Piha North Swell Statistics, February: Surf with Light or Offshore Winds

This image shows only the swells directed at Piha North that coincided with light winds or offshore conditions through a typical February and is based upon 2664 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 represents the highest swells, greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell happens.

The diagram indicates that the dominant swell direction, shown by the longest spokes, was WSW, whereas the the dominant wind blows from the S. 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 46% of the time, equivalent to 13 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal February but 18% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 18%, equivalent to (5 days). Taking into account the fraction of these swells that coincided with predicted offshore winds, and given the fact that Piha North is exposed to open water swells, we think that that clean surf can be found at Piha North about 46% of the time and that surf is messed up by onshore wind 52% of the time. This is means that we expect 27 days with waves in a typical February, of which 13 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.
