Legend & notes
The Mediterranean wind rose
The direction the wind blows from. The percentages are the share of hours it blows from each sector.
The boat profiles
The profile changes the thresholds for "ideal conditions": the same month can be ideal for an experienced crew and demanding for a sailing school.
Source. ERA5 reanalysis (10 m wind, air temperature) and the Open-Meteo wave model (wave height/direction/period, sea temperature), hourly extraction for the Apr–Oct season, Europe/Rome time zone. 2021 is excluded because it has no wave data; sea temperature starts in 2023 (2022 has none).
How to read it. With "All years" you see the 2022–2025 average (a climate statistic, not a forecast); with a single year you see how that season went. "Good days" are days with ≥4 daytime hours (10–18) in the ideal or lively band, according to the selected boat profile. Reanalysis wind tends to smooth out local peaks: at sea, gusts can be slightly higher. Directions are where the wind comes from.
At sea. No historical data replaces the forecast bulletin and direct observation.
