Hand-calibrated spot: orientation, ideal swell, tide and hazards documented. The rating still comes from a global wave model — always check on site. How we compute ratings →

From level expert · Boardshort / lycraAccessible from expert level: overhead waves (1.3–2 m), enough volume to catch them, an unforgiving reef bottom. Below that, better to aim for more modest conditions.

Today's take

Big wave, decent swell from the S. Cross-shore wind that ruffles the surface a little. Fair conditions, surfable but nothing special: fine for a practice session.
