Wairoa River Mouth Swell Statistics, All Year: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Wairoa River Mouth that coincided with light winds or offshore conditions through a typical year. It is based on 34628 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 show increasing swell sizes and red illustrates 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 most common swell direction, shown by the longest spokes, was SSE, 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 29% of the time, equivalent to 106 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal year but 3% of the time we expect swell in the range 2-3m (6.5-10ft) 3%, equivalent to (11 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Wairoa River Mouth is exposed to open water swells, we think that that clean surf can be found at Wairoa River Mouth about 29% of the time and that surf is messed up by onshore wind 38% of the time. This is means that we expect 245 days with waves in a typical year, of which 106 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.
