Summers in Susono, particularly in July and August, are quite warm and humid, with average temperatures reaching 24-25°C and highs of up to 28°C. This period also sees the highest amount of rainfall and rainy days, especially from June through September.

Spring and autumn are transitional seasons with pleasant, mild weather, featuring a gradual warming in spring and cooling in autumn.

The most notable feature of Susono's climate is the pronounced wet season during the summer months, when the number of rainy days reaches 20-21 per month, and rainfall volume increases to 8-10 mm. The winter months, December and January, are the driest, with minimal precipitation (around 2 mm) and fewer rainy days. This creates a contrast between the humid, warm summers and the drier, cooler winters.

The city of Susono experiences a distinct change of seasons with notable temperature fluctuations throughout the year. The hottest month is typically August, when the average temperature reaches 25.3°C and highs can rise to 28.1°C. The coldest month is traditionally January, with an average temperature of about 4.2°C and nightly lows averaging 0.9°C. Thus, the annual temperature cycle shows a transition from a cool winter to a warm and occasionally humid summer.

Summer months in Susono, particularly July and August, are characterized by warm and sometimes hot weather. Average daily temperatures during this period stay consistently above 20°C (June – 19.9°C, July – 24.1°C, August – 25.3°C). Daytime highs regularly reach marks from 23°C in June to 28°C and above in August. Nights also remain warm, with minimum temperatures rarely falling below 16-22°C. The difference between day and night temperatures in summer narrows slightly to an average of 5-6°C, often due to the high humidity typical of Japanese summers.

Winter in Susono is quite cool but not harsh. From December to February, average temperatures range from 4.2°C to 6.4°C. At night, the thermometer can drop close to zero, especially in January (average minimum 0.9°C), but severe frosts are not common. During the day, temperatures usually rise to 7-10°C. The transitional seasons—spring and autumn—are marked by gradual temperature changes. March and April bring noticeable warming, while October and November see a steady cooling. Diurnal temperature fluctuations during these periods can be slightly more pronounced than in summer, reaching 7-8°C, which creates pleasant conditions for walking and exploring the city.

The city of Susono experiences pronounced seasonality in precipitation distribution throughout the year. The highest rainfall occurs during the summer months. June and July are the wettest, with monthly rainfall levels around 10 mm and approximately 20 rainy days. August and September are also characterized by significant precipitation (8 mm) and a high frequency of rainy days (21 and 20 days, respectively). This indicates a summer rainy season.

The driest months in Susono are December and January, with only about 2 mm of precipitation and the number of rainy days dropping to 10-11. February and November are also relatively dry, with 4 mm of precipitation. The spring months (March, April, May) and October represent a transitional period with moderate rainfall ranging from 7 to 8 mm and 15-17 rainy days.

Considering the average monthly temperatures, especially in winter (January min: 0.9°C, December min: 2.9°C), snowfall is possible; however, the low precipitation during these periods (2 mm) suggests that heavy snowfall is unlikely. Throughout the rest of the year, precipitation mostly falls as rain. In summer, despite having the highest rainfall, it likely takes the form of periodic showers, given the high temperatures and the number of wet days.

When planning a trip to Susono, it's important to consider the variable weather typical of this region of Japan. Regardless of the season, layering is key. This will allow you to easily adapt to temperature changes throughout the day. Be sure to bring comfortable walking shoes, as you'll likely want to explore the surroundings. Given the frequent rainfall throughout the year, a compact umbrella or a light waterproof jacket will be indispensable companions.

If your trip falls during the winter months (December to February), be prepared for cool weather with average temperatures ranging from 4°C to 6°C, and occasionally lower. You'll need a warm jacket, sweaters, a hat, gloves, and a scarf. In spring (March to May) and autumn (September to November), the weather is milder but still changeable. A mid-season jacket and warm sweaters are useful in early spring and late autumn, while lighter options suffice in May and September—though you should always have something on hand for a sudden chill or rain.

The summer months, from June to August, are warm in Susono, with average temperatures between 20°C and 25°C. During this time, you'll need light and breathable clothing: t-shirts, shorts, light trousers, or dresses. Don't forget sunscreen, a hat, and sunglasses for sun protection. June, July, and August also see the highest rainfall and humidity, so a light raincoat or umbrella remains essential. Overall, being prepared for changeable weather and rain will make your stay in Susono as comfortable as possible.
