Wind bar: the month's model mean wind between 09:00 and 18:00 against the windiest month here (full bar). Model rows: daytime (09:00 to 18:00) means; a windy day has 2 hours or more at the sport's minimum; a surf day 2 daylight hours of waves of 0.5 m or more; sunny: daytime cloud 30 % or less; rain: 1 mm or more.

From weather models 2021 to 2025. At spots with thermal wind or sea breeze the model reads several knots low; the bars show the shape of the year, riders know the numbers.
