Today plus the next two days are free for everyone — scored in 3-hour windows, just like the app. The full 8-day forecast lives in the 4Shor app.
Lido Altamarea faces SW, open to the prevailing swell and wind. For swimming that is the hard direction: expect the surface to be workable only when the forecast genuinely drops, not on an average day.
Today's wind is cross-shore at 10 kn. At that strength expect a textured surface for swimming, and the shelter of the bay to matter more than the forecast number.
Over the published window Lido Altamarea clears 60/100 for swimming at every ability from Beginner to Expert — an unusually broad spot, which normally means a range of conditions rather than one narrow sweet spot. Today, 4 of 10 daylight hours clear that line at Intermediate.
Among the 29 scored spots within reach today, Lido Altamarea is level with 3 others at the top for swimming — nothing nearby is scoring better, so pick on distance.
Satellite-derived bathymetry with 10 m pixels and 10 cm vertical resolution out to ~40 m depth. The shape of the seabed is what determines where and how waves break.
Most apps run a single global model at 9–25 km. We blend regional NWP from national meteorological offices at 1.3–2 km — UK Met Office UKV, Météo-France AROME HD, ItaliaMeteo ICON-2I — with ECMWF IFS for the 8-day horizon. Finer resolution means the sea breeze, cliff funnelling and bay shadowing that changes everything for a session.
A nearshore wave model propagates the spectrum across the bathymetric mesh — modelling refraction, shoaling, dissipation, focusing and breaking as it goes. Most apps stop at swell + wind. We go further.
10 sport models × 4 ability levels weight wave height, period, wind, tide and breaking conditions differently — calibrated against ridden sessions so the scores mean what they say.
A private paid beach club on a fine, gently shelving sandy stretch of the Tyrrhenian coast, with calm, shallow, clear water suited to swimming and family bathing rather than watersports. Kitesurfing is banned here during the bathing season, permitted only on weekdays in May, June and September; windsurfing is zoned away from bathing areas. Lifeguards are required at one per 80 m of beachfront during the official bathing season.
