Agate Beach Wind Statistics, Winter averages since 2006
The rose diagram shows how commonly and how strongly the wind blows from different directions over a normal northern hemisphere winter. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 6931 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. 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 Agate Beach blows from the W. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Agate Beach. By contrast, 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 northern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 9% of the time (8 days each northern hemisphere winter) and blows offshore 35% of the time (33 days in an average northern hemisphere winter). Over an average northern hemisphere winter winds stronger than >40kph (25mph) are expected on 16 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.
