Advice on weather during planned trip

We will touchdown in Naha this Sunday 8/31. We plan to be there until Saturday 9/6. However, the weather is not looking good at all. It will rain for most of our time there. We have plans to go to the Zamami island on Monday and Tokashiki Island on Tuesday. Then the rest of the trip, we plan to explore the mainland. We will be staying in Naha for our whole stay. We also have plans to rent a car.

But looking at the weather forecast, how toast are we? I’m not sure if we can reschedule. I will reach out to our airline tomorrow to see if it’s possible, if so we’ll reschedule to mid October. Is the weather going to be significantly better? Or will it be just as unpredictable?

Sort of looking for advice on what our best course of action here. We were really looking forward to spending our time on the beaches. We might just be very unlucky.
