Winters here are quite cold, with average temperatures hovering around zero degrees Celsius in January and December, accompanied by a high number of days with precipitation.

Spring (March–May) and autumn (September–November) in Shirayama are pleasant transition periods with moderate temperatures. Spring brings gradual warming, while autumn sees a steady cooling. Precipitation during these seasons is moderate, but the number of "wet days" remains quite high, indicating frequent but not always heavy rainfall.

One of the notable features of the weather in Shirayama is the high frequency of days with precipitation throughout the year, even when monthly totals are relatively low. This is particularly evident in the winter months (January, December) and during the height of summer (July, August). This suggests that the sky is often overcast, with frequent light rain or drizzle. July stands out as the month with the highest rainfall volume (11 mm) while also being one of the months with a very high number of rainy days (22 days), although January and December exceed it in this regard (with 26 "wet" days each).

The climate in Shirayama is characterized by distinct seasonal temperature changes. A significant range of temperatures is observed throughout the year. The hottest month is August, when the average temperature is 25.9°C, and daily highs reach an average of 28.6°C. In contrast, the coldest month is January, with an average temperature of only 1.7°C and average nightly minimums dropping to -1.1°C.

The summer period in Shirayama, covering June, July, and August, brings warm and sometimes hot weather. June begins with an average temperature of 20.1°C, which gradually rises to 24.5°C in July and reaches its peak in August. Daytime temperatures in the height of summer can be quite high, creating a sultry feel, especially since nights also remain warm (August average minimum is 23.2°C). Transitional months like May (average temperature 16.2°C) and September (22.3°C) offer more moderate and pleasant warmth.

Significant fluctuations between daytime and nighttime temperatures are observed throughout the year, especially in the spring and autumn months, where the difference between average maximums and minimums can reach 6-7°C, which is worth considering when planning evening activities.

Precipitation is a frequent occurrence in Shirayama throughout the year. While there is no pronounced dry season where rain is completely absent, there are noticeable fluctuations in both the amount of precipitation and the number of rainy or snowy days.

The winter months, particularly January and December, are characterized by the highest number of days with precipitation—averaging 26 days each. Given the low average monthly temperatures (1.7°C in January and 4.2°C in December, with minimums dropping below freezing in January), precipitation during this period, as well as in February (18 days with precipitation), often falls as snow or mixed precipitation. The total precipitation in January is 7 mm, and in December it is 8 mm. Notably, February (with 18 days of precipitation) and March (with 16 days) are the months with the lowest precipitation volume—only 5 mm each—even though February's precipitation can still be snowy.

In spring, the number of days with precipitation decreases. April and May are the months with the fewest wet days in the year (13 days each) and relatively low precipitation—6 mm each. This period can be considered relatively drier in terms of frequency. Conversely, summer brings more moisture. July stands out as the wettest month by volume, reaching 11 mm, with 22 rainy days. August is also quite wet, with 8 mm of precipitation and 20 rainy days, indicating a summer peak likely in the form of heavy rain.

The autumn months—September (7 mm of precipitation, 18 wet days), October (6 mm, 16 days), and November (6 mm, 17 days)—show moderate precipitation and an average number of wet days. Overall, when planning a trip to Shirayama, you should be prepared for precipitation at any time of year, though its character and intensity will change depending on the season: from frequent but not always heavy snowfalls in winter to more intense rains in mid-summer.

When planning a trip to Shirayama, it is important to consider the distinct seasonal changes and frequent precipitation. In winter (December to February), it is quite cold, with average temperatures ranging from 1.7°C to 4.2°C, and nighttime temperatures can drop below freezing. Therefore, your suitcase should definitely include a warm winter jacket or coat, sweaters, thermal clothing, a hat, gloves, and a scarf. Given the high number of days with precipitation (especially in January and December), waterproof shoes and outerwear will be very useful. Don't forget an umbrella—it will be handy any time of year.

Spring (March–May) and autumn (September–November) in Shirayama are characterized by milder weather. Temperatures gradually rise in spring (from 6.7°C in March to 16.2°C in May) and decrease in autumn (from 22.3°C in September to 10.5°C in November). During these periods, layering is the ideal approach: a light jacket or windbreaker, jumpers, and t-shirts. The number of rainy days remains significant, so a compact umbrella or a light raincoat is still essential. In summer (June–August), Shirayama is warm, with average temperatures reaching 20.1°C - 25.9°C. Pack light, breathable clothing made from natural fabrics. However, July and August also see high precipitation and many wet days, so a light raincoat or umbrella is recommended. Sunscreen and a hat will also come in useful on clear summer days.

Regardless of the season, comfortable walking shoes are an absolute necessity, as you will likely want to explore the surrounding areas. Given the frequent precipitation throughout the year, choose shoes that dry quickly or are waterproof. A power adapter and a portable charger may also be useful companions for your journey through Japan.
