Yokohama overlooks the sea in Tokyo Bay, not far from the Japanese capital, and is located on the island of Honshu, in the Kanto region.
Given the relatively low latitude (we are on the 35th parallel), and the protection of the mountains (we are on the east side), in

, hot and muggy periods, with highs around 35 °C (95 °F) and high humidity, alternate with periods of bad weather, with wind and rain, and sometimes (especially in June and July) temperatures a bit cool at night. 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.
is abundant, in fact, it amounts to 1,700 millimeters (67 inches) per year. Winter is undoubtedly the driest season; the rainiest months are September and October, also because of the contribution given by typhoons. In August, there is a certain decrease in rain frequency: on average, among the summer months, it is the driest and sunniest as well as the hottest.
in Yokohama is good in winter (there are no less than 6 hours of sunshine per day in December and January), while it is just mediocre or decent in the other seasons because of the weather disturbances that pass in spring and autumn, as well as of the summer monsoon. However, among those of summer, August is the sunniest month.

As mentioned, from June to October (but especially from August to early October), Yokohama can be affected by
, the tropical cyclones of South-East Asia, which mostly affect the southern part of the country but can also arrive here. The most intense typhoons can bring strong winds, torrential rains and heavy damage.
From the climatic point of view, the best times to visit Yokohama are spring and autumn, and in particular, from mid-April to mid-May and from late October to mid-November.
(Sakura) in Yokohama reaches its peak around March 30. About a week passes between the beginning and the peak of the flowering. The blooming date can vary by a few days, or even a week, earlier or later, depending on the year. There are dedicated events in the streets and parks where you can admire them. Although in some years it can get a little cold, with highs around 10/12 °C (50/54 °F), you can also take advantage of this period.
