Mouse Rock Wind Statistics, May averages since 2006
The graph illustrates how commonly and how strongly the wind blows from different directions over a normal May. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the darkest shade of blue showing the strongest winds. It is based on 1736 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Mouse Rock, located 50 km away (31 miles). There are insufficient 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 most common wind at Mouse Rock 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 Mouse Rock. On the other hand, 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 7% of the time (2 days each May) and blows offshore 8% of the time (2 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 3 days at Mouse Rock
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.
