Statistiques de Vent de Annascaul Rivermouth, moyennes sur Été depuis 2006
The graph shows how often and how strongly the wind blows from different directions over a normal northern hemisphere summer. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue showing the strongest winds. It is based on 7266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Annascaul Rivermouth, located 35 km away (22 miles). There are too few recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Annascaul Rivermouth blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Annascaul Rivermouth. 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 (light blue) about 5% of the time (5 days each northern hemisphere summer) and blows offshore 14% of the time (2 days in an average northern hemisphere summer). Over an average northern hemisphere summer winds stronger than >40kph (25mph) are expected on 5 days at Annascaul Rivermouth
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.
