Tide curve (forecast)
-3.6 ftrising
Northwest swell is the cleanest trigger, southwest can still work, and southeast wind is preferred.
Low tide is the best window, though mid and high can still give good surfing if the beach has shape.
The beach is long enough to pick a section, but strong rips can develop along it.
Rio Sieira and As Furnas sit side by side in Porto do Son, so the beach is best read as a local surf zone rather than a single tiny peak.
