Ilot Sancho Wind Statistics, All Year averages since 2006
The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical year. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 21620 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Ilot Sancho, located 47 km away (29 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 most common wind at Ilot Sancho blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Ilot Sancho. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average year, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 5% of the time (18 days each year) and blows offshore 16% of the time (58 days in an average year). During a typical year winds stronger than >40kph (25mph) are expected on 3 days at Ilot Sancho
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.
