If you are an expert rider, go to Maui, I am sure there are greatest waves in the world.
If you are new to wave-riding, my home spot is very friendly to beginner. Here is a picture of my wave riding last week.

Wind is very good here from Oct. to April, usually 25 -40 knot. It's side-on shore wind, you always get back on shore.
The best month is Oct.- Dec.
