As May arrives, Okinawa gradually begins to show signs of the rainy season. Since travel schedules are easily affected by the weather, some people may feel anxious about whether they can still enjoy a trip to Okinawa during this time.
This time, we'll introduce the timing of the rainy season in Okinawa, its weather characteristics, clothing tips, and ways to enjoy sightseeing even on rainy days.

1. After Golden Week, Okinawa will enter the rainy season.

The rainy season in Okinawa typically begins around May 10th, but the actual start date varies greatly from year to year.

近年の実績を見ると、2024年は5月21日頃、2026年は5月4日頃と、同じ5月でも10日以上前後する年もあります。過去には、4月下旬に梅雨入りした年や6月にずれ込んだ年もあり、毎年ほぼ同じ時期とは限りません。
Therefore, if you're planning a trip to Okinawa from late May onwards, it's a good idea to factor in the possibility of the rainy season starting when planning your itinerary.

The rainy season ends in late June or July.

The rainy season in Okinawa typically ends around June 21st.
The rainy season typically ends in late June or early July, marking the start of full-fledged summer, but this period is also characterized by significant year-to-year variations.

Most recently, the rainy season ended around June 20th in 2024, which was about average, while in 2025 it ended very early, around June 7th. In the past, there have been years when the rainy season continued until early July, so the timing of the end of the rainy season is not consistent every year.
When planning a trip to Okinawa in late June, keep in mind that while you might experience sunny weather right after the end of the rainy season, there are also years when rain lingers.

2. What is the weather like during the rainy season in Okinawa?

The rainy season in Okinawa is incredibly humid; just stepping outside makes your clothes feel like they're sticking to your skin. It's muggy and hot, and the high temperatures mean you're drenched in sweat.
However, it's not like it rains lightly all day long; more often than not, it rains heavily, then stops, then rains again, and so on.

Weather forecasts are often wrong. You might think, "It's sunny today, so it should be fine, I'll hang out the laundry," and then suddenly a heavy downpour starts. On the other hand, sometimes sunny days continue as soon as the rainy season begins, making you wonder, "Is it really the rainy season now?"
Since the weather is so unpredictable, I often check weather forecast apps before going out and decide what to do next.

Clothing and belongings for a trip to Okinawa during the rainy season

In Okinawa during the rainy season, it's recommended to wear clothing that can handle both the humid heat and sudden downpours.
It's very humid and damp, so breathable clothing like a T-shirt and shorts, or a knee-length, easy-to-move-in dress will keep you comfortable. If your clothes are water-repellent, you won't have to worry about them getting a little wet.
On the other hand, shops and cars can be quite cold due to air conditioning, so it's a good idea to bring a light jacket or cardigan. Also, bring a slightly larger towel in case you get wet in the rain!
For your feet, sandals are convenient because you don't have to worry about them getting wet. Rain boots are also a good option depending on your outfit.

Incidentally, in Okinawa, many residents wear island sandals regardless of the season. Recently, there are stylish island sandals with great designs, and even fashionable ones that you can customize yourself, so it's worth checking them out when you visit!
Also, since UV rays are strong even on rainy days, sunscreen is an item you should have with you regardless of the weather. On sunny days, the sun is especially strong, so we recommend bringing a hat and sunglasses as well.
If you don't mind carrying extra luggage, it's a good idea to bring a folding umbrella. A dual-purpose umbrella that works for both sun and rain is convenient not only for sun protection but also for unexpected downpours.

3. If it's sunny, you're lucky! If you're traveling to Okinawa during the rainy season, have an "alternative plan" ready.

When people think of traveling to Okinawa during the rainy season, they often imagine it's not fun because of all the rain. However, it's not all bad. After Golden Week, airfares are often a little cheaper, which is a big advantage as it makes it easier to keep travel expenses down.
Even during the rainy season, it doesn't rain all day long, and there are days when the sun comes out and you can swim in the sea. However, it's difficult to predict the weather and sea conditions until the last minute, and swimming may be prohibited suddenly. That's why it's a good idea to have an alternative plan in case it rains.

Indoor facilities where you can have fun even on rainy days include Churaumi Aquarium, DMM Kariyushi Aquarium, Okinawa World, Fruit Land, and Nago Pineapple Park. Unless it's pouring rain all day, you can still enjoy sightseeing around Kokusai Street. The shopping streets in the back alleys are covered by arcades, so you can enjoy eating and exploring Okinawa without an umbrella.
There are plenty of other spots you can enjoy even on rainy days. Plan your trip so that it's not too dependent on the weather, and enjoy a unique Okinawa trip during the rainy season.
