Haven't seen the Sailing Weather - Marine Weather Forecasts for Sailors and Adventurers - PassageWeather site before. Thanks for that reference!
Depends where you are in Tahiti, never been there but they have some of the most powerful waves in the world at Tahiti's Teahupo'o. These waves are generated in the Southern Ocean I believe.

Also, the sea breezes near land are actually thermal driven (not low pressure areas over an island). The land heats the air which rises and needs to be replaced by the cooler air over the ocean- then the air blows from ocean to the land- usually in late morning or afternoon until sunset.)
