It tends to rain on and off, with many cloudy days and few clear ones.

Sudden, heavy squalls are also a feature. They can turn into torrential downpours in a short time, so caution is needed.

Sun protection

Sun protection on an Okinawa trip is really important!

Getting a bright red sunburn would ruin your trip. Take thorough precautions and enjoy the beautiful scenery.

Sun protection tips

Sunscreen is a must

Choose a sunscreen of SPF50+ and PA++++, and reapply often on areas that burn easily, such as your face, neck, arms and legs. A waterproof type is recommended if you will be in the sea or a pool.

After you apply sunscreen, sweating or wiping with a towel reduces its effect, so reapply often.

Hat and sunglasses are essential

Choose a hat that covers your whole face, such as a wide-brimmed hat or a cap, and protect your eyes with sunglasses that have UV-blocking lenses.

UV rays in Okinawa are strong all year round, so for women we also recommend bringing cosmetics for skin care.

Think about your clothing too

Wear clothing that blocks the sun, such as a lightweight long-sleeved shirt or cardigan.

White and light-colored clothes reflect sunlight easily and help prevent sunburn.

Wrapping a UV-protective stole or neck guard around your neck is also effective.

A long-sleeved shirt is also handy to have.

Make use of shade

During the hours when the sun is strong, rest in the shade and look for places that shelter you from the sun, such as under trees or inside buildings.

Drink fluids often

Sunscreen washes off with sweat and water, so drinking fluids often is also important, and staying hydrated also helps release heat from your body.

Buy mineral water regularly nearby and drink it. Tap water can be a bit of a risk while traveling.

Don't forget aftercare

After a sunburn, cool and moisturize your skin to calm it. Aloe vera gel and after-sun care cream are recommended. Especially

after beach activities, you'll want to be sure you can always take care of your skin.

The sun in Okinawa is strong, so take thorough sun protection measures, and reapply sunscreen regularly as part of your skin care.
