Upham Beach Swell Statistics, Summer: Surf with Light or Offshore Winds

This image shows only the swells directed at Upham Beach that coincided with light winds or offshore conditions through a typical northern hemisphere summer and is based upon 8722 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 represents largest swells greater than >3m (>10ft). In each 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 SW (which was the same as the most common wind direction). 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 2.0% of the time, equivalent to 2 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere summer. Taking into account the ratio of these swells that coincided with predicted offshore winds we calculate that clean surf can be found at Upham Beach about 2.0% of the time and that surf is messed up by onshore wind 15% of the time. This is means that we expect 15 days with waves in a typical northern hemisphere summer, of which 2 days should be clean enough to surf.

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.
