Drumnacraig Beach Swell Statistics, Gennaio: Surf with Light or Offshore Winds

This image shows only the swells directed at Drumnacraig Beach that coincided with light winds or offshore conditions over a normal January. It is based on 2868 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. Green and yellow represent increasing swell sizes and red shows biggest swells greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell occurs.

The diagram indicates that the most common swell direction, shown by the longest spokes, was NNW, 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 0.8% of the time, equivalent to 0 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal January. Taking into account the ratio of these swells that coincided with predicted offshore winds, and given the fact that Drumnacraig Beach is exposed to open water swells, we estimate that clean surf can be found at Drumnacraig Beach about 0.8% of the time and that surf is blown out by onshore wind 3% of the time. This is means that we expect 1 days with waves in a typical January, of which 0 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.
