Naha weather by month
2006-2025, 20 years of records · Not a forecast
Naha has a mild subtropical climate even in winter. The Okinawa rainy season starts in early May and ends in mid to late June, and typhoon approaches peak in August. Most beaches open from mid-March and swimming gets comfortable from April. In winter, whale watching and cherry blossoms suit better than the beach. Leave a buffer day before your flight home in case a typhoon cancels flights. A rental car makes rainy days far easier.
March, April and November gave the best mix of comfortable warmth and few rain days in Naha. To dodge the rain, July and October to April (10 rain days) was the stretch to look at, not June, August and September (13).
