Hammerland Wind Statistics, July averages since 2006
This image describes how commonly and how strongly the wind blows from different directions over a normal July. 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 deep blue. It is based on 2334 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Hammerland, located 45 km away (28 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 most common wind at Hammerland blows from the WSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Hammerland. 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. During a typical July, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 13% of the time (4 days each July) and blows offshore 14% of the time (4 days in an average July). Over an average July winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Hammerland
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.
