Climate chart - Kanazawa (Japan)
In Kanazawa, a city of Japan, located on the west side of Honshu Island, the climate is humid semi-continental, with cold, damp winters and hot, moist summers. There is no dry season. Like the rest of Japan, the city is affected by the monsoon circulation: in winter, the northwest cold currents prevail, while in summer, they are replaced by hot and humid currents of tropical origin.
In winter, cold winds from the Asian continent are loaded with moisture when passing over the sea, and then hit the coast directly. In Kanazawa, the temperature is slightly above freezing (0 °C or 32 °F), the sky is cloudy, the wind blows, and it rains and snows almost every day. It snows especially in January and February; on average, more than two meters and a half (8 feet) of snow fall per year. The snow is usually wet and therefore very heavy, so the traditional houses have sloping roofs, while the trees in the botanical garden are supported with special rods. Waves of intense cold are rare: usually, the temperature does not drop below -5 °C (23 °F), although the cold is fairly constant and the air is humid.
The presence of maritime air in the city makes great snowfalls rare, in fact, even if it snows a lot, the snow tends to melt. On the contrary, in inland areas, already at low altitude, but especially on the slopes of the mountains exposed to the northwest, very heavy snowfalls occur, and meters of snow accumulate. It is no coincidence that this region of Japan is called "snow country" or Yukiguni (and in the mountains, there are several ski lifts).
In summer, periods of fine weather, hot and humid, alternate with periods of bad weather, with wind and rain. August is the warmest month, both because of the thermal inertia of the sea and because of the lower frequency of periods of bad weather.
Here are the average temperatures.

In Kanazawa, precipitation is definitely abundant, and amounts to 2,400 millimeters (94.5 inches) per year, which make it one of the rainiest cities in Japan (together with some cities on the southern side of the island of Honshu such as Shizuoka and Owase) and one of the extratropical rainiest cities in the world (together with Valdivia, Chile). Precipitation is more frequent in winter but more intense in summer. The (relatively) driest season is spring; in summer, when the monsoon is somewhat less intense than in southern Japan, there is a certain drop in rainfall in August. Here is the average precipitation.

From June to October (but especially from August to early October), Kanazawa can be affected by typhoons, though usually with lower intensity than in southern Japan.
Best Time
From the climatic point of view, the best times to visit Kanazawa are spring and autumn, and in particular from late April to late May and from mid-October to early November.
The cherry blossoming in Kanazawa occurs around April 7-8, with a variability of about one week before or after depending on the year: even though in some years it can get a little cold, with highs around 9/10 °C (48/50 °F), you can also take advantage of this period. On the other hand, from late October to mid-November, you can admire the autumn leaves in the famous Kenrokuen Garden (which is considered as one of the three most important, together with the Kairakuen in Mito and the Korakuen in Okayama) or around temples.
In summer, August is partly preferable to July, having more sunshine and less rainfall, but it is also true that it is hotter and there's a greater risk of typhoons.
