Amami Island


Amami Oshima Island has that laid-back subtropical feel, like the weather’s always in holiday mode. The yearly temperature hangs around 21°C (70°F), so it's never too hot or too cold. But when it rains, it pours – with more than 3,000 millimeters (about 118 inches) of rain every year! Don't forget to keep an eye out for typhoons from June to September, as they can bring strong winds and heavy rain. That’s why everything is so green and lively.




The weather varies widely. Wear light long sleeves that you can easily remove. Mornings and evenings can feel a bit chilly. In April and May, it warms up, and you'll probably be comfortable in short sleeves most days. Don't forget to bring rain gear as well.

June and early July are hot but they can be cloudy and rainy. July and August are the best months to enjoy marine sports to the fullest. The sun is strong so be sure to bring sunscreen. Be aware that typhoons are more likely during this time.

The season can feel quite cold because of strong North winds. Although it can be warm when you're active, mornings and evenings are cooler, so layer with lightweight clothing underneath and wear a parka, coat, or warm outerwear.
