Carlsbad City Beach Wind Statistics, All Year averages since 2006
The rose diagram describes how commonly and how strongly the wind blows from different directions over a normal year. The longest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue showing the strongest winds. It is based on 22223 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 insufficient 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 prevailing wind at Carlsbad City Beach blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Carlsbad City Beach. By contrast, dominant spokes represent favoured directions, and the more dark 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 (the lightest shade of 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 expected 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.
