Estadísticas de Olas para Anna Bay-Morna Point, enero: Olas con Vientos Ligeros o Terrales
This image shows only the swells directed at Anna Bay-Morna Point that coincided with light winds or offshore conditions through a typical January and is based upon 2372 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. Green and yellow represent increasing swell sizes and biggest swells greater than >3m (>10ft) are shown in red. In either graph, the area of any colour is proportional to how frequently that size swell happens.
The diagram suggests that the most common swell direction, shown by the longest spokes, was ESE, whereas the the prevailing wind blows from the E. 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 35% of the time, equivalent to 11 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal January 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 Anna Bay-Morna Point is slightly protected from open water swells, we think that that clean surf can be found at Anna Bay-Morna Point about 35% of the time and that surf is spoilt by onshore wind 24% of the time. This is means that we expect 18 days with waves in a typical January, of which 11 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.
