Mundaka Wind Statistics, January averages since 2006
The rose diagram describes how frequently and how strongly the wind blows from different directions through a typical January. The longest spokes point in the directions the wind most commonly blows from and the shade of blue suggests the strength, with the darkest shade of blue strongest. It is based on 1925 NWW3 forecasts of wind since since 2007, at 3hr intervals, for the closest NWW3 model node to Mundaka, located 19 km away (12 miles). There are not enough recording stations world wide to use actual wind data. No doubt some coastal places have very localized wind effects that would not be predicted by NWW3.
According to the model, the dominant wind at Mundaka blows from the NW. If the rose graph shows a fairly circular pattern, it means there is no strong bias in wind direction at Mundaka. Converseley, dominant spokes show 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 13% of the time (4 days each January) and blows offshore 49% of the time (11 days in an average January). During a typical January winds stronger than >40kph (25mph) are expected on 3 days at Mundaka
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.
