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

The rose diagram shows only the swells directed at Upham Beach that coincided with light winds or offshore conditions through a typical May. It is based on 2690 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 represent increasing swell sizes and red shows the largest swells, greater than >3m (>10ft). In each graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the most common swell direction, shown by the biggest spokes, was SSW, whereas the the most common wind blows from the NNE. 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 1.8% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal May. Taking into account the fraction of these swells that coincided with expected offshore winds we calculate that clean surf can be found at Upham Beach about 1.8% of the time and that surf is messed up by onshore wind 15% of the time. This is means that we expect 5 days with waves in a typical May, 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.
