Sapporo weather at a glance

  • Sapporo, in Hokkaido, is one of the coldest major cities in Japan, with true winter travel centered around snow.
  • From late November to March, snow is on the ground for long stretches, and in January-February, “feels like” temperatures below −10°C are common.
  • Summer is short and cool, making Sapporo a popular “escape from the heat” destination.
  • The rainy season is weaker than on the main island, but July-September can still see wetter, more humid days.
  • Because snow festivals, skiing, hot springs, and seasonal foods differ by time of year, choosing when to visit is important.
Jan · Feb

City of snow and ice — a true winter trip

Avg low −7 to −6°C / high −1 to 0°C · Snow/rainy days: 20+ per month / precipitation (mostly snow) 100 mm+

  • Almost every day has falling snow or snow piled on the streets—full winter conditions.
  • Including wind chill, “feels like” temperatures of −10 to −15°C are common, and poor gear makes outings painful.
  • The snowy scenery is beautiful, but you must account for slippery streets and snow removal work.

Suggested outfits

  • · Heavy winter parka (long down strongly recommended)
  • · Two thermal layers + knit or hoodie
  • · Waterproof boots, thick socks, scarf, gloves, ear warmers

A note for travelers

Even if you come mainly for skiing or the snow festival, prepare as if you will be walking long distances in full winter conditions.

Mar · Apr

Drawn-out late winter — real spring arrives late April

Avg low −3 to 3°C / high 4-11°C · Snow/rainy days: 15-20 per month / precipitation 70-90 mm

  • March still feels like winter, with leftover snow and cold air.
  • Even in April, mornings and evenings can be near freezing, and occasional snow is possible.
  • Melting snow and ice make some paths muddy or slippery, so waterproof shoes are ideal.

Suggested outfits

  • · Thick coat or padded jacket
  • · Knit or hoodie
  • · Waterproof, slip-resistant shoes

A note for travelers

Rather than assuming “it’s spring so it must be warmer,” pack as if for January-February in Korea.

May · Jun

Finally feeling like spring — cool but still a bit chilly

Avg low 6-10°C / high 15-20°C · Rainy days: 10-12 per month / rainfall 60-90 mm

  • Snow in the city disappears, and parks and streets start turning green.
  • Days feel warm, but mornings and evenings can still be quite cool, so layering is needed.
  • It’s a great temperature range for relaxed walks and nature sightseeing.

Suggested outfits

  • · Light coat or windbreaker
  • · Shirts, knits, or sweatshirts
  • · Comfortable sneakers

A note for travelers

Warm sunshine can suddenly turn into chilly shade or evening air, so keep an outer layer with you.

Jul · Aug

Short, cool summer — perfect for escaping the heat

Avg low 16-19°C / high 23-26°C · Rainy days: 10-13 per month / rainfall 90-120 mm

  • While other parts of Japan suffer from heat waves, Sapporo is known for its pleasant summer.

  • Sudden rain or overcast days can still feel a little cool.

Suggested outfits

  • · T-shirts or light long sleeves
  • · Light shirts or cardigans
  • · Light pants or skirts

A note for travelers

If you want to enjoy outdoor walks, cycling, or picnics without extreme heat, July-August is perfect.

Sep · Oct

Crisp air and vivid foliage — highlight of autumn

Avg low 9-12°C / high 18-20°C · Rainy days: 10-12 per month / rainfall around 100 mm

  • September feels like early autumn, while October brings deeper colors and a strong autumn atmosphere.
  • The air is clear and calm—ideal for walks, photography, and hot springs.
  • Mornings and evenings become quite chilly, so you’ll feel cold without a proper outer layer.

Suggested outfits

  • · Medium-weight jackets or coats
  • · Knits or sweatshirts
  • · Warm socks and sneakers

A note for travelers

Autumn is popular for hot springs and nature spots, so allow extra time for travel and reservations.

Nov · Dec

Back into snow and winter — prepare for the cold again

Avg low −4 to 0°C / high 1-5°C · Snow/rainy days: 15-20 per month / precipitation (mostly snow) 80-110 mm

  • Temperatures drop quickly from early November, and snow starts to accumulate from mid-month.
  • By December, Sapporo is fully in winter mode and heavy winter clothing is necessary.
  • There are many icy patches on paths and roads, so footwear really matters.

Suggested outfits

  • · Thick padded jacket or coat
  • · Fleece or thermal inners and knits
  • · Waterproof, anti-slip boots and winter accessories

A note for travelers

Early winter Sapporo “looks” fully wintry in photos—perfect for scenery, but over-preparing your winter gear is better than under-preparing.
