Kaifu Rivermouth Swell Statistics, July: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Kaifu Rivermouth that coincided with light winds or offshore conditions through a typical July. It is based on 2480 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 shows highest 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 biggest spokes, was SE, whereas the the dominant wind blows from the SSW. 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 3% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal July. Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that Kaifu Rivermouth is slightly protected from open water swells, we think that that clean surf can be found at Kaifu Rivermouth about 3% of the time and that surf is spoilt by onshore wind 16% of the time. This is means that we expect 6 days with waves in a typical July, of which 1 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.
