Good Surf

(light / offshore wind)

This picture illustrates the range of swells directed at Raiven through a typical April, based on 3360 NWW3 model predictions since 2007 (values every 3 hours). The wave model does not forecast wind and surf right at the coastline so we have chosen the optimum grid node based on what we know about Raiven, and at Raiven the best grid node is 17 km away (11 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 42% of the time. Green and yellow illustrate increasing swell sizes and largest swells greater than >3m (>10ft) are shown in red. In each 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 longest spokes, was SSE, whereas the the most common wind blows from the W. Because the wave model grid is offshore, sometimes a strong offshore wind blows largest waves away from Raiven 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 good for surfing at Raiven, 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 April, swells large enough to cause clean enough to surf waves at Raiven run for about 0% 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.
