Calafia Swell Statistics, July: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Calafia that coincided with light winds or offshore conditions through a typical July and is based upon 2976 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 highest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the dominant swell direction, shown by the biggest spokes, was SSW, whereas the the dominant wind blows from the WNW. 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 74% of the time, equivalent to 23 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal July but 21% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 21%, equivalent to (7 days). Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Calafia is exposed to open water swells, we calculate that clean surf can be found at Calafia about 74% of the time and that surf is blown out by onshore wind 11% of the time. This is means that we expect 26 days with waves in a typical July, of which 23 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.
