Statistiques de Houle pour Andrew Molera State Park, Février: Vagues avec Vents Légers ou Favorables.
This image shows only the swells directed at Andrew Molera State Park that coincided with light winds or offshore conditions through a typical February and is based upon 2102 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow illustrate increasing swell sizes and red represents the highest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell happens.
The diagram indicates that the dominant swell direction, shown by the biggest spokes, was WNW, whereas the the dominant wind blows from the NNW. The chart at the bottom shows the same thing but without direction information. For example, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 44% of the time, equivalent to 12 days. Open water swells exceeding >3m (>10ft) only arise 5% of the time in a typical February, equivalent to just one day but 27% of the time we expect swell in the range 2-3m (6.5-10ft) 27%, equivalent to (8 days). Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Andrew Molera State Park is exposed to open water swells, we calculate that clean surf can be found at Andrew Molera State Park about 44% of the time and that surf is spoilt by onshore wind 55% of the time. This is means that we expect 28 days with waves in a typical February, of which 12 days should be surfable.
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.
