Aberystwyth harbour trap Wind Statistics, June averages since 2006
The graph shows how commonly and how strongly the wind blows from different directions through a typical June. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by the darkest shade of blue. It is based on 2303 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. 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 WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Aberystwyth harbour trap. By contrast, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average June, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 13% of the time (4 days each June) and blows offshore 24% of the time (0 days in an average June). During a typical June wind stronger than >40kph (25mph) was forecast for only a single 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.
