Capitola Rivermouth Swell Statistics, Winter: Surf with Light or Offshore Winds

This image shows only the swells directed at Capitola Rivermouth that coincided with light winds or offshore conditions over a normal northern hemisphere winter and is based upon 8485 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 show increasing swell sizes and red represents the biggest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell was forecast.

The diagram suggests that the prevailing swell direction, shown by the biggest spokes, was WSW, whereas the the prevailing wind blows from the N. 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 0.1% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal northern hemisphere winter. Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Capitola Rivermouth is quite sheltered from open water swells, we think that that clean surf can be found at Capitola Rivermouth about 0.1% of the time and that surf is messed up by onshore wind 1.9% of the time. This is means that we expect 2 days with waves in a typical northern hemisphere winter, of which 0 days should be clean enough to surf.

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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
