[2026 Latest] Okinawa's "Urizun" is here! Local editors share tips on how to enjoy the season comfortably and what to wear.

Here I am! It's Ima-chan from the Okinawa editorial team! Today in Okinawa, the weather is absolutely perfect, just like the typical "Urizun" season. Relaxing in the park, I'm enjoying the clear blue sky and the pleasant sound of birdsong.

The humid, oppressive temperatures of yesterday seem like a distant memory... The wind is calm, making today a perfect day for stand-up paddleboarding (SUP). If you're about to land at Naha Airport by plane, you're probably seeing the breathtaking scenery from your window that's exactly what you imagined Okinawa to be like!

However, having lived in Okinawa for several years, I have several tips to share to help you avoid making mistakes when sightseeing there during this time of year. I've compiled some tips for enjoying Okinawa comfortably and smartly.

1. What kind of season is "Urizun"? In the Okinawan dialect, the fresh season of early summer, around the second to third month of the lunar calendar (March to April in the Gregorian calendar), when young leaves sprout and the earth begins to become moist, is called **"Urizun"**. It is the most comfortable season of the year, not too hot and not too cold, truly a "heavenly season." Today's conditions Sky: Clear skies with not a cloud Wind: Gentle (perfect for marine activities) Humidity: Low and dry Sea: Calm waves, perfect for SUP and kayaking During this time of year, you can simply sit on the grass in the park and do nothing, and it's a special time when you can truly refresh your mind.

2. [Caution] The "gap" between the daytime heat and the nighttime chill During the "Urizun" season, the temperature rises enough during the day to wear short sleeves. If you're out in the sun, you might feel like it's already summer! However, you shouldn't let your guard down because of the chill at night. Temperature difference due to radiative cooling Especially on sunny, cloudless days like today, "radiative cooling" occurs at night as heat escapes from the ground. Daytime: Around 25℃ (warm enough to make you sweat) Nighttime: Can drop below 20℃ (surprisingly chilly) What I've learned firsthand from living here for the past few years is that **"Okinawa nights are surprisingly cold"**. The perceived temperature drops significantly, especially along the coast and in windy areas.

Recommended clothing

3. Preparing for "Katabui," a unique weather phenomenon in Okinawa. The skies of Okinawa are very unpredictable. One moment it's perfectly clear, and the sky suddenly turns cloudy, and you're hit by heavy rain. This is called **"Katabui"** in the Okinawan dialect. Why is a "sun and rain umbrella" essential? Katabui is a localized rain, so it usually stops within a few minutes to a few tens of minutes, but the rain is quite heavy. As a parasol: Protects your skin and energy from the deadly direct sunlight (if you get a headache, that's bad! Remember to stay hydrated). As a rain umbrella: To withstand sudden katabui. You might think, "It's a hassle to carry an umbrella around...", but in Okinawa, having just one sun and rain umbrella can dramatically reduce your energy expenditure.

4. Eye pain is a sign of sunburn! A blind spot in UV protection With the sun shining so brightly, the one thing you need to be careful of is your eyes. In fact, Okinawa's strong UV rays can cause significant damage not only to your skin but also to your eyes. Three essential items when walking outside: Hat: A wide brim is best. It also protects your scalp from sunburn. Sunglasses: UV rays entering the eyes can cause fatigue. Umbrella for both sun and rain: As mentioned above, the strongest defense item. If you feel your eyes are hurting, it's a sign that you've already been exposed to a lot of UV rays. Especially when staying in places with no shade for a long time, such as beaches or parks, be sure to actively make efforts to create shade.

5. Today's Activity: SUP Recommendation Today's calm winds make it a perfect day for SUP! On days when the water is as calm as a mirror, you can sometimes see coral and fish underwater from your board. Safe for Beginners The calm seas of Urizun are perfect for your first SUP experience. Location: Calm beaches in Onna Village, Chatan, and the southern part of Okinawa. What to Bring: Rash guard (for sun protection), drinks, and a change of clothes for afterward. Just balancing on a buoyant board will strengthen your core muscles and detoxify your mind and body.

Summary: Enjoy the best of Okinawa "smartly"! Today's weather in Okinawa is like the "best gift" for visitors. Be sure to enjoy the tropical atmosphere the moment you step off the plane, and the refreshing breeze unique to Urizun with all your senses. Summary of advice from Ima-chan Bring a light jacket to prepare for the temperature difference at night. Use a parasol that can be used for both sun and rain to deal with both "katabui" (sunny breeze) and "direct sunlight". Protect your eyes with a hat and sunglasses. Show respect to nature, be fully prepared, and enjoy a wonderful trip to Okinawa! This has been Ima-chan from the Okinawa editorial department! Editor's note I hope this article will serve as a travel guide for those who will be visiting Okinawa in the future. I hope that even if you encounter "katabui," you will be able to laugh it off and say, "Oh, so this is what they've been talking about!" and have a relaxed trip. See you in Okinawa!
