The Okinawan sea can be enjoyed throughout the year, but the scenery and creatures you can encounter differ greatly depending on the time of year.
Here are some of the best times of year to visit, depending on your objectives: "I want to see the best scenery," "I want to avoid the crowds," "I want to see certain creatures," and so on.
May-August
The best season for a dynamic "summer

This is the royal season for snorkeling, when the Okinawan sea is at its most brilliant.
From the end of the rainy season (usually around late June), the contrast between the bright blue sky and emerald green ocean is at its most beautiful, and bright light shines even into the water.
The spawning season for coral and sea turtles begins around May. Fish become more active, and you can observe a wide variety of marine life, including brightly colored tropical fish, shellfish, and mollusks.
Note that popular spots can be very crowded with tourists. Aim for early morning or other times of the day, or make reservations in advance.
October - April
Enjoy the silence and transparency of "Autumn and Winter".
