The Mediterranean is famous for its calm waters, but it can change mood fast! Understanding the weather forecast isn't just checking whether it's sunny. It means knowing the local winds (Tramontana, Mistral) and knowing when it's better to stay in port.
Reliable Sources
- AEMET (Spain's State Meteorological Agency): the official forecast is the single most important source of information.
- Specific apps and websites: Windfinder, Windy, or the Institut d'Estudis Catalans (IEC) for wave forecasts in Catalonia.
Catalonia's Local Hazards
- Tramontana: A strong, cold wind from the north. It builds short, choppy seas along the Costa Brava. If it's blowing, it's best to shelter to leeward (to the south).
- Mistral/Mestral: A northwesterly (NW) wind. Strong and dry, common on the Costa Daurada.
- Levante: An easterly (E) wind. Brings humidity and usually generates a heavy swell. Watch out for this one!
The Decision Rule (Wind Strength)
For a PNB/PER holder on a small boat, sailing continuously in Force 5 winds (17-21 knots) or above isn't advisable for a leisure outing. If waves of 2 metres or more are forecast, it's better to postpone the trip.
Study the weather!
The weather module is key in the exam. Don't cut corners — learn the Beaufort scale! (Course run in Spanish.) See PER Syllabus
