Balnakiel Bay Swell Statistics, Winter: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at Balnakiel Bay that coincided with light winds or offshore conditions through a typical northern hemisphere winter. It is based on 8485 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 red represents biggest swells greater than >3m (>10ft). In either graph, the area of any colour is proportional to how often that size swell was forecast.

The diagram indicates that the prevailing swell direction, shown by the biggest spokes, was NW, 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 15% of the time, equivalent to 14 days. Open water swells exceeding >3m (>10ft) only occur 1.4% of the time in a typical northern hemisphere winter, equivalent to just one day but 7% of the time we expect swell in the range 2-3m (6.5-10ft) 7%, equivalent to (6 days). Taking into account the fraction of these swells that coincided with expected offshore winds, and given the fact that Balnakiel Bay is slightly protected from open water swells, we estimate that clean surf can be found at Balnakiel Bay about 15% of the time and that surf is spoilt by onshore wind 65% of the time. This is means that we expect 73 days with waves in a typical northern hemisphere winter, of which 14 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.

FEATURE UPDATE: we now show red swell icons for 'open sea' swells that are travelling in an unfavourable direction for the surf break. In places, these swells may still wrap around coastlines and produce smaller waves at some breaks. They are also significant for windsurfers and other water users that tend to venture further off-shore.
