James stevens weighs up the options:
Lampaul is exposed to wind and swell coming in from south and west. It’s also prone to poor visibility as the incoming warmer, more humid southwesterly winds pass over cooler European waters.
With this forecast he should leave as soon as is prudent – first light the next day, as night pilotage in strong tides around this area is tricky, and they’ve already had a busy night crossing the Channel. Heading for Audierne is tricky with a strong southwesterly coming in. The Raz de Sein requires precise navigation and tidal planning, and going round the outside of the outlying rocks adds both distance and a hard beat. My preference would be to bear away for the uncluttered approach to the Baie de Douarnenez, finishing up in Douarnenez itself. This is a safe and lovely place to rest, and still makes a satisfying step on the route south.
With hindsight, Lampaul wasn’t the best place to stop. It does illustrate the importance of looking at a sequence of synoptic charts before heading off to get a clearer idea the overall movement of weather systems for your planned trip.
