Naha in December

Fewer tourists and mild weather make this a fine winter escape. Whale-watching season usually starts in January, so December is still early. Plan around the city and castle sites rather than the beach.

Highs averaged 22°C and lows 17°C, an easy range for walking around all day. Day and night differed by only 5°C, so one outfit worked from breakfast to late dinner. Rain fell on 10 days of the month on average. Averages hide a lot here: one year saw 4, another 24.

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