On the clock
11:00 · 14:00 · 17:00 · 18:00 · 20:00
From May to September it behaves as a thermal: light until mid-morning, filling from about 11:00, strongest between 14:00 and 17:00, easing from 18:00 and largely gone by 20:00. The Scirocco and Ostro days of spring and autumn are synoptic and can blow through the night with only a small afternoon lift, so an early start is worth it out of season.
The marks are the clock times the record names, laid on a 24-hour day. The bar between the first and the last covers those hours; it is not a promise of wind.

Typical strength
Sessions here sit in a 12-18 kt band, with the harder Scirocco and Ostro afternoons pushing 18-25 kt. Modelled from ten years of hourly wind for this stretch of coast rather than a beach anemometer: afternoon hours (14:00-20:00) reach 12 kt about 29% of the time in March, 23-26% from November to February, and only 13-16% from June to September. Hours over 18 kt are rare in summer, under 2%.

The quiver, in words
For a 75-85 kg rider on a twintip: 12-14 m on the light summer thermal, 10-12 m on a normal 15-18 kt day, 8-9 m when Scirocco or Ostro is properly up at 20-25 kt. Indicative sizing read off the wind band, not from a local kit list. On gusty SE days take the smaller of two options.
Direction to shore
Scirocco (SE) arrives side-onshore and gusty at the Mignone-mouth launch. Ostro (S) is steadier but pushes rougher water onto the beach, closer to onshore. SW, W, WNW, NW: no confirmed shore angle at this exact launch.
Dominant direction
N, NNE, NE, ENE, E on the wider records; at the launch itself SE and S get the emphasis, with SW and W also named.

modelled
A weather model's cell over this place, not a station on it. Good for comparing places, weaker for one beach.
Modelled from the operational forecast archive at 1.5–7 km (2023-2024), daylight hours only, not a ground station: it resolves thermal, lake and valley winds far better than coarse reanalysis but still tends to understate a strong local thermal. A windy day has at least three consecutive daylight hours at 12 knots or more. The typical daily max and the direction are columns of the table above, month by month. Highlighted months are the riding season from the spot record.

Rider tips
- Rig at the Mignone mouth only after looking at who is in the water and reading the signage.
- Do not assume the rest of the Sant'Agostino shoreline is sand; away from the river mouth the seabed is mostly rock.
- Take the SE and S days and expect gusts when it is Scirocco.
- Keep off the beach at peak bathing hours in summer unless a kite corridor is clearly authorized.
- In summer come for the afternoon: the thermal fills after about 11:00, peaks between 14:00 and 17:00 and is finished by 20:00.
- The windiest afternoons of the year are in winter and early spring, not in the pleasant months; November to March roughly doubles the chance of a 12 kt afternoon compared with July.
