This picture describes how commonly and how strongly the wind blows from different directions over a normal northern hemisphere summer. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 5065 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Hossegor - La Nord, located 37 km away (23 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.

According to the model, the prevailing wind at Hossegor - La Nord blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Hossegor - La Nord. On the other hand, dominant spokes illustrate 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 northern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 20% of the time (18 days each northern hemisphere summer) and blows offshore 29% of the time (25 days in an average northern hemisphere summer). Over an average northern hemisphere summer winds stronger than >40kph (25mph) are expected on 2 days at Hossegor - La Nord

IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
