Jack beach Swell Statistics, March: Surf with Light or Offshore Winds

This image shows only the swells directed at Jack beach that coincided with light winds or offshore conditions over a normal March. It is based on 2716 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 represent increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how frequently that size swell occurs.

The diagram suggests that the most common swell direction, shown by the largest spokes, was NW, whereas the the prevailing wind blows from the N. The chart at the bottom shows the same thing but without direction information. For$examrlu, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 29% of the time, equivalent to 9 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal March but 8% of the time we expect swell in the range 2-3m (6.5-10ft) 8%, equivalent to (2 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the fact that Jack beach is exposed to open water swells, we think that that clean surf can be found at Jack beach about 29% of the time and that surf is messed up by onshore wind 70% of the time. This is means that we expect 31 days with waves in a typical March, of which 9 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.
