Good Surf

(light / offshore wind)

The figure shows the combination of swells directed at Cancas through an average April. It is based on 3360 NWW3 model predictions since 2007 (values every 3 hours). The wave model does not forecast wind and surf right at the coast so we have chosen the most applicable grid node based on what we know about Cancas. In this particular case the best grid node is 60 km away (37 miles). The rose diagram shows the distribution of swell sizes and directions, while the graph at the bottom shows the same thing but lacks direction information. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. These happened only 70% of the time. Green and yellow represent increasing swell sizes and red represents the biggest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how often that size swell happens. The diagram indicates that the most common swell direction, shown by the largest spokes, was WSW, whereas the the prevailing wind blows from the SSW. Because the wave model grid is away from the coast, sometimes a strong offshore wind blows largest waves away from Cancas 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 diagram. Because wind determines whether or not waves are good for surfing at Cancas, 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 clean enough to surf waves at Cancas run for about 29% 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.
