Mouse Rock Wind Statistics, April averages since 2006
The figure shows how frequently and how strongly the wind blows from different directions through a typical April. The longest 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 strongest. It is based on 1680 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 not enough 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 most common wind at Mouse Rock blows from the WNW. If the rose graph shows a fairly circular pattern, 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 deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average April, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 8% of the time (2 days each April) and blows offshore 10% of the time (3 days in an average April). In a typical April 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.
