(any wind direction)

The graph describes how often and how strongly the wind blows from different directions through a typical March. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the strongest winds shown by dark blue. It is based on 3460 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Port Isabel, located 22 km away (14 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 most common wind at Port Isabel blows from the E. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Port Isabel. Converseley, dominant spokes show favoured directions, and the more dark 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 (light blue) about 3% of the time (1 days each March) and blows offshore just 4% of the time (1 days in an average March). During a typical March wind stronger than >40kph (25mph) was forecast for only a single days at Port Isabel
