This picture shows how frequently and how strongly the wind blows from different directions over a normal February. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue showing the strongest winds. It is based on 1584 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Killer Point, located 26 km away (16 miles). There are insufficient 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 Killer Point blows from the NW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Killer Point. By contrast, dominant spokes represent favoured directions, and the more the darkest shade of 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 (light blue) about 16% of the time (4 days each February) and blows offshore 43% of the time (10 days in an average February). Over an average February wind stronger than >40kph (25mph) was expected for only a single days at Killer Point

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.
