Aberystwyth harbour trap Wind Statistics, Novembre averages since 2006
This chart illustrates how commonly and how strongly the wind blows from different directions over a normal November. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue showing the strongest winds. It is based on 2386 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Aberystwyth harbour trap, located 29 km away (18 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Aberystwyth harbour trap 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 Aberystwyth harbour trap. 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 November, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 6% of the time (2 days each November) and blows offshore 18% of the time (1 days in an average November). Over an average November winds stronger than >40kph (25mph) are expected on 6 days at Aberystwyth harbour trap
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.
