This chart shows how commonly and how strongly the wind blows from different directions over a normal northern hemisphere winter. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 5048 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Newcombs Hollow, located 5 km away (3 miles). There are not enough 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 Newcombs Hollow blows from the NE. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Newcombs Hollow. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical northern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 3% of the time (3 days each northern hemisphere winter) and blows offshore just 16% of the time (14 days in an average northern hemisphere winter). Over an average northern hemisphere winter winds stronger than >40kph (25mph) are expected on 7 days at Newcombs Hollow
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.
