Plage de Rochanic faces N. Which swells reach it — and therefore whether there is anything worth riding — depends on that aspect more than on the open-ocean forecast height.
Today's wind is cross-shore at 8 kn. Straight cross-shore sits between the two for surfing — the face stays rideable but the wall is less organised than on a clean offshore.
Over the published window Plage de Rochanic 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, 6 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Plage de Rochanic ranks 20th 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 small, sheltered north-facing sandy cove backed by a nautical school, classed as flat water for windsurfing and wingfoil rather than a surf spot — sailing, kayaking, SUP and wingfoiling are the main uses. At high water the beach is fine sand, but at low tide, especially on large coefficients, it can nearly disappear, revealing a rocky shelf and mooring buoys. Supervised bathing runs July and August only; dogs are banned mid-June to mid-September.
