Gilligans Swell Statistics, Dicembre: Surf with Light or Offshore Winds

This image shows only the swells directed at Gilligans that coincided with light winds or offshore conditions through a typical December and is based upon 2953 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 biggest 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 SSW, whereas the the prevailing 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 40% of the time, equivalent to 12 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal December but 14% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 14%, equivalent to (4 days). Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that Gilligans is exposed to open water swells, we estimate that clean surf can be found at Gilligans about 40% of the time and that surf is blown out by onshore wind 60% of the time. This is means that we expect 30 days with waves in a typical December, of which 12 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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
