: 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.

are hot and humid; there can be periods of good weather, with maximum temperatures around 35 °C (95 °F), tropical nights and high humidity, but also periods of bad weather due to the summer monsoon. August is the hottest month, both because of the thermal inertia of the sea and because of the lower frequency of periods of bad weather.
