Lackan Bay Wind Statistics, December averages since 2006
This picture describes how frequently and how strongly the wind blows from different directions through a typical December. The biggest 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 the darkest shade of blue. It is based on 2209 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Lackan Bay, located 30 km away (19 miles). There are too few 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 Lackan Bay blows from the NW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Lackan Bay. Converseley, dominant spokes represent favoured directions, and the more the darkest shade of blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average December, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 3% of the time (1 days each December) and blows offshore just 35% of the time (10 days in an average December). During a typical December winds stronger than >40kph (25mph) are expected on 7 days at Lackan Bay
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.
