Where to stay and transportation

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.

The best diving season in Okinawa

Diving is possible throughout the year in Okinawa, but the top season is July, August, and September when the sun is shining. It is also typhoon season, with at least three typhoons per month approaching close to the main island of Okinawa and affecting diving.Underwater temperatures range from 18 to 30 degrees Celsius, and in mid-summer, divers can dive in shorts only.Okinawa’s climate is characterized by a high pressure pattern in the west and a low pressure pattern in the east, so in winter, from November to April, the winds are mostly from the north, and from May to October, the winds are from the south.Most of the dive sites in Okinawa are located on the western coast, and because of the slanting shape of the islands, the best wind direction for diving is from the south or east.
When sea conditions are not good, it is when north or west winds are blowing.May and June are the rainy season. but no worry because it doesn’t matter in the sea, but it is a little disappointing because it rains all the time when you come on vacation.

The best dive sites based on the weather forecast

We look at the weather forecast to suggest the best dive sites. Wind direction is especially important!
We usually choose to dive in the shade of an island on the opposite side of the island, where the wind blows. For example, if the wind is blowing from the east, we will go to the dive site on the west side because the island will block the wind.

And most of the dive sites on the main island of Okinawa are located on the west side. If the wind blows from the east or south, you can go to most of the dive sites. Japan has a westerly high and easterly low pressure pattern. Northerly winds are common in winter and southerly winds are common in summer.
