Zmudowski State Beach Swell Statistics, Spring: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Zmudowski State Beach that coincided with light winds or offshore conditions over a normal northern hemisphere spring. It is based on 8682 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 shows largest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the prevailing swell direction, shown by the longest spokes, was WNW, whereas the the most common wind blows from the NW. 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 23% of the time, equivalent to 21 days. Open water swells exceeding >3m (>10ft) only happen 1.3% of the time in a typical northern hemisphere spring, equivalent to just one day but 9% of the time we expect swell in the range 2-3m (6.5-10ft) 9%, equivalent to (8 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Zmudowski State Beach is exposed to open water swells, we calculate that clean surf can be found at Zmudowski State Beach about 23% of the time and that surf is blown out by onshore wind 67% of the time. This is means that we expect 82 days with waves in a typical northern hemisphere spring, of which 21 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.
