Traeth Crigyll faces SW, straight into the prevailing Atlantic swell window — the reason it has waves at all, and the reason it is rarely flat.
Today's wind is cross-offshore at 6 kn. Leaning offshore, so the face should still stand up clean for surfing — not the glassy hold of a straight offshore, but the right side of neutral.

Satellite-derived bathymetry with 10 m pixels and 10 cm vertical resolution out to ~40 m depth. The shape of the seabed is what determines where and how waves break.
Most apps run a single global model at 9–25 km. We blend regional NWP from national meteorological offices at 1.3–2 km — UK Met Office UKV, Météo-France AROME HD, ItaliaMeteo ICON-2I — with ECMWF IFS for the 8-day horizon. Finer resolution means the sea breeze, cliff funnelling and bay shadowing that changes everything for a session.
A nearshore wave model propagates the spectrum across the bathymetric mesh — modelling refraction, shoaling, dissipation, focusing and breaking as it goes. Most apps stop at swell + wind. We go further.
10 sport models × 4 ability levels weight wave height, period, wind, tide and breaking conditions differently — calibrated against ridden sessions so the scores mean what they say.
This is a wide, south-west-facing sandy beach, primarily fine golden sand with rocky outcrops near town and an offshore reef, best known for kitesurfing and windsurfing rather than reliable surf. Beach-break peaks form mid-beach, working only when a SW or W swell threads a narrow gap offshore, an infrequent alignment. A river mouth at the south end creates a rip hazard, especially on an outgoing tide. There is no lifeguard; dogs are permitted year-round.
