This chart describes how frequently and how strongly the wind blows from different directions over a normal March. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with deep blue strongest. It is based on 1724 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Las Caracolas, located 19 km away (12 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 Las Caracolas 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 Las Caracolas. 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. During a typical March, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 3% of the time (1 days each March) and blows offshore just 14% of the time (4 days in an average March). Over an average March wind stronger than >40kph (25mph) was expected for only a single days at Las Caracolas

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.
