Kontxa Hondartza 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-shore at 3 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 Kontxa Hondartza 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, 10 of 10 daylight hours clear that line at Intermediate.
Among the 31 scored spots within reach today, Kontxa Hondartza ranks 8th 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 sheltered bay beach, roughly 1,350m of sandy, gently shelving shore. An exposed sandy beach break with inconsistent surf and both left and right peaks, working best on a northwest groundswell wrapping into the bay with offshore south wind. Calmer and softer-breaking than a nearby beach, it suits beginner surfing and bodyboarding, plus swimming, paddleboarding and kayaking.
