Monthly Average Temperatures in Okinawa

Okinawa enjoys a warm, subtropical climate; winters are pleasantly mild, and summers are refreshingly breezy, making it a popular summer retreat. Since the weather is comfortable year-round, it’s a great place to visit any time of year. This climate is one of Okinawa’s many charms. *The table shows average values for Naha City from 1975 to 2024.

Recommended Fashion Seasons

Since the temperature fluctuations between seasons are relatively small in Okinawa, choosing what to wear requires a bit of special consideration. Short-sleeved shirts and dresses can be worn for a long time, and light outerwear comes in handy in the spring and fall. From February through April and October through December, what you wear will vary depending on the time of day, the weather, and the wind, so it’s a good idea to have a few different outfits ready.

Next, check out these guidelines for dressing according to the temperature so you can enjoy a comfortable trip!

Month-by-Month Climate and What to Wear

Okinawa in January

The time when the Kanhi cherry blossoms—the earliest to bloom in Japan—begin to bloom.

This outfit might be a good choice.

Even though Okinawa is warm in winter, you’ll generally want to wear winter clothes. It gets cold because the wind is strong. It feels warm when the sun is out, and there are even a few hot days here and there. Stick to winter clothes, but if it looks like it might get hot, be sure to pack some lightweight clothing.

Okinawa in February

The coldest time of the year. It's cloudy.

This outfit might be a good choice.

Just like in January, winter attire is the norm. Knitwear and thick layers are a safe bet. Since it can get windy at times, having a coat is a good idea when you’re outside. I recommend layering so you can easily adjust your body temperature. Personally, I’m looking forward to the professional baseball spring training camps.

This outfit might be a good choice.

September in Okinawa is still “summer.” While the heat continues, there are also days with rain and strong winds. Light summer clothing is fine, but it’s handy to have a water-repellent jacket or a towel on hand in case of sudden weather changes, such as a sudden downpour.

This outfit might be a good choice.

October in Okinawa often feels like summer. However, due to the wind, some days can feel a bit chilly. While you can wear short sleeves during the day, it can get cool in the mornings and evenings. You’ll be more comfortable at night if you bring a light jacket. Many beaches close for the season by the end of October.

Okinawa in November

It’s that time of year when autumn is in full swing in Okinawa.

This outfit might be a good choice.

During the day, it’s comfortable enough to wear just a short-sleeved or long-sleeved shirt, but when the wind picks up, it can feel a bit chilly. A thick long-sleeved T-shirt, a light sweater, or a lightweight jacket will keep you just right. Some of my friends even go out in short sleeves and shorts.

This outfit might be a good choice.

The "winter" in Okinawa has a milder climate than on the mainland. You won't need a jacket during the day. On some days, even short sleeves are fine. It gets chilly in the mornings and evenings, so it's a good idea to bring a light coat or jacket.

Number of Typhoons Approaching Okinawa Over the Past 5 Years

"Number of Approaches" refers to the number of typhoons that approached Okinawa Prefecture. "Number of Formations" refers to the number of typhoons that actually formed. The "Average" is the average for the five-year period from 2020 to 2024. Looking at the data, we can say that July through September has recently been the period when typhoons are most likely to approach Okinawa.

Swimming at Okinawa's Beaches! Check When the Beach Season Opens

Beaches throughout Okinawa Prefecture officially open for the season in March or April, and visitors can enjoy swimming there until around the end of October.

In March and October, the seawater is often too cold for swimming due to the weather. The best time to enjoy swimming in the ocean is definitely from May through September.

We've compiled all the information on beach openings in a special feature.
