Sentinel (South Andaman) Wind Stats

The figure describes how often and how strongly the wind blows from different directions through a typical May. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with dark blue strongest. It is based on 3422 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Sentinel (South Andaman), located 26 km away (16 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3. According to the model, the prevailing wind at Sentinel (South Andaman) blows from the SW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Sentinel (South Andaman). By contrast, dominant spokes show favoured directions, and the more deep 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 (light blue) about 17% of the time (5 days each May) and blows offshore 28% of the time (1 days in an average May). In a typical May winds stronger than >40kph (25mph) are expected on 2 days at Sentinel (South Andaman)
