This picture describes how frequently and how strongly the wind blows from different directions through a typical April. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue showing the strongest winds. It is based on 1646 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Playa de Suesto, located 32 km away (20 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 prevailing wind at Playa de Suesto blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Playa de Suesto. Converseley, 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 April, the model suggests that winds are light enough for the sea to be glassy (light blue) about 7% of the time (2 days each April) and blows offshore 15% of the time (2 days in an average April). During a typical April winds stronger than >40kph (25mph) are expected on 3 days at Playa de Suesto
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.
