Staircase Beach Wind Statistics, Autumn averages since 2006
This image illustrates how commonly 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 indicates the strength, with deep blue showing the strongest winds. It is based on 5837 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Staircase Beach, located 7 km away (4 miles). There are too few 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 Staircase Beach blows from the SW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Staircase Beach. Converseley, 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 34% of the time (31 days each northern hemisphere autumn) and blows offshore 57% of the time (5 days in an average northern hemisphere autumn). Over an average northern hemisphere autumn winds exceeding >40kph (25mph) are not expected, but 1 have winds on the range 30-40 (19-25) at Staircase 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.
