Well, that is on the windward side which gets the most rainfall on the island. That is why it's so green and lush!! In January you have a good chance of getting some of our winter storms too. Very different than the typical trade showers. Or, it could be nice and sunny most of the time. The trade showers are short in duration, happen mainly in the early morning/late evening hours.
Thanks. Are you familiar with the paradise bay resort?
I've heard about it, seen the web-site a while back but no, I'm not "familiar" with it.
