Aberystwyth harbour trap Wind Statistics, Fevereiro averages since 2006
This chart describes how commonly and how strongly the wind blows from different directions over a normal February. The longest 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 2101 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Aberystwyth harbour trap, located 29 km away (18 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 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. 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. During a typical February, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 5% of the time (1 days each February) and blows offshore 25% of the time (1 days in an average February). Over an average February winds stronger than >40kph (25mph) are expected on 4 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.
