Back Strands Swell Statistics, Gennaio: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Back Strands that coincided with light winds or offshore conditions through a typical January and is based upon 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 show increasing swell sizes and red illustrates largest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the dominant swell direction, shown by the longest spokes, was W, whereas the the most common wind blows from the SW. 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 34% of the time, equivalent to 11 days. Open water swells exceeding >3m (>10ft) only occur 4% of the time in a typical January, equivalent to just one day but 20% of the time we expect swell in the range 2-3m (6.5-10ft) 20%, equivalent to (6 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Back Strands is slightly protected from open water swells, we calculate that clean surf can be found at Back Strands about 34% of the time and that surf is spoilt by onshore wind 56% of the time. This is means that we expect 28 days with waves in a typical January, of which 11 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.
