such as the north of the Frioul islands or the bay of La Ciotat in the lee of the Bec de l’Aigle. The Hyères islands offer anchorages for almost every wind, moving from one side of Porquerolles or Port-Cros to the other.
The relief often protects from the mistral, which arrives weaker and more irregular. The easterly is the main enemy: it makes most bays uncomfortable. The Lérins islands, off Cannes, and the Villefranche roadstead are the safest shelters.
The west coast is exposed to the libeccio and the mistral, which arrive after crossing the sea. The east coast, more sheltered from the west, becomes tricky in an easterly. Around Bonifacio, the strait accelerates both westerly and easterly winds: it is one of the passages to prepare most carefully, checking the bulletin just before committing to it.
Mallorca and Menorca almost always offer a sheltered coast: the south and east in a tramontane, the north in a southerly. The narrow coves, however, become rolly as soon as a swell enters, even without local wind. Mahón, at the end of a long inlet, remains one of the best shelters in the Mediterranean.
Before leaving, identify on the chart a fallback shelter for each possible wind direction, note its distance and the time you could reach it, and share this plan with your crew. If the forecast changes during the passage, you already know where to go and how many miles away it is. This is how our skippers work on every delivery: a main route, and always a fallback route to a safe shelter.
The sea is still cool and the mistral frequent, but calm days are bright and anchorages deserted. April and May offer superb sailing between two windy spells.
From June to September, the thermal breeze sets the rhythm of the days and gales become rarer. Late-summer thunderstorms can, however, bring sudden gusts: keep an eye on the sky in the afternoon.
The sea stays warm until October. Mediterranean episodes, with heavy rain and a sustained easterly, require following the bulletins closely.
The mistral and the tramontane dominate, with sometimes long episodes. Calm days between two gales are superb for a day trip, well wrapped up.

The mistral and the tramontane are the most frequent and most violent in the north-western Mediterranean. The easterly and the libeccio also raise a rough sea on exposed coasts.
From May to September, choosing a stable window of at least two days, with no mistral or strong easterly and a low residual swell. Check the offshore bulletin before leaving.
A special weather bulletin, issued by Météo-France when the wind reaches or is likely to reach force 7. It is broadcast by CROSS on VHF.
The live wind comes from the nearest station, often on land. Offshore, rely more on the Windy map and the offshore bulletin, and keep a safety margin.
