Occurrence of each Hs/Tp pair over 4 years of hourly data off Ushant: the reference table for characterising a site's sea state.
35,000 hours of sea states (Open-Meteo marine, 2022-2025) aggregated into 0.5 m × 1 s classes. Hover over a cell to read the exact occurrence of the (Hs, Tp) pair: this is the first deliverable a structural engineer or an operator asks for when characterising a site.
