Galveston Wind Stats

The graph illustrates how often and how strongly the wind blows from different directions over a normal October. The largest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue showing the strongest winds. It is based on 3218 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Galveston, located 34 km away (21 miles). There are too few 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 prevailing wind at Galveston blows from the SE. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Galveston. By contrast, dominant spokes illustrate 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 October, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 8% of the time (2 days each October) and blows offshore 18% of the time (2 days in an average October). Over an average October winds exceeding >40kph (25mph) are not expected, but 2 have winds on the range 30-40 (19-25) at Galveston
