Agate and Pearl Street Wind Statistieken, Zomer gemiddelde vanaf 2006
The graph illustrates how commonly and how strongly the wind blows from different directions over a normal northern hemisphere summer. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by dark blue. It is based on 7266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Agate and Pearl Street, located 21 km away (13 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 dominant wind at Agate and Pearl Street blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Agate and Pearl Street. On the other hand, dominant spokes illustrate favoured directions, and the more deep 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 6% of the time (5 days each northern hemisphere summer) and blows offshore 6% of the time (5 days in an average northern hemisphere summer). Over an average northern hemisphere summer winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Agate and Pearl Street
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.
