Potrero Grande (Ollie's Point) Surf Stats

All swells

(any wind direction)

Good Surf

(light / offshore wind)

The graph describes the combination of swells directed at Potrero Grande (Ollie's Point) over a normal March and is based upon 3460 NWW3 model predictions since 2007 (values every 3 hours). The wave model does not forecast wind or surf right at the coast so we have chosen the most applicable grid node based on what we know about Potrero Grande (Ollie's Point), and at Potrero Grande (Ollie's Point) the best grid node is 27 km away (17 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 illustrate increasing wave sizes. Blue shows the smallest swells, less that 0.5m (1.5 feet) high. These were forecast only 23% of the time. Green and yellow illustrate increasing swell sizes and highest swells greater than >3m (>10ft) are shown in red. In both graphs, the area of any colour is proportional to how commonly that size swell occurs. The diagram implies that the dominant swell direction, shown by the largest spokes, was SSW, whereas the the dominant wind blows from the NE. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Potrero Grande (Ollie's Point) and out to sea. We group these with the no surf category of the bar chart. To keep it simple we don't show these in the rose plot. Because wind determines whether or not waves are clean enough to surf at Potrero Grande (Ollie's Point), you can view an alternative image that shows only the swells that were forecast to coincide with glassy or offshore wind conditions. During a typical March, swells large enough to cause surfable waves at Potrero Grande (Ollie's Point) run for about 77% of the time.
