Algarrobo Wind Statistics, Winter averages since 2006
This image shows how frequently and how strongly the wind blows from different directions through a typical southern hemisphere winter. The largest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 7266 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Algarrobo, located 39 km away (24 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 most common wind at Algarrobo blows from the SW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Algarrobo. Converseley, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average southern hemisphere winter, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 13% of the time (12 days each southern hemisphere winter) and blows offshore 22% of the time (20 days in an average southern hemisphere winter). In a typical southern hemisphere winter winds stronger than >40kph (25mph) are expected on 5 days at Algarrobo
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.
