Zarautz Wind Stats

The graph describes how often and how strongly the wind blows from different directions over a normal May. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Zarautz, located 27 km away (17 miles). There are too few recording stations world wide to use actual wind data. Invevitably some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Zarautz blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Zarautz. By contrast, dominant spokes show favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 22% of the time (7 days each May) and blows offshore 35% of the time (10 days in an average May). Over an average May wind stronger than >40kph (25mph) was expected for only a single days at Zarautz
