Good Surf

(light / offshore wind)

This chart describes the range of swells directed at China Beach over a normal 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 most applicable grid node based on what we know about China Beach, and at China Beach the best grid node is 23 km away (14 miles). The rose diagram describes the distribution of swell sizes and swell direction, 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 35% of the time. Green and yellow illustrate increasing swell sizes and red illustrates the highest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs. The diagram implies that the most common swell direction, shown by the biggest spokes, was NE, whereas the the dominant wind blows from the ESE. Because the wave model grid is out to sea, sometimes a strong offshore wind blows largest waves away from China Beach and offshore. We combine these with the no surf category of the bar chart. To keep it simple we don't show these in the rose diagram. Because wind determines whether or not waves are good for surfing at China Beach, you can select a similar diagram that shows only the swells that were expected to coincide with glassy or offshore wind conditions. During a typical April, swells large enough to cause clean enough to surf waves at China Beach run for about 65% 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.
