Plage de Postolonnec faces SW, open to the prevailing swell and wind. For paddleboarding 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-onshore at 3 kn. Light enough that the surface should stay workable for paddleboarding.
Over the published window Plage de Postolonnec clears 60/100 for paddleboarding 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.

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 mixed sand-and-rock beach between two headlands in the Bay of Douarnenez, wide and sandy with shallow tidal pools at low tide, WSW-facing and designated as both a surf spot and a kitesurf zone. A municipal order currently bans swimming, nautical sports and shore fishing here due to bacteriological pollution, and the beach was rated insufficient water quality for the 2025 season. Seasonally monitored; dogs permitted; entry is only possible at low tide.
