Alize Swell Statistics, Maggio: Surf with Light or Offshore Winds

This image shows only the swells directed at Alize that coincided with light winds or offshore conditions over a normal May and is based upon 2200 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 illustrate increasing swell sizes and red represents the biggest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the dominant swell direction, shown by the largest spokes, was ENE, whereas the the prevailing wind blows from the ESE. 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 5% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal May. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Alize is exposed to open water swells, we calculate that clean surf can be found at Alize about 5% of the time and that surf is messed up by onshore wind 94% of the time. This is means that we expect 31 days with waves in a typical May, of which 2 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.
