snorkeling in Okinawa late November

I've seen some posts of people recommending some cool places to snorkel in Okinawa and they look amazing.

Anyone know if Blue Cave would be too cold to snorkel in right now when the weather will get up to 25 degrees Celsius this weekend?

EDIT: Thank you everyone that have given their experiences and advice! Sounds like it's still awesome to snorkel during the month of November here. I'm excired to go this weekend! Appreciate everyone's time 🙏
