Jelly Babies Swell Statistics, May: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Jelly Babies that coincided with light winds or offshore conditions over a normal May. It is based on 2696 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 highest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the dominant swell direction, shown by the longest spokes, was SSW, whereas the the dominant wind blows from the SSE. 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 56% of the time, equivalent to 17 days. Open water swells exceeding >3m (>10ft) only happen 2% of the time in a typical May, equivalent to just one day but 21% of the time we expect swell in the range 2-3m (6.5-10ft) 21%, equivalent to (7 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Jelly Babies is exposed to open water swells, we calculate that clean surf can be found at Jelly Babies about 56% of the time and that surf is blown out by onshore wind 44% of the time. This is means that we expect 31 days with waves in a typical May, of which 17 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.
