Forecasts come from ~8 km resolution models: very local effects (a sheltering pier, a lagoon pass) are not captured.
Sea-state data comes from a marine model cell about 5.7 km from this point — local nearshore conditions can differ.
Wave heights are significant heights: individual waves up to 2× this height still occur.
Four wave models are compared for this point: EWAM, GWAM, Météo-France WAM and ECMWF WAM.
Tide times derived from modelled sea level (± a few tens of minutes) — not official tide tables.
Missing data is shown as missing — never silently estimated.

Official sampling is weekly at best; between two samples, recent rain is the recognized warning signal (EEA)

Do you know whether this beach is lifeguarded?
The beach can be reached from the coastal road running along Castelvetrano's shoreline.
Worth knowing
The ghost crab (Ocypode cursor) recorded along this shore is a rare Mediterranean species more typical of North African coasts, a small sign of how mild this stretch of Sicily's climate really is.
