This chart illustrates how often 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 implies the strength, with the darkest shade of blue showing the strongest winds. It is based on 1728 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to LancesLeft, located 21 km away (13 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 dominant wind at LancesLeft blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at LancesLeft. Converseley, 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. Over an average January, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 37% of the time (11 days each January) and blows offshore 90% of the time (28 days in an average January). During a typical January winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at LancesLeft
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.
