El Martillo Swell Statistics, Summer: Surf with Light or Offshore Winds

This image shows only the swells directed at El Martillo that coincided with light winds or offshore conditions over a normal southern hemisphere summer and is based upon 6931 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow represent increasing swell sizes and red represents the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the dominant swell direction, shown by the biggest spokes, was SE, whereas the the most common wind blows from the E. 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 14% of the time, equivalent to 13 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal southern hemisphere summer. Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that El Martillo is exposed to open water swells, we think that that clean surf can be found at El Martillo about 14% of the time and that surf is messed up by onshore wind 65% of the time. This is means that we expect 72 days with waves in a typical southern hemisphere summer, of which 13 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.
