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 10.7 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.

Water quality · Excellent · 2025 season
Computed from the samples of the last four bathing seasons. It says what the water here has been, not what it is today: after heavy rain, even an excellent beach degrades for a day or two.

Do you know whether this beach is lifeguarded?
Reachable along the Arenella seafront, with several rocky entry points and small beach patches.
Worth knowing
The rocky seabed at Arenella hosts a quiet but rich community of small amphipod crustaceans, a sign of a healthy coastal ecosystem.
