: in winter, the northwest cold currents prevail, while in summer, they are replaced by hot and humid currents of tropical origin.
The city is located at a low latitude (at the 33rd parallel), but close enough to the Asian continent to receive cold air masses in winter, which are able to lower the temperature to some extent.
, the sky is often cloudy, as is common on the Japanese western side. There are fairly mild periods, with highs above 10 °C (50 °F), but also cold periods, with wind and rain, highs around 5/7 °C (41/45 °F) or less, and possible falls of sleet or snow.
