El Mongol Swell Statistics, November: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at El Mongol that coincided with light winds or offshore conditions through a typical November. It is based on 2387 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 show increasing swell sizes and red illustrates the biggest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how commonly that size swell happens.

The diagram implies that the most common swell direction, shown by the longest spokes, was NW, whereas the the prevailing wind blows from the W. 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 25% of the time, equivalent to 8 days. Open water swells exceeding >3m (>10ft) only arise 2% of the time in a typical November, equivalent to just one day but 15% of the time we expect swell in the range 2-3m (6.5-10ft) 15%, equivalent to (4 days). Taking into account the proportion of these swells that coincided with forecast offshore winds, and given the fact that El Mongol is slightly protected from open water swells, we think that that clean surf can be found at El Mongol about 25% of the time and that surf is blown out by onshore wind 58% of the time. This is means that we expect 25 days with waves in a typical November, of which 8 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.
