Annascaul Rivermouth Wind Statistieken, September gemiddelde vanaf 2006
This picture illustrates how frequently and how strongly the wind blows from different directions through a typical September. The largest spokes point in the directions the wind most commonly blows from and the shade of blue implies the strength, with dark blue strongest. It is based on 2400 NWW3 forecasts of wind since since 2006, 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. 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 Annascaul Rivermouth blows from the WSW. If the rose diagram shows a close to circular outline, it means there is no strong bias in wind direction at Annascaul Rivermouth. Converseley, dominant spokes show favoured directions, and the more deep blue, the stronger the wind. Spokes point in the direction the wind blows from. Over an average September, the model suggests that winds are light enough for the sea to be glassy (the lightest shade of blue) about 4% of the time (1 days each September) and blows offshore just 11% of the time (1 days in an average September). During a typical September winds stronger than >40kph (25mph) are expected on 3 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.
