Cold Weather in December

Sapporo in December experiences a truly cold climate, with the average temperatures ranging from -4-2°C (25-36°F). In fact, it is often below freezing throughout the day and the perceived temperature can be 3-4 degrees Celsius (37-39 degrees Fahrenheit) below than what’s shown in the weather forecast.

The good news is, indoor heating system is excellent across the city. Plus, there is an underground street in the city center that leads to the main scenic spots, allowing you to avoid the cold weather outdoor for some while. If you are spending your time indoors, such as shopping malls or museums, a thick sweater and wool coat will keep you warm enough. However, for extended outdoor activities like snow viewing at Odori Park, it’s best to wear a wind-proof down coat.

You also need to be aware of one thing: the weather usually changes quickly. The day might start sunny and clear; but by noon, heavy snowstorm may come. Therefore, it’s wise to arrange your itinerary flexibly and always have a plan B in hand.

Large Snowfall

December is the snowiest month in Sapporo, with an average precipitation of 136 mm from over 18 snowy days. The snow typically comes and goes throughout the day. If it’s light snow, you can walk around without an umbrella. But during heavy snowfall, it’s best to carry one. The snow can hit your face like rain, covering your coat and hair very soon. Alternatively, it’s a good idea to wear a hat and scarf to protect your head and face, or you’ll get wet once going indoor.

Although December temperatures aren’t as low as in January or February, the accumulated snow is already significant, with an average depth of about 132 cm. This transforms Sapporo into a magical white wonderland - even the simplest streets and buildings look very romantic and picturesque, which is ideal for relaxing strolls, sightseeing and photography.

Moderate Humidity

Sapporo experiences a moderate humidity level in December, around 69%. Visitors can enjoy fresh and crisp air when strolling outside.

Sunshine Hours & Daytime Hours

Sunshine Hours: about 3 hours/day
Sunrise: 6:45-7:06
Sunset: 16:00-16:09
Daytime Hours: 9 hours - 9 hours 15 minutes

Although Sapporo has relatively shorter sunshine hours, don’t ignore the influence of ultraviolet rays, because they reflect more strongly on snow than on ordinary road surfaces. So even on cloudy days, it’s still important to apply sunscreen, or wear sunglasses.

Rapidly shortening daylight hours require visitors to plan their trips very well. For example, it’s best to prioritize the key attractions, such as Sapporo Clock Tower and Hokkaido Prefectural Government Red Brick Building. At dusk, it’s recommended to head to JR Tower Observation Deck T38 to enjoy the fabulous snowy sunset view; it’s also nice to overlook the entire city illuminated by countless lights thanks to the Sapporo White Illumination.
