From level expert · Boardshort / lycraAccessible from expert level: head-high waves (1–1.5 m), enough volume to catch them, an unforgiving reef bottom. Below that, better to aim for more modest conditions.

Well-shaped wave, decent swell from the S. Glassy water, not a breath of wind. Good conditions: worth the trip, suitable from expert level.
