Climate and monthly weather forecast
The climate of Kushiro
This city, resting in the easternmost region of Japan's Hokkaidō island, greets residents and visitors alike with a Dfb Köppen climate classification, known as a humid continental climate featuring neither dry season nor particularly hot summers. This designation implies chilly winters, humid, warm summers, and considerable variability among temperatures, precipitation, and other atmospheric factors.
Analyzing the fluctuating weather throughout the calendar year, it becomes clear that the steady increase and decrease in monthly temperatures, from as low as -8.4°C (16.9°F) in February to as high as 22.8°C (73°F) in August, are attributable to the city's geographical positioning and oceanic influence. Rainfall illustrates a similar pattern, markedly increasing from 15mm (0.59") in January to a peak of 109mm (4.29") in August before tapering off by year end. There's a consistency of humidity in Kushiro throughout the year, ranging just from 76% to 88%.
Notably, Kushiro experiences significant snowfall from December to February, reaching as high as 77mm (3.03") in February. This implies the presence of substantial winter weather conditions, which are not as commonly seen in other climates of similar classification such as the Dfb.
