Joluchuca Swell Statistics, January: Surf with Light or Offshore Winds

This image shows only the swells directed at Joluchuca that coincided with light winds or offshore conditions through a typical January. It is based on 2620 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 highest swells greater than >3m (>10ft) are shown in red. In either 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 largest spokes, was SSW, whereas the the dominant 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 50% of the time, equivalent to 16 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal January but 7% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 7%, equivalent to (2 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Joluchuca is exposed to open water swells, we calculate that clean surf can be found at Joluchuca about 50% of the time and that surf is blown out by onshore wind 29% of the time. This is means that we expect 24 days with waves in a typical January, of which 16 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.
