Statistiques de Houle pour Machir Bay (Islay), Novembre: Vagues avec Vents Légers ou Favorables.

This image shows only the swells directed at Machir Bay (Islay) that coincided with light winds or offshore conditions through a typical November. It is based on 2387 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 illustrate 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 often that size swell happens.

The diagram indicates that the dominant swell direction, shown by the longest spokes, was W, whereas the the prevailing wind blows from the SW. 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 17% of the time, equivalent to 5 days. Open sea swells exceeding >3m (>10ft) are unlikely to arise in a normal November but 5% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 5%, equivalent to (2 days). Taking into account the ratio of these swells that coincided with expected offshore winds, and given the fact that Machir Bay (Islay) is exposed to open water swells, we think that that clean surf can be found at Machir Bay (Islay) about 17% of the time and that surf is spoilt by onshore wind 70% of the time. This is means that we expect 26 days with waves in a typical November, of which 5 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.
