North Myrtle/27th Avenue South Swell Statistics, January: Surf with Light or Offshore Winds

This image shows only the swells directed at North Myrtle/27th Avenue South that coincided with light winds or offshore conditions over a normal January. It is based on 2868 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 illustrates highest 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 largest spokes, was SSE, 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 20% of the time, equivalent to 6 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal January. Taking into account the ratio of these swells that coincided with forecast offshore winds, and given the fact that North Myrtle/27th Avenue South is exposed to open water swells, we calculate that clean surf can be found at North Myrtle/27th Avenue South about 20% of the time and that surf is blown out by onshore wind 37% of the time. This is means that we expect 18 days with waves in a typical January, of which 6 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.
