Aticama Wind Stats

The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical May. The biggest 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 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Aticama, located 31 km away (19 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 dominant wind at Aticama blows from the SSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Aticama. By contrast, dominant spokes represent favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average May, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 49% of the time (15 days each May) and blows offshore 60% of the time (17 days in an average May). During a typical May winds exceeding >40kph (25mph) are not expected, but 0 have winds on the range 30-40 (19-25) at Aticama
