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 remote, uncrowded Blue Flag beach on the northern Inishowen Peninsula, facing NNE into the North Atlantic, within a Special Area of Conservation. The sandy beach break gives left and right-handers, rated beginner-friendly, most consistent in winter (especially November); summer is calmer and mostly flat, suiting swimming too. Rocky headlands divide the beach and are hazardous at low tide. Lifeguards are on duty weekends in June and daily July-August.
