Osaka in December

A dry winter with mostly clear days. The sun sets early, so evening plans can start early. Many restaurants close around the New Year, so confirm opening hours for places you want to visit.

December in Osaka was brisk: 12°C by day, 5°C at night. Standing in the shade felt chilly. With about 6 rain days, showers were an occasional nuisance rather than the rule. Individual years ran between 1 and 11 rain days.

Days were short. Daylight shrank from 10.0 to 9.9 hours across the month, so plan outdoor sights early. About 16 nights a month dipped under 5°C, cold enough to want a jacket for the walk back. The coldest night came in 2020, at −0.6°C.

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