Praia do Norte · <1 km model sample · 45% coverage
Higher bars mean a cleaner model signal
Spot intelligence.
Praia do Norte is not a normal size conversion. Canyon focusing can create much more energy than offshore height alone suggests.

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.

The break
Beach break
Advanced. Works best with W–NW swell.
Timing
E–SE offshore
Highly setup dependent. Re-check local observations and the lineup before you paddle out.
Data note
Fallback preview
Wave guidance, tide phase and offshore currents are modelled unless a nearby buoy observation is shown.
