Caerfai Beach faces SE, tucked away from the prevailing westerly swell — the aspect that gives kayaking the flat, sheltered water it needs more often than an exposed coast would.
Today's wind is cross-shore at 9 kn. At that strength expect a textured surface for kayaking, and the shelter of the bay to matter more than the forecast number.

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 compact cove beneath unstable sandstone cliffs, within a national park. Sandy at low tide, turning to rocks, boulders and pebbles with rock pools at high tide, when the beach is largely covered. The sheltered, south-east-facing bay gives a small beach-break surf for surfers, bodyboarders, sea-kayaking and coasteering; bathing water quality is rated excellent. Strong, changeable currents run offshore. No lifeguard; access is via a steep path and steps.
