Dumps Wind Statistics, January averages since 2006
This image describes how frequently and how strongly the wind blows from different directions through a typical January. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue showing the strongest winds. It is based on 2124 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Dumps, located 23 km away (14 miles). There are insufficient 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 Dumps blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Dumps. Converseley, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average January, the model suggests that winds are light enough for the sea to be glassy (light blue) about 4% of the time (1 days each January) and blows offshore just 19% of the time (5 days in an average January). During a typical January winds stronger than >40kph (25mph) are expected on 10 days at Dumps
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.
