[2026 Update] March in Okinawa is surprisingly cold! Real-world clothing tips and things to watch out for, as told by a local writer.

Hi there! This is the ima.okinawa editorial team. March has arrived in 2026, and news of beaches opening for the season is starting to be broadcast throughout Okinawa. It's an exciting time of year, with everyone thinking, "Summer is finally here!" However, the most common mistake people make when traveling to Okinawa at this time of year is choosing the right clothes. We often see people arriving at the airport thinking, "It's a tropical country, so a T-shirt should be fine," only to be surprised by the cold and rush to Uniqlo on Kokusai Street... This time, along with a look at the current weather in Okinawa, we'll share some tips for comfortably enjoying March in Okinawa.

1. [True Story] The "Mountain Chill" I Witnessed on a Delivery Job on a March Night Today, I was driving around in the mountainous areas of Nakagusuku Village and other places for a delivery job from the evening. During the day, the sun was shining, and there were moments when I felt a slight, scorching "Okinawan heat," but after 6 PM the air changed completely. In the mountainous areas of Nakagusuku, along with a light drizzle, a chill that seemed to penetrate to the bone began to spread. My Outfit Today (Mistake and Recovery) At Departure: Underwear top and bottom, thin summer pants and a light dress shirt. The moment I stepped outside: I instinctively thought, "Oh, this is bad." Countermeasure: I immediately put on the **"water-repellent jacket"** that I had in my car to regulate my body temperature. It was still before 8 PM, but at this point I was certain that "it's going to get even colder tonight." In fact, when I got home I couldn't help but turn on the heater.

2. Why is it cold in Okinawa in March, even though the temperature is 20°C? Looking at the weather forecast, the maximum temperature in Okinawa in March is 20°C to 23°C. Looking at the numbers alone, it seems like "spring weather," but Okinawa has a formidable enemy: **"winds from the north."** For every 1 meter per second of wind speed, the perceived temperature drops by 1°C. Okinawa has a mostly flat terrain, allowing winds from the sea to blow directly through. Especially when it's cloudy and winds blow from the north, the perceived temperature can drop sharply below 15°C. The "scorching heat" on sunny days and the "extreme cold" when the wind blows—this drastic gap is the true nature of March in Okinawa. This is the time of year when even locals are most susceptible to catching a cold. We locals are especially careful about the cold at night.

3. [2026 Edition] Clothing Advice for Those Coming to Okinawa: For those of you planning a trip to Okinawa, please don't forget the following "three essential items" when packing.

① Hooded sweaters or hoodies: You might think, "Sweaters in Okinawa?", but don't underestimate the chill at night. I especially recommend hooded sweaters. The Okinawan wind chills your ears. On windy nights, simply wearing a hood makes a dramatic difference in how warm you feel.

② Water-repellent jacket March in Okinawa is called "Ningachi Kajimaya" (February wind shift), and the weather is very unstable. It can be sunny one moment and then suddenly start to drizzle the next. A water-repellent jacket or mountain parka that can also be used as a raincoat will prevent you from losing body heat even in sudden rain.
​
③ Adjusting with innerwear: During the day, short sleeves or light shirts are fine, but it's reassuring to wear a functional inner layer underneath.

4. Enjoying the Evolving Okinawa in 2026 Currently, Okinawa is experiencing many new changes, such as the excitement surrounding the new theme park "JUNGLIA" in the northern area and the progress of the reconstruction of Shuri Castle's main hall. While the area is bustling with activity, extra caution is needed when driving rental cars or in unfamiliar territory. In particular, Okinawa's roads can be slippery after rain, so please drive safely.

Summary: For a pleasant trip, March in Okinawa is a unique season where spring and winter coexist. During the day, prepare for "summer" (sunscreen) and at night, prepare for "winter" (a warm jacket). The key to enjoying your Okinawa trip is to be fully prepared. Please come fully equipped so you don't catch a cold from the night chill. ima.okinawa sincerely hopes that your trip will be safe and create wonderful memories. Have a great trip!
