How is the weather in Ishigaki and Miyako in early October?

I went to ishigaki in 2023 around April and the weather was sunny every day, it was my favourite part of my japan trip and I thought the food was incredible.

I'm planning to do a mini trip to Ishigaki and Miyako islands between October 1-7 and was wondering how the weather usually is during this period of the year. Haven't booked anything yet, so open to suggestions and other islands as well.

Thanks!
