As best as I can tell, Bonaire is pretty constant the year round. A little more rain at times and temps vary a little but not by much. If you have some specific questions, may I suggest you drop by my other haunt http://www.BonaireTalk.com/newsgroup/messages/board-topics.html I can promice that any question on Bonaire can be answered there. There are several on island members as well as a bunch of long time visitors. The most striking thing about Bonaire that totally caught me off guard on my first visit was the terrain, I guess I expected lush, tropical (Gilligans Island) but it actually is quite arrid, more like an Arizona desert, cactus, lizzards, goats and donkeys everywhere. It has it's own unique beauty, can't wait to get back.
