Coolum Beach Wind Statistics, June averages since 2006
This picture illustrates how commonly and how strongly the wind blows from different directions over a normal June. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue indicates the strength, with the darkest shade of blue showing the strongest winds. It is based on 2074 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Coolum Beach, located 41 km away (25 miles). There are insufficient recording stations world wide to use actual wind data. Without question some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the most common wind at Coolum Beach blows from the SE. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Coolum Beach. 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 June, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 10% of the time (3 days each June) and blows offshore 45% of the time (14 days in an average June). Over an average June winds stronger than >40kph (25mph) are expected on 2 days at Coolum Beach
IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
