Pena Roja Wind Stats

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 3224 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Pena Roja, located 18 km away (11 miles). There are insufficient recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the dominant wind at Pena Roja blows from the NW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Pena Roja. By contrast, dominant spokes show 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 July, the model suggests that winds are light enough for the sea to be glassy (light blue) about 29% of the time (9 days each July) and blows offshore 34% of the time (10 days in an average July). Over an average July wind stronger than >40kph (25mph) was expected for only a single days at Pena Roja
