Spring arrives relatively late in Eastern Hokkaido compared to the rest of Japan. In March, snow scenery remains, and heavy snowfalls can still occur. By late April, temperatures start to exceed 10°C, making spring outerwear comfortable. However, snow typically doesn't completely disappear until after Golden Week. In May, average temperatures rise to around 14°C, and cherry blossoms finally begin to bloom. However, temperatures can drop to around 3°C overnight and into the early morning, creating significant temperature differences. For early spring tourism in Eastern Hokkaido, winter attire might be reassuring.

In Eastern Hokkaido, temperatures fluctuate until around June. Some days feel as cold as early spring, while others resemble the heat of midsummer. Unlike mainland Japan, Hokkaido doesn't experience the typical rainy season but is known for its dry climate. However, from mid to late June, there's a period called "Ezo Tsuyu," characterized by increased rainfall. It's only temporary, so it might be an ideal travel destination for those looking to escape the humid air. From around July, the true summer begins, and temperatures continue to rise. The average temperature in July is about 20°C, and in August, it's around 30°C, but temperatures can vary greatly depending on the area. For example, in Kushiro, known as the "laughably cool city," the average summer temperature is around 20°C, with only 1 or 2 days exceeding 30°C each year. In contrast, Kitami, located in a basin, experiences summer temperatures mostly around 30°C, with many days exceeding 35°C. However, the humidity is low throughout Eastern Hokkaido, so even on hot days, the sticky discomfort is minimal. You might need a light jacket in the evenings depending on the location, so it's recommended to check the climate of your stay area in advance and adjust your clothing accordingly.

In recent years, Eastern Hokkaido has been strongly affected by lingering summer heat. There are many hot days until early September, with temperatures occasionally approaching 30°C. By late September, it gradually starts to feel like autumn, yet it's reassuring to have a short-sleeve option in your luggage. In October, the average temperature drops to around 11°C, making outerwear necessary to keep warm. By November, it feels almost like winter, and there may even be days when you encounter the first snowfall. This season sees an increase in outdoor walks to admire the beautifully colored autumn leaves, so having a jacket or windbreaker that can effectively block the cold air is comforting. Even if it's warm during the day, nights can feel like winter, so be mindful of your sleepwear.

In December, temperatures begin to drop below freezing, marking the arrival of a true winter. Snow starts to fall in early December, and by the end of the month, there is significant snow accumulation. Eastern Hokkaido typically experiences less snowfall, but the area is prone to "ice burn" conditions where roads become icy. To prevent slipping, it's reassuring to wear winter shoes with rubber soles. Be cautious with shoes that have metal fittings, as they can be slippery indoors. January, often referred to as "Doto Hare," is characterized by many sunny days. The sunlight reflecting off the snow can be dazzling, and there is a risk of "snow burn," or sunburn caused by UV rays, so be careful. In the winter of Eastern Hokkaido, prioritize "safety first!" It's not just "cold," it can feel downright "painful." Protect your skin from exposure by using gloves, scarves, and hats. Coastal cities like Abashiri and Kushiro, which face the sea, experience lower perceived temperatures due to the sea breeze, so using items like warmers can help as a countermeasure. Buildings in Hokkaido are highly insulated, making indoor environments much warmer compared to the bitter cold outside, so it's best to wear layers that are easy to take on and off.

Here's a video introducing recommended clothing for each season! Consider it for choosing your outfits.

When enjoying outdoor activities all year round, make sure to take proper precautions against the cold. In Eastern Hokkaido, even on summer days when it feels hot enough to wear short sleeves, the temperature can drop to freezing at night. No matter how warm it gets during the day, never forget to bring a jacket. Bug spray is also reassuring, especially for summer outdoor activities. Nature-rich areas mean you're likely to encounter insects when you move a bit away from city areas. Mosquitoes are especially prevalent near water, so be well-prepared. In winter, aside from wearing warm clothing, adhesive body warmers are also recommended. Stick them under your neck or on your waist to keep your body warm. A characteristic of Eastern Hokkaido is that you might suddenly find yourself in areas with heavy snowfall when you move around. Snow boots that cover your ankles are essential for stress-free exploration.
