Caister-on-Sea Swell Statistics, Summer: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Caister-on-Sea that coincided with light winds or offshore conditions through a typical northern hemisphere summer and is based upon 8735 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 largest swells greater than >3m (>10ft) are shown in red. In each graph, the area of any colour is proportional to how commonly that size swell was forecast.

The diagram implies that the prevailing swell direction, shown by the longest spokes, was N, whereas the the most common wind blows from the WSW. 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 1.2% of the time, equivalent to 1 days. Open sea swells exceeding >3m (>10ft) are unlikely to occur in a normal northern hemisphere summer. Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Caister-on-Sea is slightly protected from open water swells, we estimate that clean surf can be found at Caister-on-Sea about 1.2% of the time and that surf is messed up by onshore wind 5% of the time. This is means that we expect 5 days with waves in a typical northern hemisphere summer, 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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
