Baie des Trepasses Swell Statistics, February: Surf with Light or Offshore Winds

This image shows only the swells directed at Baie des Trepasses that coincided with light winds or offshore conditions over a normal February. It is based on 2664 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow show increasing swell sizes and red shows the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the most common swell direction, shown by the largest spokes, was WSW (which was the same as the most common wind direction). 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 26% of the time, equivalent to 7 days. Open water swells exceeding >3m (>10ft) only occur 5% of the time in a typical February, equivalent to just one day but 10% of the time we expect swell in the range 2-3m (6.5-10ft) 10%, equivalent to (3 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that Baie des Trepasses is slightly protected from open water swells, we think that that clean surf can be found at Baie des Trepasses about 26% of the time and that surf is blown out by onshore wind 57% of the time. This is means that we expect 23 days with waves in a typical February, of which 7 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.
