Caswell Bay Beach faces SW, straight into the prevailing Atlantic swell window — the reason it has waves at all, and the reason it is rarely flat.

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.
A sheltered, SW-facing sandy beach on the Gower Peninsula, with a beginner-friendly beach break producing lefts and rights at mid-to-high tide. Exposed to Atlantic groundswell, it's often flat in summer with better surf in winter. RNLI lifeguards patrol daily 2 May-13 September, 10:00-18:00; swim between the flags. Low tide brings a dumping wave, and rip currents are a hazard. Dogs banned 1 May-30 September.
