Good Surf

(light / offshore wind)

The rose diagram describes the range of swells directed at Pentewan through an average April. It is based on 3120 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 most applicable grid node based on what we know about Pentewan. In the case of Pentewan, the best grid node is 35 km away (22 miles). The rose diagram describes the distribution of swell directions and swell sizes, while the graph at the bottom shows the same thing but without direction information. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. These occurred only 93% 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 often that size swell occurs. The diagram indicates that the most common swell direction, shown by the biggest spokes, was SSE, whereas the the dominant wind blows from the NW. Because the wave model grid is offshore, sometimes a strong offshore wind blows largest waves away from Pentewan and away from the coast. We combine these with the no surf category of the bar chart. To simplify things we don't show these in the rose graph. Because wind determines whether or not waves are surfable at Pentewan, you can view an alternative image that shows only the swells that were forecast to coincide with glassy or offshore wind conditions. In a typical April, swells large enough to cause good for surfing waves at Pentewan run for about 3% of the time.

We hope you find the new 12-day forecasts and additional details useful.

Kudos to everyone who helped us debug this over the past 3 months.

Be sure to click on the Advanced Surf option to see extra details about the sea-state. Look out for crossing swells and short period local wind swells and chop that will often spoil a groundswell even if the wind is perfect. As yet there is no allowance for this in the swell rating. This is something we are working on.
