Don't worry about the weather MiketheKid, because lots of time it won't last for very long.
I remember a couple of years ago, we hit cloudy and showery conditions on our first day at sea and it followed us from island to island the whole week. It only showered once that I can think of but the temps were warm and we were on vacation being pampered...It didn't bother our vacation or the plans we had from island to island. We had new cruisers with us and thought that it would dampen there cruising but they were hooked.
Enjoy the time !
