Hokkaido may be just one prefecture, but its vast size—about twice that of Taiwan—means the weather can vary noticeably between regions like Sapporo, Asahikawa, and Hakodate. If you’re planning to travel across areas, it’s worth checking local forecasts and preparing for different conditions. Here we’ve compiled weather data for Hokkaido’s main sightseeing spots to guide your planning.

Autumn here feels very different from much of Asia. By September, average temperatures already fall below 20°C (68°F), and by November they often dip under 10°C (50°F). For travelers from places like Singapore, Hong Kong, or southern China, this may feel closer to winter than autumn. Visitors from the U.S. East Coast might find it comparable to early November in New England, while Europeans may recognize the crisp chill of northern France or Germany in late autumn. Snow can arrive as early as November in some areas, adding a wintry charm that sets Hokkaido apart from the rest of Japan.

Warm clothing is essential, and if you’re driving, make sure your rental car is equipped with snow tires and winter gear. Public transportation may also be delayed or suspended due to snow, so keeping your schedule flexible is wise.

Because Hokkaido is so large, weather conditions vary slightly from region to region. What’s consistent, however, is that once autumn begins, average temperatures drop below 20°C (68°F). With moderate humidity, the climate feels pleasantly crisp and is ideal for sightseeing. While you won’t see snow in the lowlands yet, a trip into the mountains may reward you with an early glimpse.

For travelers coming from hotter parts of Asia, September in Hokkaido will feel refreshingly cool. If you’re flying in from a warm climate, it’s smart to keep a light jacket in your carry-on so you’re comfortable when you arrive. Visitors from North America or Europe might find the weather similar to early fall in the Pacific Northwest or northern Europe. To prepare for sudden showers, a compact folding umbrella is a handy item to bring along.

As September cools down in Hokkaido, it’s the perfect time to get outdoors and explore without the discomfort of summer heat. For travelers who don’t drive or prefer not to juggle luggage on public transport, local bus tours are a great option—just hop on, relax, and enjoy the sights without worrying about directions or train connections.

While the autumn leaves haven’t arrived yet, the mild weather makes sightseeing especially enjoyable. Visit Noboribetsu Jigokudani (Hell Valley) to see steaming volcanic landscapes, or take in the wide-open views of Lake Toya for a refreshing escape. Prefer to stay closer to the city? Sapporo offers plenty of shopping and dining, along with a visit to the Historical Village of Hokkaido for a fascinating glimpse into the region’s past.

By October, temperatures in Hokkaido often hover around 10°C (50°F), similar to a winter cold snap in much of East Asia. This is the time to bring out sweaters, HEATTECH layers, and even pocket warmers. The good news is that Hokkaido is well-prepared for the cold—many stations connect directly to department stores and sightseeing spots via underground walkways, and indoor heating makes being inside surprisingly cozy. If most of your trip is indoors, layering your clothing is best so you can adjust easily without overheating.

Because the difference between indoor and outdoor temperatures can be sharp, remember to bring any regular medications to avoid feeling unwell. October also sees more rainfall than September, so rain gear is another must-pack item.

From late September through early October, Hokkaido transforms into a canvas of autumn colors. If you want to catch the earliest fall foliage in Japan, October is the perfect time to visit. Spend your days surrounded by vibrant maples and golden ginkgo, then savor fresh Hokkaido seafood in the evening for the ultimate seasonal experience.

Near Sapporo, Jozankei Onsen is a popular spot to enjoy hot springs alongside colorful leaves, while the Sounkyo Gorge in Daisetsuzan National Park offers breathtaking views of mountainsides covered in crimson. To round out your trip, extend your journey to Otaru, where charming streets, souvenir shops, and local delicacies make for a relaxing and memorable day.

By November, Hokkaido’s temperatures drop below 10°C (50°F), and in higher-latitude or mountainous areas, it can even dip below freezing. For travelers from tropical regions, this feels like the depths of winter, so winter gear such as HEATTECH layers, fleece-lined clothing, and long boots are essential. The chill also brings with it the first chance to enjoy Hokkaido’s magical snowy landscapes.

Once snow arrives, roads and sidewalks can become slippery, so non-slip, waterproof footwear is especially important. This is crucial for children and older travelers—consider slip-resistant boots or attachable ice grips to stay safe while savoring the romance of Hokkaido’s early winter scenery.

Snow begins to fall in Hokkaido in November, though ski season doesn’t usually get underway until December when the powder snow is at its best. Early snow can be hit or miss this month, and activities like ice fishing or full-scale winter sports also start later in the season.

Still, November offers its own charm. Head further north for a better chance of catching snowfall, or visit the magical Blue Pond in Biei, where the landscape transforms into a dreamlike scene under a dusting of white. Even without deep snow, the quiet scenery and early hints of winter create a romantic atmosphere unique to Hokkaido at this time of year.

Because of its higher latitude and cooler climate, autumn leaves in Hokkaido usually begin from mid-September through early October—earlier than in most other parts of Japan.

Snowfall varies by region, but in general, the first snow begins in November. If you visit in mid to late November, you may catch some snowy scenery, but for skiing you’ll need to wait until December when the snowpack is deeper.

Yes. Average temperatures drop below 20°C (68°F) in September and can fall below freezing by November. For visitors from warmer parts of Asia, this will feel very cold, so bring proper winter clothing.

Hokkaido’s autumn is much colder compared to many Asian regions, but that’s also what makes its scenery so unique. With the right layers and winter gear, you’ll be able to fully enjoy the beauty and atmosphere of an autumn trip to Hokkaido.
