Trebarwith Beach faces NW, 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 7 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.
Over the published window Trebarwith Beach clears 60/100 for surfing at every ability from Beginner to Expert — an unusually broad spot, which normally means a range of conditions rather than one narrow sweet spot. Today, 9 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Trebarwith Beach ranks 2nd for surfing. The order changes by discipline: the same conditions that put a spot top for one sport can drop it down the list for another.
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 tide-dominated Atlantic beach break flanked by slate cliffs and sea caves, with sand present only at low to mid tide and none at high water. Two sandbanks give lefts and rights, with a powerful, shallow inner bank; larger swells close out the beach. Dangerous rip currents are a recognised hazard, and access is via a rocky gulley that floods quickly on a rising tide. RNLI lifeguards patrol daily in summer.
