Gwithian Beach faces S, and that aspect decides whether the day's wind arrives clean off the water or broken up by the land — which matters more for windsurfing than the forecast speed alone.
Today's wind is onshore at 9 kn. Onshore is the safest direction for windsurfing here — anything that goes wrong drifts you back to the beach — at the cost of a choppier surface.
Over the published window Gwithian Beach clears 60/100 for windsurfing 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, 5 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Gwithian Beach ranks 2nd for windsurfing. 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 long, exposed Atlantic sandy beach break toward a headland, producing lefts and rights on west-northwest swells, best mid-to-low tide with offshore wind. Wide low-tide sand flats draw kitesurfers, windsurfers and kite buggies alongside surfers; often crowded. Hazards include rip currents, shifting sandbars, shorebreak at higher tide, and rocks near the headland. RNLI lifeguards patrol 5 May–30 Sept, 10am–5pm. Dogs banned 10am–6pm, 1 July–31 Aug.
