Airport Lefts Wind Statistieken, Zomer gemiddelde vanaf 2006
The figure describes how commonly and how strongly the wind blows from different directions over a normal southern hemisphere summer. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 6931 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Airport Lefts, located 33 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 Airport Lefts 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 Airport Lefts. On the other hand, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical southern hemisphere summer, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 29% of the time (26 days each southern hemisphere summer) and blows offshore 35% of the time (33 days in an average southern hemisphere summer). Over an average southern hemisphere summer winds stronger than >40kph (25mph) are expected on 3 days at Airport Lefts
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.
