Spot intelligence.
Boneyards is the upper ledge of the main point. On a lined-up swell it can hand waves into Supertubes, but the take-off is shallow and highly committed.

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.
