Abereiddy Wind Statistics, Outubro averages since 2006
This image illustrates how often and how strongly the wind blows from different directions over a normal October. The longest 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 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Abereiddy, located 21 km away (13 miles). There are too few recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the prevailing wind at Abereiddy blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Abereiddy. 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. During a typical October, the model suggests that winds are light enough for the sea to be glassy (light blue) about 6% of the time (2 days each October) and blows offshore 31% of the time (4 days in an average October). Over an average October winds stronger than >40kph (25mph) are expected on 5 days at Abereiddy
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.
