Arinaga Wind Statistics, July averages since 2006
The figure illustrates how frequently and how strongly the wind blows from different directions through a typical July. 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 deep blue. It is based on 2480 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Arinaga, located 42 km away (26 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 Arinaga blows from the N. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Arinaga. On the other hand, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average July, the model suggests that winds are light enough for the sea to be glassy (light blue) about 0% of the time (0 days each July) and blows offshore just 0.3% of the time (0 days in an average July). During a typical July winds stronger than >40kph (25mph) are expected on 2 days at Arinaga
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.
