Okinawa questions

Hey guys,
I’m currently in Japan on vacation and was planning a few days in Okinawa.
I was told to be careful about the weather on the island these days so I’m now hesitant about going there.
I’ve seen many weather reports and they are all different.
Some say it’s gonna rain all week long, others say that there will be a lot of sunny days.

How’s the weather been lately and what do you recommend ?
Also I don’t have a driving licence so I can’t rent a car, how easy or hard is it gonna be for me to go around ?

Thank you so much !
