Treasure Island Wind Statistics, Spring averages since 2006

The graph describes how frequently and how strongly the wind blows from different directions over a normal northern hemisphere spring. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the strongest winds shown by deep blue. It is based on 5802 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Treasure Island, located 22 km away (14 miles). There are not enough 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 dominant wind at Treasure Island blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Treasure Island. Converseley, dominant spokes represent 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 spring, the model suggests that winds are light enough for the sea to be glassy (light blue) about 55% of the time (50 days each northern hemisphere spring) and blows offshore 73% of the time (2 days in an average northern hemisphere spring). Over an average northern hemisphere spring winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Treasure Island

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.
