Dumps Wind Statistics, January averages since 2006
This image illustrates how commonly and how strongly the wind blows from different directions through a typical January. The biggest 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 strongest. It is based on 2372 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 too few recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Dumps blows from the WNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Dumps. By contrast, dominant spokes show 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 18% 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.
