Japan's southernmost prefecture, Okinawa was an independent kingdom called Ryukyu from the 15th to 19th centuries, trading with China, Japan, and Southeast Asia. The islands saw the bloodiest battle of the Pacific War in 1945. Okinawa is one of the world's 'Blue Zones' — regions with exceptional longevity — attributed to the traditional diet, strong community ties, and active outdoor lifestyle.
Nights sit around 27°C and afternoons around 31°C.
The year in Okinawa moves gently: summer afternoons sit around 31°C, winter ones around 21°C.
Some winter nights drop to 12°C.
Most of the rain falls in summer, least in winter. In June it rains about 16 days in 30; in February, 9.
Wind is a factor: June averages 20 km/h, enough to notice on a terrace or a bike. Air quality is worth watching: March averages an AQI of 59, while September clears to 40.
Days stretch to about 13.6 hours of light in June and shrink to 10.4 in December — something to weigh if you work to a fixed timezone.
No month in Okinawa matches what you're after, so come for the place rather than the weather. Expect fast internet (164 Mbps) and a high cost of living (about €1600 a month).
