With that being said we can look at how the climate changes and what the best time is to visit the island for sun, sea and diving.
Since Okinawa is located on a latitude of 36° 00′ Northern degrees, which makes it a sub-tropical location. This benefits the weather all year around and provides lots of sun every day. The temperature isn’t really changing all year around since the seasons don’t have as many impact as in the rest of Japan. Okinawa experiences average temperatures of 15-20 degrees in the winter months from November-December and 25-30 degrees in the other months. The hottest month is definitely July and August, the temperature rises above the 30 degrees on most of the days. Therefore, Japan has divided the seasons of Okinawa in warm and cold season.
