Alofau Gas Station Swell Statistics, Summer: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Alofau Gas Station that coincided with light winds or offshore conditions over a normal southern hemisphere summer and is based upon 8485 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow represent increasing swell sizes and red represents the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the prevailing swell direction, shown by the largest spokes, was SW, whereas the the prevailing wind blows from the ENE. 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 12% of the time, equivalent to 11 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal southern hemisphere summer but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (3 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Alofau Gas Station is exposed to open water swells, we calculate that clean surf can be found at Alofau Gas Station about 12% of the time and that surf is blown out by onshore wind 6% of the time. This is means that we expect 16 days with waves in a typical southern hemisphere summer, of which 11 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.
