The Balearic Islands sit in the western Mediterranean between mainland Spain and Sardinia — a position that exposes them to both the summer thermal winds of the Mediterranean and the occasional violent Tramontana from the north. The sailing is generally straightforward with well-marked harbours and clear water, but the passages between islands (40–80M) require active weather planning, and the summer ferry traffic in the inter-island channels demands vigilance at night.
The Tramontana
The Tramontana is a cold, dry north-westerly gale that descends from the Pyrenees and accelerates into the Balearics from the north. It is most frequent in winter and spring but can occur from October to May. Unlike the Meltemi (which is thermally driven and predictable), the Tramontana is synoptically driven — it arrives with the passage of a cold front and can reach Force 8–10 with little warning once established. Signs: a rapid fall in temperature, clearing skies and improved visibility (the air is exceptionally dry), and a north-westerly shift in the gradient wind. Check the AEMET (Spanish Met Office) marine forecast before any passage from October to May; the Tramontana is one of the weather events that kills sailors in the Balearics.
Inter-Island Passages
Palma to Ibiza (80M south-west): the main offshore passage in the Balearics. The channel is exposed to north-west swell in any Tramontana. Time the passage for the middle of the day to use the sea breeze; the approach to Ibiza Town or Eivissa in the evening light is rewarding. Mallorca to Menorca (80M north-east): use the northern route via Cap de Formentor for the scenic approach. Palma to Cabrera (25M south): a day sail to the national park island — the anchorage in the natural harbour is spectacular and access requires a pre-booking of the anchorage permit through the park authority.
Ferry Traffic
The Balearic inter-island ferry routes are among the busiest in the Mediterranean — Trasmediterranea and Balearia run high-speed ferries between Palma, Ibiza, Menorca, and mainland Barcelona and Valencia. These vessels travel at 30+ knots and generate a significant wake. At night, the ferry lanes (which broadly follow the main inter-island passages) require a proper watch — a vessel approaching at 30 knots gives you very little time to take avoiding action once identified on AIS. Keep AIS running and maintain a proper radio watch on VHF 16 in the inter-island channels.
Key Harbours: Entry Notes
Palma: large commercial and recreational port, well marked, accessible day or night. The Real Club Náutico de Palma is the main visitor marina (VHF 9); Port Adriano (15M south-west) has better facilities for larger yachts. Port de Pollença (north Mallorca): sheltered, well marked, ferry terminal on the east side of the entrance. Ciudadella, Menorca: narrow entrance, well marked, fits about 30 visiting yachts stern-to on the main quay. The entrance canal is 200m long and 30m wide — enter and exit with engine only and be aware of the ferry that uses the same entrance.
Frequently Asked Questions
Q: Are the Balearic anchorages free?
A: Most of the smaller coves and bays are free to anchor. The main exceptions are national park areas — Cabrera National Park requires a pre-booked anchorage permit (free, booked through the Spanish parks service). Some popular bays in Mallorca (Formentor, Cala d'Or) now charge anchoring fees through a private concession during summer. Always check with the local harbour authority before anchoring in an area you have not visited before.
Q: Is the Tramontana forecastable?
A: Yes, but you need to check the right sources. AEMET's marine forecast (specifically the METEOCAT area forecast covering the western Mediterranean) gives 48-hour predictions for Tramontana events. Windguru and Windy both carry the GFS and ECMWF models for the area. If the forecast shows strong northerlies at 900hPa over the Gulf of Lion, a Tramontana is coming — get into a harbour with good holding and wait it out.
