Snorkeling and sailing in Ishigaki in early November – safe or not?

I previously made a post about visiting Ishigaki in early November, and thanks to the great feedback, we decided to go ahead and book the trip!

We’re now looking into activities and really want to go snorkling, but I’ve heard many companies stop offering these activities after October. One company mentioned that the strong north winds often lead to ferry cancellations and that snorkeling tours are generally rare in late October/early November.

I’m still looking for options but wondering if snorkeling and sailing in Ishigaki and the nearby islands are less safe or reliable in early November due to the winds?

Any tips or experiences you can share would be greatly appreciated! 🙏🏼
