Atacames Wind Statistics, January averages since 2006
The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical January. The longest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with dark blue strongest. It is based on 2372 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Atacames, located 23 km away (14 miles). There are insufficient 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 Atacames blows from the WNW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Atacames. On the other hand, 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. Over an average January, the model suggests that winds are light enough for the sea to be glassy (light blue) about 10% of the time (3 days each January) and blows offshore 18% of the time (6 days in an average January). During a typical January winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Atacames
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.
