Apache Pier Swell Statistics, Aprile: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Apache Pier that coincided with light winds or offshore conditions through a typical April. It is based on 2640 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 illustrate increasing swell sizes and red shows largest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how frequently that size swell happens.

The diagram suggests that the dominant swell direction, shown by the longest spokes, was SSE, whereas the the most common 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 16% of the time, equivalent to 5 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal April. Taking into account the fraction of these swells that coincided with forecast offshore winds, and given the fact that Apache Pier is exposed to open water swells, we calculate that clean surf can be found at Apache Pier about 16% of the time and that surf is blown out by onshore wind 56% of the time. This is means that we expect 22 days with waves in a typical April, of which 5 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.
