Find out the current weather situation in the city of Wakkanai to make your journey as comfortable as possible. Below are up-to-date forecasts and detailed charts to help you plan your day wisely.

The climate of Wakkanai can be described as humid continental with tangible maritime influence. As Japan's northernmost city, it is distinguished by cool weather even at the height of summer, making it a unique destination for those wishing to avoid the sweltering heat typical of the country's central and southern regions. The change of seasons is clearly traceable here, yet the general temperature background remains moderate throughout the year.

Winter in Wakkanai is long and cold, with sub-zero average temperatures and frequent precipitation. The number of "wet" days in the winter months is very high, guaranteeing abundant snowfall and harsh landscapes. Summer here is short and very mild: even in the warmest months, July and August, the thermometer averages around 19–20°C, ensuring comfortable and refreshing conditions for travel.

A characteristic feature of the local weather is constant sea winds, which can heighten the sensation of cold. Precipitation falls regularly, but its intensity is not too high, except for winter blizzards. Tourists should note that the weather can be changeable, so even when planning a summer trip, it is recommended to carry a light jacket or windbreaker.

The temperature regime of Wakkanai is determined by its geographical position at the very north of the country, offering travellers a cool and fresh climate. The coldest period falls in January and February, when the average temperature holds at -4.7°C, and night frosts regularly reach -6.4°C. Winter takes hold early here: already in December, average readings drop below zero, creating conditions for frosty weather.

Summer in Wakkanai differs radically from the sultry season in the central part of Japan — it is mild and very comfortable here. The warmest month is August with an average temperature of about +19.9°C and daily highs rarely exceeding +21.7°C. July also brings pleasant coolness (+18.6°C), making the city an ideal refuge for those who tolerate intense heat and high humidity poorly.

An interesting feature of the local climate is the insignificant difference between day and night temperatures throughout the year, averaging just 2–4 degrees. This testifies to the strong influence of the sea, smoothing out daily fluctuations. Transitional seasons here are prolonged and cool: in spring, the air warms up to +9.7°C only by May, and in autumn, noticeable cooling arrives as early as October, when the average temperature drops to +11.8°C.

Wakkanai, being the northernmost city in Japan, is characterized by marked precipitation seasonality, strongly influenced by its geographical location. Winter here is long and snowy: from December to February, the highest number of inclement days in the year is observed (up to 24–25 days per month). Considering that the average temperature at this time stays below zero (about -4.7°C), the city is often covered in a dense layer of snow, creating picturesque but harsh winter landscapes.

In spring and the first half of summer, the weather becomes more favourable for travel. The "driest" month in terms of precipitation frequency is July, when only about 8 rainy days are recorded. This is perhaps the best time for a visit: the air temperature becomes comfortable (averaging 18.6°C), and the probability of getting caught in prolonged rain is minimal. However, already in August, the number of wet days rises again to 14.

Autumn marks a gradual transition to the winter regime: the number of days with precipitation increases, reaching 22 days in November. During this period, rains begin to give way to sleet as it gets colder. In general, Wakkanai is characterized by fairly frequent precipitation throughout most of the year, so waterproof clothing and footwear will be relevant for tourists in almost any season, with the exception of a short period in mid-summer.

When preparing for Wakkanai, the northernmost city in Japan, it is important to remember its cool climate and frequent winds. Winters here are frosty and snowy, so for a trip from December to March, you will definitely need high-quality warm clothing: thermal underwear, a windproof down jacket, a hat, a scarf, and mittens. Pay special attention to footwear — it should be warm, waterproof, and have non-slip soles, as the number of days with precipitation in the winter period is high.

Summer in Wakkanai is very mild and fresh, and there is no sweltering heat here — even in August, the average temperature holds around +20°C. Therefore, when planning a journey in the warm season, do not limit yourself to T-shirts: be sure to take a windbreaker, a fleece jacket, or a light coat. The principle of layering in clothing will be the best solution, allowing you to feel comfortable both in the cool morning and during the day.

Regardless of the season, your suitcase should contain items for protection against rain and wind. Since there are quite a few wet days in the year, especially in late autumn, a sturdy umbrella or a quality raincoat will become indispensable accessories. We also recommend taking comfortable, proven footwear for long walks along the picturesque capes and sunscreen, as even with a cool wind, ultraviolet radiation remains active.
