The biggest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by the darkest shade of blue. It is based on 3506 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Pors Poulhan, located 3 km away (2 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 prevailing wind at Pors Poulhan blows from the W. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Pors Poulhan. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from.

In a typical June wind stronger than >40kph (25mph) was expected for only a single days at Pors Poulhan
