Regarding the Highest and Lowest Temperatures in Hokkaido

Spring's sakura blossoms and autumn's momiji are only two examples of the plants that distinguish the four seasons in Japan.

As the northernmost part of the Japanese islands, Hokkaido has its own characteristic winter climate. The annual mean temperature in Hokkaido's largest city, Sapporo, is about 8.9℃, with the warmest temperature at 26.4℃ and occurring in August, and the coldest at -7.0℃ in January. Just from looking at these values, it is clear that midwinter in Hokkaido is exceptionally cold and prone to heavy snowfall, meaning that when visiting in winter it is absolutely necessary to bring sturdy winter clothing and snow boots.

January, February and March: Take Measures Against the Cold

日本へ観光するなら必見! 北海道の気温と服装について

In the entire year, the most severe winter weather recorded typically takes place from January to March in Hokkaido.

This intense cold, however, has lead to stunning snowy landscapes and thriving ski, snowboarding and other winter sports-based industries, and makes it a very popular place for winter sports enthusiasts to gather each year. Thanks to the influence of the 'seikototei', which is a high barometric pressure to the west and low pressure to the east effect, the area of Hokkaido on the Sea of Japan practically sees snowfall every day in the winter. On the other hand, the Pacific Ocean side of Hokkaido tends to have far more sunny days in the winter, but as a result, the relative dryness of the area may cause some to be less prepared for the weather and can result in people catching colds more easily. Protection against the cold as well as protection against aridity must be taken in equal measures during the winter in Hokkaido.

January: Hokkaido (Sapporo) Avg. of -3.6℃ (High of -0.6℃, Low of -7.0℃)

March: Hokkaido (Sapporo) Avg. of 0.6℃ (High of 4.0℃, Low of -2.9℃)

Hokkaido weather in March

While some signs of spring may start in March, the relative temperature in Hokkaido versus Honshu, the main island of Japan, is far lower still. It is a good idea to layer sweaters under coats still, and have proper winter accessories with you as well at this time. As the snow will begin to melt towards mid-March, it is a good idea to bring rain boots with you as well at this time.

April, May and June

Hokkaido weather in spring

Spring brings warm temperatures to Hokkaido.The snow continues to melt and the sakura bloom in April. However, it is still quite chilly at this time. In May, the temperature gradually increases and fresh green plants start to grow, filling this winter wonderland with spring-like scenery. From the latter half of May to June, the Okhotsk anticyclone effect comes into play, causing the weather to easily become chilly and wet within Hokkaido, and there is a tendency for the temperature to fluctuate rapidly during this time.

April: Hokkaido (Sapporo) Avg. of 7.1℃ (High of 11.5℃, Low of 3.2℃)

April in Hokkaido

The snow is usually completely gone by April in Hokkaido, but, though the temperature during the day is fairly warm by comparison, the early mornings and evenings are still quite chilly at this time. If you are planning on visiting during April, then it is a good idea to dress in layers, such as with extra jackets or sweaters, so that you can easily regulate your body temperature over the course of the day.

May: Hokkaido (Sapporo) Avg. of 12.4℃ (High of 17.3℃, Low of 8.3℃)

However, in the Kushiro and Tokachi and other westerly areas, the weather is still quite changeable and can get very cold during May, or there could be a lot of precipitation to contend with, meaning this month requires both winter items and rain gear.

June: Hokkaido (Sapporo) Avg. of 16.7℃ (High of 21.5℃, Low of 12.9℃)

June in Hokkaido

Not too hot and not too cold, June is the ideal month for sightseeing in Hokkaido.

There are increased chances of sudden rainstorms at this time, so it is also a good idea to bring a portable umbrella with you as well as you sightsee, just in case. And as the westerly weather conditions and effects from the Okhotsk anticyclone may still be felt, it would also be a good idea to bring a light coat or sweater with you, just to be safe.
