Tide source and limits

Open-Meteo marine API, Météo-France SMOC, approximately 8 km resolution. Sea level includes tides, air pressure and other ocean effects. Coastal accuracy is limited. These are model predictions, not observed readings or water depth above chart datum. The reference is global mean sea level, not lowest astronomical tide.

High and low water are estimated from neighbouring hourly samples, without minute-level interpolation. The actual turning time may fall between samples. Flat turning periods are shown as a time range; missing data and forecast edges cannot create events.

Surfing at Selong Belanak Beach

Selong Belanak Beach is the area’s main sandy-bottom beginner surf beach, with schools and board rentals along the bay. Lessons run on suitable days across the year; swell, wind and tide still change the conditions.

Plan a first surf lesson.

Planning a first surf lesson

A small offshore forecast does not tell you whether the whitewater is suitable for a first lesson. Ask an instructor to choose the time and part of the beach for your swimming confidence and experience.

Reading this forecast

Offshore waves and swell

Combined waves describe the significant offshore sea state, including swell and wind waves. Swell is shown separately with its period and source direction. Neither height is a prediction of the waves breaking on the beach.

A regional view of the coast

These three beaches share the same offshore and wind model grid cells, so their forecasts can match. Local shelter, seabed and shoreline shape can change conditions at the beach. Check conditions locally before heading into the water.

Explore nearby beaches or find local surfing and surf schools.
