Spot intelligence.
Impossibles is named for its speed. Long-period, perfectly angled swell gives the best chance of linking this section instead of watching it outrun the rider.

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.
