Lower water exposes the sharp volcanic reef; a moving mid-to-high stage gives the wave more margin and shape.

Tides and currents use the Météo-France global ocean model via Open-Meteo at roughly 8 km resolution. Sea level includes tide and atmospheric effects and is referenced to global mean sea level, not a local chart datum. Coastal accuracy is limited; never use this for navigation.
