This image shows how frequently and how strongly the wind blows from different directions over a normal year. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with deep blue showing the strongest winds. It is based on 20348 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Carlsbad City Beach, located 26 km away (16 miles). There are too few recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Carlsbad City Beach blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Carlsbad City Beach. By contrast, dominant spokes illustrate 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 year, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 20% of the time (73 days each year) and blows offshore 27% of the time (95 days in an average year). Over an average year wind stronger than >40kph (25mph) was forecast for only a single days at Carlsbad City Beach
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.
