Polzeath Wind Stats

The figure illustrates how often and how strongly the wind blows from different directions over a normal May. The longest 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 strongest. It is based on 3440 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Polzeath, located 47 km away (29 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 dominant wind at Polzeath blows from the W. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Polzeath. Converseley, dominant spokes illustrate favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical May, the model suggests that winds are light enough for the sea to be glassy (light blue) about 9% of the time (3 days each May) and blows offshore 28% of the time (2 days in an average May). Over an average May winds stronger than >40kph (25mph) are expected on 2 days at Polzeath
