Plage Hérel faces SW, open to the prevailing swell and wind. For swimming that is the hard direction: expect the surface to be workable only when the forecast genuinely drops, not on an average day.
Today's wind is cross-shore at 7 kn. Light enough that the surface should stay workable for swimming.
Over the published window Plage Hérel clears 60/100 for swimming 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, 10 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Plage Hérel ranks 6th for swimming. 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 coarse-sand beach at the foot of a marina, facing southwest into one of Europe's most extreme tidal environments, with spring tides reaching 13.4 m. A boat-launch ramp and pebbly sections line the shore; an adjacent nautical base runs windsurfing, paddle and catamaran sessions from a sheltered retention pond, not the open beach. At low tide the foreshore is largely exposed, making entry difficult; mid-to-high tide is best. The beach is unsupervised.
