Balephuil (Tiree) Swell Statistics, All Year: All Swell – Any Wind

The figure shows the range of swells directed at Balephuil (Tiree) through an average year and is based upon 28044 NWW3 model predictions since 2006 (values every 3 hours). The wave model does not forecast wind and surf right at the coast so we have chosen the optimum grid node based on what we know about Balephuil (Tiree). In the case of Balephuil (Tiree), the best grid node is 5 km away (3 miles).

The rose diagram shows the distribution of swell directions and swell sizes, while the graph at the bottom shows the same thing without direction information. Five colours represent increasing wave sizes. Very small swells of less than 0.5m (1.5 feet) high are shown in blue. These were forecast only 20% of the time. Green and yellow show 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 often that size swell happens.

The diagram indicates that the prevailing swell direction, shown by the largest spokes, was WSW, whereas the the prevailing wind blows from the SW. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Balephuil (Tiree) and out to sea. We group these with the no surf category of the bar chart. To avoid confusion we don't show these in the rose diagram. Because wind determines whether or not waves are clean enough to surf at Balephuil (Tiree), you can load a different image that shows only the swells that were forecast to coincide with glassy or offshore wind conditions. In a typical year, swells large enough to cause surfable waves at Balephuil (Tiree) run for about 80% of the time.

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.
