From level expert · Boardshort / lycraAccessible from expert level: head-high waves (1.1–1.7 m), enough volume to catch them, a long, powerful swell (12 s) that pushes hard, an unforgiving reef bottom. Below that, better to aim for more modest conditions.

Today's take

Well-shaped wave, nice long, clean swell from the SW. Slightly side-offshore wind, fairly favourable. Good conditions: worth the trip, suitable from expert level.
