Spring (March–May) brings a gradual warming, turning into a warm and pleasant summer (June–August), when average temperatures rise to +20°C and above. August is the warmest month, as well as the month with the highest precipitation and number of rainy days. Autumn (September–November) is characterized by a gradual decrease in temperature, painting nature in vibrant colors before the onset of winter. Overall, precipitation is distributed throughout the year, but the total amount is moderate.

The coldest month is January, with an average air temperature of -5.1°C; during this period, minimum night values can drop to -8.4°C, and daytime maximums rarely exceed -1.9°C. In contrast, August is the warmest month, with an average temperature of +21.6°C, and daytime highs reaching an average of +24.3°C, creating comfortable conditions for summer activities.

July becomes noticeably warmer with an average temperature of +20.7°C, with daytime maximums reaching +23.5°C and night minimums around +17.9°C. The peak of summer heat occurs in August, when the average temperature is +21.6°C, with daytime values up to +24.3°C and nighttime values around +19.0°C. Daily temperature fluctuations in summer are usually 5-6°C, providing a comfortable transition from daytime heat to evening coolness.

Winter in Chitose, lasting from December to February, is frosty and snowy. December brings the first significant cold with an average temperature of -2.2°C (ranging from -4.7°C to +0.4°C). January and February are the harshest winter months with average temperatures of -5.1°C and -4.5°C respectively. At night, the thermometer regularly drops to -8°C and below (for example, -8.4°C in January), and daytime maximums often remain negative, hovering around -1°C to -2°C. Transitional months such as March (average +0.9°C) and November (average +5.2°C) show a gradual change in temperature regimes. The difference between daytime and nighttime temperatures in winter is also about 5-7°C, meaning consistently cold weather throughout the day.

Precipitation in Chitose occurs throughout the year, but its distribution has specific features. It is important to note that while the number of days with precipitation per month remains relatively constant, ranging from 11 (in March) to 16 (in August and December), the intensity of this precipitation—its total monthly amount—varies significantly. For example, during the winter months, such as January, February, and March, as well as in December, only about 2 mm of precipitation falls per month, while in August this figure reaches 6 mm. There is no pronounced heavy rainy season here, but when planning a trip, it is worth considering these seasonal fluctuations in moisture levels.

The winter months, from December to March, are characterized by snowfall. Despite the minimal total precipitation (about 2 mm per month in January, February, March, and December), snow falls quite often: there are about 16 days with precipitation in December, 12 days each in January and February, and 11 days in March. Given the average temperatures are well below freezing (for example, -5.1°C in January), this is predominantly snow. March, with an average temperature of about +0.9°C, can bring both snow and the first rains, marking the transition to spring.

From April to November, precipitation falls mainly as rain. The amount of precipitation gradually increases towards summer, peaking in August at about 6 mm. This month is also one of the "wettest" in terms of days with precipitation, with approximately 16. In other warm months, such as June and July (4 mm of precipitation and 13 days each), May (3 mm and 13 days), and September and October (4 mm with 13 and 14 days respectively), rain is also regular. The nature of this precipitation can vary from brief summer showers to more prolonged periods of overcast weather, especially in autumn.

Thus, the "driest" months in terms of total precipitation are the winter months—January, February, March, and December (all at 2 mm)—though snow falls regularly during this time. The highest amount of precipitation falls in August (6 mm), which also leads in the number of days with precipitation. Overall, travelers to Chitose should be prepared for the possibility of precipitation in any season, though its character will differ significantly: light snow in winter and rain of varying intensity during the warmer months.

When planning a trip to Chitose, it is important to choose the right wardrobe, considering the distinct change of seasons and local climate characteristics. In winter (December–February), it is quite cold here, average temperatures drop below freezing, and it often snows. Therefore, be sure to bring warm, layered clothing: thermal underwear, fleece tops, sweaters, as well as windproof and waterproof outerwear (a down jacket or a warm parka). Don't forget a hat, scarf, gloves, and warm, non-slip footwear. In spring (March–May), the weather gradually improves, but it can still be chilly, especially in March. It is recommended to dress in layers: a light jacket or windbreaker, a sweater, comfortable trousers, and closed-toe shoes. An umbrella or a light raincoat will also come in handy, as rain is not uncommon this time of year.

Summer in Chitose (June–August) is warm, and August is the warmest and most humid month. You will need light, breathable clothing made of natural fabrics: T-shirts, shorts, dresses, and sandals. However, since August is also the month with the highest precipitation and number of rainy days, don't forget an umbrella or a light raincoat. Sunscreen and a hat will also be useful. In autumn (September–November), temperatures gradually decrease. It can still be quite warm in September, but by November, the approach of winter is palpable. Layered clothing is the ideal choice: sweaters, cardigans, jeans, and a medium-weight jacket. The number of rainy days remains significant, so waterproof shoes and an umbrella are recommended.

Regardless of the season, comfortable walking shoes are always useful for exploring Chitose and its surroundings. Given that precipitation is possible year-round (from 11 to 16 days with precipitation per month), a compact umbrella or a light waterproof jacket will be your reliable companions. The principle of layering is an excellent strategy for Chitose, as it allows you to easily adapt to weather changes throughout the day.
