Portreath Beach Wind Stats

This image shows how commonly and how strongly the wind blows from different directions over a normal July. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with the strongest winds shown by dark blue. It is based on 3720 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Portreath Beach, located 30 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 Portreath Beach blows from the WNW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Portreath Beach. By contrast, dominant spokes illustrate favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. During a typical July, the model suggests that winds are light enough for the sea to be glassy (light blue) about 6% of the time (2 days each July) and blows offshore 17% of the time (1 days in an average July). Over an average July wind stronger than >40kph (25mph) was expected for only a single days at Portreath Beach
