In context.
A 2 km sandy beach break facing ENE, catching westerly and south-westerly swell, best September-April; rocky areas are a hazard and the spot needs significant swell to work. Kitesurfing is banned 10:00-19:30 from 15 June-15 September, otherwise permitted only below mid-tide. Dogs banned June-September. SNSM lifeguards typically cover July-August. The large tidal range, roughly 2.4-11 m, is critical; low tide suits both surf entry and kite launching.
