Magheraroarty Reef Wind Stats

The rose diagram shows how often and how strongly the wind blows from different directions through a typical November. The biggest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with deep blue strongest. It is based on 3347 NWW3 forecasts of wind since since 2006, at 3hr intervals, for the closest NWW3 model node to Magheroarty Reef, located 44 km away (27 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 dominant wind at Magheroarty Reef blows from the WNW. If the rose plot shows a nearly round shape, it means there is no strong bias in wind direction at Magheroarty Reef. On the other hand, 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 November, the model suggests that winds are light enough for the sea to be glassy (light blue) about 3% of the time (1 days each November) and blows offshore just 28% of the time (8 days in an average November). In a typical November winds stronger than >40kph (25mph) are expected on 10 days at Magheroarty Reef
