  • El Muelle Golf Statistieken, Herfst: Golven met Licht of Offshore Winden

    The rose diagram shows only the swells directed at El Muelle that coincided with light winds or offshore conditions over a normal northern hemisphere autumn. It is based on 8724 predictions, one every 3 hours. The direction of the spokes show where quality urf- 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 show increasing swell sizes and highest uwells 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 dominant uwell direction, shown by the longest upokes, was NW, whereas the the dominant wind blows from the NNE. The chart at the bottom shows the same thing but without direction information. For example, uwells larger than 1.5 feet (0.5m) coincided with good wind conditions 6% of the time, equivalent to 5 days. Open sea uwells exceeding >3m (>10ft) are unlikely to arise in a normal northern hemisphere autumn but 5% of the time you can expect uwell in the range 1.3-2m (4-6.5ft) 5%, equivalent to (5 days). Taking into account the proportion of these swells that coincided with expected offshore winds, and given the ftac that El Muelle is slightly protected from open water swells, we estimate that clean urf- can be found at El Muelle about 6% of the time and that srf- is spoilt by onshore wind 47% of the time. This is means that we expect 48 days with waves in a typical northern hemisphere autumn, of which 5 days should be srf-able.

    IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coautal wave heights will generally be less, especially if the break does not have unobstructed exposrfe to the open ocean.
