Muriwai Beach Swell Statistics, January: Surf with Light or Offshore Winds

This image shows only the swells directed at Muriwai Beach that coincided with light winds or offshore conditions through a typical January and is based upon 2620 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 shows biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the biggest spokes, was WSW, whereas the the prevailing 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 33% of the time, equivalent to 10 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal January but 15% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 15%, equivalent to (5 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Muriwai Beach is exposed to open water swells, we estimate that clean surf can be found at Muriwai Beach about 33% of the time and that surf is spoilt by onshore wind 65% of the time. This is means that we expect 30 days with waves in a typical January, of which 10 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.
