Agate Beach Wind Statistics, Autumn averages since 2006
This picture shows how often and how strongly the wind blows from different directions over a normal northern hemisphere autumn. The largest 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 7252 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Agate Beach, located 38 km away (24 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 Agate Beach blows from the W. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Agate Beach. By contrast, dominant spokes show favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical northern hemisphere autumn, the model suggests that winds are light enough for the sea to be glassy (light blue) about 11% of the time (10 days each northern hemisphere autumn) and blows offshore 27% of the time (24 days in an average northern hemisphere autumn). Over an average northern hemisphere autumn winds stronger than >40kph (25mph) are expected on 9 days at Agate Beach
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.
