Okinawa islands in February?

Hi friends, looking for recommendations and must visits for islands in Okinawa that are nice to moped(scooter) or drive around for hidden gem beaches far from the crowd but also islands with good variety of food.

I visited xiaoliuqiu in Taiwan and thought the vibes there were great especially since I was able to explore some hidden parts of the island with a scooter.

Will be going end of February so would also like some info on how cold the water would be and how feasible it would be to explore/ go snorkeling etc

Thank you!
