Day scores here are the conditions out of 80; a trip's score on the results is the same conditions out of 100. The journey never scores. The forecast reaches about 10 days. Energy is the swell's power in kJ per metre of wave, from its height and interval: it grows with the square of each, so a long-period swell hits far harder than a short one the same size. Wind is in knots: 10 kn is about 19 km/h. The arrow points where the wind blows to; offshore wind, blowing from the land out to sea, is green and says so.
