Annascaul Rivermouth Wind Statistics, January averages since 2006
The figure shows how commonly and how strongly the wind blows from different directions through a typical January. The largest 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 2372 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Annascaul Rivermouth, located 35 km away (22 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 prevailing wind at Annascaul Rivermouth blows from the WSW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Annascaul Rivermouth. By contrast, 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 January, the model suggests that winds are light enough for the sea to be glassy (pale blue) about 3% of the time (1 days each January) and blows offshore just 9% of the time (2 days in an average January). In a typical January winds stronger than >40kph (25mph) are expected on 9 days at Annascaul Rivermouth
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.
