Regional guidanceBali + Lesser Sunda coast guidance

Spot intelligence.

Regional guidance only: west-coast reefs favour the dry-season trades; east-coast breaks often need an early or wet-season wind window.

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.
