This image shows only the swells directed at El Golfo that coincided with light winds or offshore conditions over a normal June. It is based on 1600 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 represent increasing swell sizes and red represents highest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell happens.
The diagram suggests that the most common swell direction, shown by the largest spokes, was NW, whereas the the dominant 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 3% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal June. Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that El Golfo is exposed to open water swells, we think that that clean surf can be found at El Golfo about 3% of the time and that surf is messed up by onshore wind 40% of the time. This is means that we expect 13 days with waves in a typical June, of which 1 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.
