1. The best season for Okinawa's beaches is "until the end of October".

In Okinawa, the beach season typically runs from mid-April to October 31st, with the best time to visit being from late June (after the rainy season ends) through October.
However, this can vary slightly depending on the location, and in some cases...Beaches that are open all year round.

March, April, and November on Okinawa Island have pleasant temperatures, but compared to summer, the air and water temperatures are lower, and the daylight hours are shorter, so it's not particularly suitable for long periods of swimming.
If you're planning a trip centered around water activities outside of the peak season, it's important to limit prolonged swimming and take care not to let your body temperature drop and become ill.
Even if you have access to a suitable environment, it's wise to limit your time to short periods.

If you want to fully enjoy the ocean, consider marine activities that require wearing a wetsuit, such as snorkeling or introductory diving.
Activities involving wetsuits and drysuits are available year-round.
If you have young children, I recommend making swimming pool activities the main focus and staying at a hotel with a heated pool or indoor pool.
