Map from Google - Shizuoka

In Shizuoka the climate is temperate, with mild and sunny winters, and hot, humid and rainy summers. Like the rest of Japan, the city is affected by the monsoon circulation: in winter the northwest cold currents will prevail, while in summer they will be replaced by the hot and humid currents of tropical origin.
Shizuoka is located in the central part of Honshu, halfway between Nagoya and Tokyo, and on the coast, in Suruga Bay, an area particularly exposed to the summer monsoon. North of the city lie the Akaishi Mountains (or Southern Alps, with a series of peaks around 3,000 metres (9,800 ft) high and some winter resorts), while to the north-east is Mount Fuji.
Given the relatively low latitude (we are on the 35th parallel), and the protection of the mountains (we are on the southern side), in winter the currents of Siberian origin are felt little, so there are several sunny days, and usually it's not very cold; however, cold and windy periods, with highs around 7/10 °C (45/50 °F) or less, can not be ruled out. Snowfall is very rare: unlike in Tokyo, where sometimes it can snow, here in practice it never snows. Night frosts are rare and usually light.
Although it rarely rains in winter, given the exposure to southern winds, when it rains, it can rain a lot.
In summer, hot and muggy periods alternate with periods of bad weather, with wind and rain.
Here are the average temperatures.

In Shizuoka precipitation is abundant: even 2,300 millimetres (90 inches) per year, which make it one of the rainiest cities in Japan (along with some cities in the northern side of the island of Honshu, as Kanazawa and Komatsu). The driest season is definitely the winter; in summer, from June to September, more than 1,100 millimetres (43 inches) of rain fall.

In late summer and early autumn, from August to October, Shizuoka can be affected by typhoons, tropical cyclones, which in this area, facing south, are felt in a particular way. The most intense typhoons can bring torrential rains and heavy damage.
The cherry blossoming in Shizuoka takes place around the 30th of March.
The amount of sunshine in Shizuoka is good in winter (there are more than 6 hours of sunshine per day in December and January), while it is just mediocre or decent in the other seasons, due to spring and fall disturbances and to the summer monsoon.
