The figure shows 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 implies the strength, with deep blue showing the strongest winds. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Bertha's Beach, located 29 km away (18 miles). There are not enough 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 prevailing wind at Bertha's Beach blows from the SSE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Bertha's Beach. Converseley, dominant spokes show 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 (light blue) about 2% of the time (1 days each May) and blows offshore just 51% of the time (16 days in an average May). In a typical May winds stronger than >40kph (25mph) are expected on 7 days at Bertha's Beach
