This indicates a pronounced period of high humidity.

The hottest month is typically August, when the average temperature is 24.8°C, and daytime highs can reach 28.0°C. Conversely, the coldest month is January, with an average temperature of just 2.3°C and average nightly lows dropping to -1.8°C. This wide annual temperature range allows visitors to enjoy all the beauty of the changing seasons in this Japanese city.

Summer in Chichibu, lasting from June to August, brings steady warmth. In July and August, average daytime temperatures consistently stay above 26°C (peaking at 28.0°C in August), while nights remain fairly warm, with temperatures rarely falling below 20°C. June is slightly cooler, with average highs around 23.1°C. Given the high number of rainy days in the summer (from 22 to 26 days per month), high humidity is to be expected, making the heat feel more intense.

Winter in Chichibu, spanning from December to February, is cool and occasionally frosty. Average nightly temperatures in January and February drop below freezing (to -1.8°C and -1.3°C respectively), while daytime highs during these months usually hover around 6.5°C – 7.9°C. December is also cold, with average lows near -0.1°C. Throughout the year, especially in the transitional seasons (spring and autumn) and winter, there are noticeable diurnal temperature variations. For example, in February, the difference between the average high (7.9°C) and low (-1.3°C) is more than 9 degrees, which is worth considering when choosing your outfit for a walk.

The city of Chichibu experiences noticeable seasonality in its precipitation distribution throughout the year. There is a distinct wet period during the summer and early autumn months, contrasted with a drier winter season. Overall, the amount of precipitation in Chichibu is modest, but the frequency of rainfall varies significantly.

The highest amount of precipitation and the most rainy days occur between May and October. July is the wettest month, averaging 10 mm of precipitation and up to 26 days with rainfall. June, August, September, and October also see relatively high precipitation (around 8 mm each month) and a large number of rainy days (from 18 in October to 25 in August). This suggests that during the summer and early autumn, precipitation—likely in the form of rain—occurs very frequently, even if the intensity remains low.

The winter months, from December to February, are the driest in Chichibu. December stands out as the month with the least precipitation—only 1 mm and about 8 rainy days. January (2 mm, 9 days) and February (3 mm, 9 days) also feature low levels of precipitation. Given that minimum temperatures in these months can drop below freezing (especially in January with a low of -1.8°C, February with -1.3°C, and December with -0.1°C), some of this sparse winter precipitation likely falls as snow.

When planning a trip to Chichibu, it is important to consider the significant seasonal weather variations. In winter (December–February), it is quite cold, with average temperatures ranging from 2.3°C to 4.3°C, and nightly frosts are a common occurrence. Therefore, your luggage should definitely include a warm jacket, sweaters, a hat, gloves, and a scarf. Although precipitation is low during this time, the cold wind can be biting. Spring (March–May) and autumn (October–November) are characterized by milder weather with gradual temperature changes, so the principle of layering will be very useful: T-shirts, long-sleeves, and light jackets or windbreakers that can be added or removed depending on the weather. Don't forget an umbrella or a raincoat, as the number of rainy days increases noticeably from March through October.

The summer months (June–September) in Chichibu are warm and humid, with average temperatures ranging from 19.4°C to 24.8°C, and daytime highs can reach 28°C. During this period, you will need light, breathable clothing made of natural fabrics, shorts, and T-shirts. Given that July and August are the rainiest months with the highest number of precipitation days (up to 26 days in July), a compact umbrella or a light raincoat will be indispensable companions. Also, remember sunscreen and a hat for protection on clear days. Comfortable walking shoes are recommended for all seasons, as Chichibu and its surroundings offer many interesting spots for hiking.

Regardless of the time of year, pay attention to the number of "wet days" in the weather summary. Even if the total precipitation in millimeters is low, frequent, albeit light, rains can catch you off guard. Therefore, a compact umbrella or a light waterproof jacket will be useful almost year-round, especially from spring to autumn. Layering will allow you to stay comfortable as temperatures fluctuate throughout the day, which is particularly relevant during the transitional seasons.
