Tropical Trade Winds and Surfing

There is a chain of islands running from Manus Island (PNG) through to (and past) Fiji. These islands are exposed the north Pacific "winter" swell.
The part of these islands that is of interest is their north west coast. Reef passes in that part are likely to have a good wave since as the swell wraps into the pass the trade wind is off-shore.
This graphic on the surf-forecast page is the best one I have seen to show the area and the trade wind.

Look for the Orthographic Projection for SW Pacific (185°W 10°S) of wave height. Also of interest is the one for the period of the wave, the quality of the swell, its period. Longer periods mean that the swell is more powerful. These are called ground swell (wrongly) because they do not relate to the local weather condition.
