Aberystwyth harbour trap Wind Statistics, All Year averages since 2006
This chart illustrates how frequently and how strongly the wind blows from different directions through a typical year. The biggest 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 28031 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 not enough 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 dominant wind at Aberystwyth harbour trap blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aberystwyth harbour trap. Converseley, dominant spokes represent 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 year, the model suggests that winds are light enough for the sea to be glassy (light blue) about 8% of the time (29 days each year) and blows offshore 21% of the time (7 days in an average year). During a typical year winds stronger than >40kph (25mph) are expected on 40 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.
