Dominican Republic

Two Septembers out there. Mornings held both times. Weather built after two most days. Swap to the morning boat if they will let you. Afternoon and sunset sailings are the first ones moved.

First week of September 2024 for us, nine days, and we lost one boat day. Rain arrived about 3pm and had gone by 6 most afternoons, so we swam in the morning and put lunch and a nap in the wet part. The thing I would check before worrying any further is the reschedule window on what you have already paid, and whether your travel insurance counts weather as a covered reason. That mattered to us more than any forecast did. We also left the last day of the trip empty, which is where the boat would have moved to if it had gone.

You are getting the kind version of September in this thread. I had the other one. Second week, two years ago, three days out of five where it rained from eleven until dark and both water days got pushed to the end. I went back the following year, so it did not put me off. What I would actually change is the position of it in your week. Do not put the boat on the last day. Buy it early so there is somewhere for it to move to.
