Baie de Kervoyal

Forecasts come from ~8 km resolution models: very local effects (a sheltering pier, a lagoon pass) are not captured.

Sea-state data comes from a marine model cell about 7.0 km from this point — local nearshore conditions can differ.

Wave heights are significant heights: individual waves up to 2× this height still occur.

Four wave models are compared for this point: EWAM, GWAM, Météo-France WAM and ECMWF WAM.

Tide times derived from modelled sea level (± a few tens of minutes) — not official tide tables.

Missing data is shown as missing — never silently estimated.
