Naha in April

Many people name it the best month for swimming. The sea has warmed a lot, and the heavier early-summer rains have not yet arrived. Golden Week begins late in the month, and flights and rooms jump in price.

Afternoons reached 25°C and nights settled at 19°C, warm enough to linger over lunch outdoors. With 10 rain days on average, a wet day was rarely more than a few days away. Averages hide a lot here: one year saw 3, another 15.

Each rainy day brought about 18 mm, closer to downpours than drizzle.

Typhoons i No tropical storm passed within 300 km in this month over the last 20 years. Typhoons: May to October
