Can You Swim in the Sea in Okinawa in October?

Yes, you can. Actually, October is the last chance to enjoy warm sea waters in Okinawa, with the average temperatures about 27 degrees Celsius (81 degrees Fahrenheit). After this month, the ocean becomes chilly, so we highly recommend that you make the most of beach time during this period.

However, it’s best to avoid entering the water during the early morning and late afternoon, as you would feel chilly, especially after getting ashore in wet. Plus, preparing a big towel and a light jacket to keep warm is a good idea.

Travel Highlights and Tips

1. Naha Tug-of-War Festival

Around mid-October in 2025, Okinawa’s capital comes alive with the Naha Tug-of-War Festival, one of the island’s most iconic cultural events. The highlight of the festival is the massive tug-of-war itself, where two opposing teams, dressed in traditional Ryukyuan costumes, battle against each other by dragging a rope that stretches over 100 meters (328 inches) in length. The point is that visitors can actually also join the action and are allowed to keep pieces of the rope as a lucky item.

Besides, colorful parades, traditional performances, and lively street celebrations fill the city, making you fully immerse in local cultural charm.

Tip: Don’t forget to ensure the specific date on the official website in advance.

2. Onna Village Tour

It’s highly recommended to spend your day in Onna Village discovering the charm of Okinawa. For water activity lovers, diving into the Blue Cave is an unforgettable experience: the sunlight filters through the sea, illuminating vibrant coral reefs and colorful tropical fish. If diving isn’t your thing, nearby sights like the dramatic cliffs of Cape Manzamo offer equally wonderful views of the coastline.

On the evening of October 12th, Onna Village lights up with its annual Fireworks Festival. Expect more than just fireworks: traditional Eisa dance performances and live music create a lively atmosphere that celebrates Okinawa’s culture under the night sky.

Tip: Book a beachfront hotel with a sea-facing balcony. That way, you can catch a spectacular sunset or even watch the fireworks without leaving your room.
