Otago Peninsula - Boulder Beach Surf Stats

All swells

(any wind direction)

Good Surf

(light / offshore wind)

The rose diagram illustrates the combination of swells directed at Otago Peninsula - Boulder Beach through a typical March and is based upon 3460 NWW3 model predictions since 2007 (values every 3 hours). The wave model does not forecast surf and wind right at the coast so we have chosen the best grid node based on what we know about Otago Peninsula - Boulder Beach, and at Otago Peninsula - Boulder Beach the best grid node is 14 km away (9 miles). The rose diagram describes the distribution of swell sizes and directions, while the graph at the bottom shows the same thing without direction information. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. These were forecast only 29% of the time. Green and yellow show increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how frequently that size swell was forecast. The diagram suggests that the dominant swell direction, shown by the longest spokes, was S, whereas the the most common wind blows from the NW. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Otago Peninsula - Boulder Beach and out to sea. We lump these in with the no surf category of the bar chart. To avoid confusion we don't show these in the rose plot. Because wind determines whether or not waves are surfable at Otago Peninsula - Boulder Beach, you can view an alternative image that shows only the swells that were predicted to coincide with glassy or offshore wind conditions. Over an average March, swells large enough to cause good for surfing waves at Otago Peninsula - Boulder Beach run for about 71% of the time.
