Caerfai Bay Wind Stats

The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies 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 Caerfai Bay, located 22 km away (14 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 most common wind at Caerfai Bay blows from the WSW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Caerfai Bay. On the other hand, dominant spokes illustrate favoured directions, and the more dark blue, the stronger the wind. Spokes point in the direction the wind blows from.

Over an average May winds stronger than >40kph (25mph) are expected on 2 days at Caerfai Bay
