Where to stay and transportation
Okinawa main island is big more than you think
If you are going to activities or sightseeing other than diving, a car is strongly recommended.
(You cannot hire a car without an international driving licence, so please get one before you go.
It is possible to travel by public bus, but it probably takes twice as long as by car. There is no train service, but there is a monorail only near Naha.
See next page for accommodation with free transport.
The best diving season in Okinawa
The great thing about Okinawa is that you can enjoy diving all year round! Each season offers something different, making Okinawa an exciting destination for divers throughout the year.
Summer (July – September)
Summer is the most popular diving season in Okinawa, with plenty of sunshine, warm tropical waters, and excellent opportunities to explore the underwater world.
Water temperatures can reach 28–30°C, making it possible to dive comfortably with minimal exposure protection.
Summer is also typhoon season, and tropical storms can occasionally affect diving schedules. However, with flexible planning and a variety of dive sites around the island, there are often alternative options depending on sea conditions.
Spring & Autumn (April – June / October – November)
Spring and autumn are fantastic times to visit Okinawa, offering pleasant temperatures and generally fewer visitors than the peak summer months.
May and June are typically the rainy season, but rain itself rarely affects the underwater experience. You can still enjoy beautiful dives even on cloudy or rainy days!
October and November can also offer warm water and excellent diving opportunities as the seasons change.
Winter (December – March)
Winter brings a completely different side of Okinawa's underwater world.
Although the water temperature can drop to around 18–22°C, diving is still possible throughout the winter with appropriate exposure protection.
Winter is also a wonderful time for divers who prefer quieter dive sites and a more relaxed atmosphere.
Understanding Okinawa's Sea Conditions
Okinawa's diving conditions are influenced mainly by seasonal wind patterns.
From around November to April, northerly winds are more common, while southerly winds generally prevail from May to October.
Many popular dive sites are located along Okinawa's west coast, where southerly and easterly winds often provide favorable conditions.
When winds and waves make certain sites unsuitable, we do our best to recommend alternative locations based on the day's conditions.
No matter when you visit Okinawa, there's always something worth exploring underwater!
Every season has its own highlights, and we're happy to help you choose the best dive sites for your experience level, interests, and the conditions during your stay.
