How to read this report

• Wave height. It is the real height at the beach, not the open-sea swell: each beach has its own factor, because the same swell does not break the same at San Juan de Nieva as at the beach next door.
• Period. The seconds between two waves. It is the most underrated number: at the same size, a long period brings waves with power and shape, a short one brings them messy.
• Wind. Always in knots. What matters is not the strength but the direction: blowing from land to sea (offshore) it grooms the wave, from sea to land it messes it up.
• Tide. In metres. Every beach has its good window, and outside it the same day can go from surfable to useless in two hours.
• AI score. A score from 0 to 5 given by a model trained on real ratings of sessions at this very beach — not a generic formula. When the day is bad it says so, which is the point.
