Gileston Wind Stats

This image describes how often and how strongly the wind blows from different directions through a typical September. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 3358 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Gileston, located 43 km away (27 miles). There are insufficient 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 Gileston blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Gileston. On the other hand, 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. Over an average September, the model suggests that winds are light enough for the sea to be glassy (light blue) about 10% of the time (3 days each September) and blows offshore 20% of the time (0 days in an average September). In a typical September winds stronger than >40kph (25mph) are expected on 2 days at Gileston
