Estadísticas de Olas para The Breakwater-St Ives, abril: Olas con Vientos Ligeros o Terrales

The rose diagram shows only the swells directed at The Breakwater-St Ives that coincided with light winds or offshore conditions through a typical April and is based upon 2880 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 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 happens.

The diagram implies that the prevailing swell direction, shown by the largest spokes, was W, whereas the the most common wind blows from the NNW. 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 20% of the time, equivalent to 6 days. Open water swells exceeding >3m (>10ft) only arise 1.8% of the time in a typical April, equivalent to just one day but 7% of the time we expect swell in the range 2-3m (6.5-10ft) 7%, equivalent to (2 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that The Breakwater-St Ives is slightly protected from open water swells, we estimate that clean surf can be found at The Breakwater-St Ives about 20% of the time and that surf is spoilt by onshore wind 30% of the time. This is means that we expect 15 days with waves in a typical April, of which 6 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.
