Hi Becky and welcome!
As far as weather, I think it is pretty common to see the forecast calling for rain since it's a tropical climate and rain is always a possibility. However, it seems that even with the "weather" calling for rain, I think you'll find you'll have more sun. But then again, it's really hard to predict what the weather will actually be like for your trip... we can only hope
