Weather in Okinawa

Summer days are sunny and winter days are cloudy.

Summer rains are like squalls, with large amounts of rain falling in a short period of time. Even with a high probability of precipitation, there are surprisingly long periods of clear skies.

From June to October, many typhoons arrive. Since typhoons are a natural phenomenon and difficult to avoid, it is important to prepare for them by watching the weather forecast.

Typhoons in Okinawa are stronger than those in mainland Japan, so be careful. Umbrellas are difficult to use because they are easily damaged. If going out on foot, it is advisable to prepare a raincoat.

Also, be aware that accidents occur every year in which doors are agitated by strong winds and fingers and other objects are caught in door gaps, resulting in serious injury.

If you are in Okinawa when the typhoon arrives, it is generally safer not to go outside.

Clothing in Okinawa

Because of the warm temperatures, short sleeves are fine from May to November, while long sleeves or a light coat is advisable from December to March.

In summer, the sun is very strong and sunburn protection is necessary. Sunscreen and rash guards are essential, especially when swimming at the beach.

In addition, it is very hot and humid during the rainy season in May and June, so it is advisable to bring a large change of clothes.

Even in winter, there are days when the temperature difference between day and night is large, and on such days you can spend the day in short sleeves.

If you plan to visit the seaside area in winter, it is better to bring a heavy coat because it is windy and cold along the seaside.

Okinawa Sea Opening

The ocean opens in March on some beaches. However, the water temperature is low in March and not very suitable for swimming.

The ideal time to enjoy swimming is from May to October.
