El Porto Beach Wind Statistics, March averages since 2006
This chart describes how often and how strongly the wind blows from different directions through a typical March. The longest 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 2220 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to El Porto Beach, located 46 km away (29 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 prevailing wind at El Porto Beach blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at El Porto Beach. By contrast, dominant spokes represent favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average March, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 28% of the time (9 days each March) and blows offshore 39% of the time (11 days in an average March). In a typical March wind stronger than >40kph (25mph) was forecast for only a single days at El Porto 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.
