Valla Beach Wind Stats

The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue showing the strongest winds. It is based on 3471 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Valla Beach, located 42 km away (26 miles). There are not enough 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 dominant wind at Valla 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 Valla Beach. Converseley, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical October, the model suggests that winds are light enough for the sea to be glassy (light blue) about 5% of the time (2 days each October) and blows offshore 11% of the time (3 days in an average October). Over an average October winds stronger than >40kph (25mph) are expected on 2 days at Valla Beach
