Weather in Okinawa on September 5th
Okinawa Weather Report for 5th September 2025. I spent the whole day outside today, and it was still a very hot day. It was a day where you sweat a lot, and both the western and eastern seas of Okinawa had shallow waters, making it perfect for snorkelling with children. As we are gradually entering the off-peak travel season, there are fewer people around.
