The best time to visit Okinoerabujima is during the spring (late March to May) and autumn (October to November) months.
Spring offers pleasant temperatures, typically ranging from 18°C to 25°C, making it ideal for outdoor activities like exploring the island's many caves, such as Shoryu-do, or enjoying the beaches. The island is also particularly beautiful in spring when various flowers, including lilies, are in bloom. It's a great time for couples seeking a relaxed and scenic getaway, with comfortable weather for leisurely walks and enjoying nature.
Autumn provides similarly comfortable weather, with temperatures between 20°C and 27°C, and generally less rainfall than the summer months. This season is superb for diving and snorkelling, as the water remains warm and visibility is usually excellent. Families often find autumn a good time to visit, as the cooler temperatures are more suitable for children to enjoy outdoor adventures without the intense heat and humidity of summer.
While summer (June to September) is warm, with temperatures often exceeding 30°C and high humidity, it also brings typhoon season, which can disrupt travel plans. Winter (December to early March) is cooler, around 15°C to 20°C, and can be quite windy.
