When Does It Snow in Sapporo? First & Last Snowfall Dates Guide

When Does It Snow in Sapporo: Season at a Glance

Sapporo's snow season stretches roughly six months — from mid-November through early April. The Sapporo Regional Meteorological Observatory (札幌管区気象台) has tracked snowfall since 1877, giving us one of the longest snow records in Japan. For travelers asking when does it snow in Sapporo, the short answer is: earlier and longer than most expect.

According to JMA climate data, Sapporo receives about 600 cm (236 in) of cumulative snowfall per season, concentrated heavily between December and February. That makes it one of the snowiest major cities in the world — on par with cities in northern Canada. For a broader picture of Hokkaido's weather patterns, see our complete Hokkaido weather guide.

Here is a quick overview of Sapporo's snow season:

Month	Snow Status	Typical Ground Depth
November	First snowfall (初雪) arrives mid-month	0–10 cm
December	Steady accumulation begins	20–40 cm
January	Heavy snowfall, deepening snowpack	60–80 cm
February	Peak depth, Snow Festival season	80–100 cm
March	Snowfall tapers, slow melt begins	40–60 cm
April	Snow disappears by early-to-mid month	0–10 cm

First Snowfall Dates and What They Mean for Visitors

Sapporo's first snowfall (初雪) — the first observed snowflake at the official observatory — arrives around November 12 on average. This has remained remarkably consistent over 140 years of records, according to JMA observation data. The latest recorded first snowfall was November 20, a date reached in both 1890 and 2018.

However, first snowfall and first accumulation are different things. The initial snowflakes typically melt on contact. Meaningful ground accumulation usually begins in late November or early December. If you are visiting Sapporo specifically for snow, do not count on a white landscape before late November.

For context, the first snowfall date is still tracked as a semi-ceremonial event in Sapporo. Local news announces it each year, and it marks the psychological start of winter for residents — even though weeks may pass before the city turns truly white.

Month-by-Month Snowfall in Sapporo

November: The First Flurries Arrive

The first snow typically appears around November 12, but accumulation is minimal. Most days in November still see bare pavement in the city center. Temperatures hover around 3–5°C during the day and dip just below freezing at night. Snow-dependent activities like skiing are not yet available in the city, though some mountain resorts may open by late November.

December: Winter Sets In

December is when Sapporo transforms. Snowfall becomes regular, and ground depth builds from near zero to 30–40 cm by month's end. The famous Sapporo White Illumination lights up against a snowy backdrop. Transportation adjustments begin — buses may run late, and sidewalks become icy. This is also when New Chitose Airport starts seeing weather-related flight delays and cancellations.

January–February: Peak Snowfall and Snow Festival Season

These two months account for the bulk of Sapporo's snow. Ground depth reaches 80–100 cm (31–39 in) by mid-February, and fresh snowfall is frequent. The Sapporo Snow Festival (さっぽろ雪まつり) takes place in early February, relying on this deep snowpack for its massive snow and ice sculptures. According to official festival information, organizers supplement with machine-made snow if natural accumulation is low, so the event proceeds regardless of the season's timing.

January sees the coldest temperatures, with daytime highs around -1°C and overnight lows near -7°C. Snowfall can be heavy and sudden — 20–30 cm in a single day is not unusual. For Hokkaido-wide snowfall statistics, the peak months follow a similar pattern across the island.

March: The Long Thaw Begins

Snowfall continues into March but becomes lighter and less frequent. Temperatures climb above freezing during the day, starting a gradual melt. Ground depth drops from around 60 cm at the start of March to under 20 cm by the end. For more details about late-season conditions, see our guide on what to expect in Sapporo in March.

March is a transitional month — you will still see plenty of snow, but the city feels like it is slowly waking from winter. Roads become slushy during the day and refreeze at night, creating icy conditions that catch visitors off guard.

When Does the Snow End: Last Snowfall and Melt Dates

Sapporo's last snowfall typically occurs in late March or early April. According to JMA monthly statistics, the last measurable snow on the ground disappears by early-to-mid April on average. By late April, the city is snow-free and cherry blossom season begins.

This timeline matters for two types of travelers. If you want guaranteed snow, visit between mid-December and late February. If you want to avoid snow entirely, late April through October is your window. The gap between — March through mid-April — is unpredictable, with lingering snowpack but increasingly spring-like conditions.

One common mistake is visiting late March expecting a full winter wonderland. By that point, the snowpack is in active decline. The city is still cold, and patches of snow remain, but the deep, photogenic drifts of January and February are gone.

How Sapporo Snow Timing Affects Travel Planning

Best Months for Snow Activities

For snow-dependent activities, January and February are the most reliable months. Ski resorts around Sapporo operate at full capacity, the Snow Festival draws millions of visitors, and the city's snow-covered streetscape is at its most photogenic. December is also good, though early December can still be building up.

When to Visit if You Want to Avoid Snow

Sapporo is effectively snow-free from late April to late October. May through September brings mild to warm weather with no snow concerns. For a comprehensive view of what each season looks like, check our full Sapporo weather overview by season.

Packing for Sapporo's Snow Season

What you pack depends on your visit month:

• December–February: Insulated waterproof boots with good traction are essential. Layered clothing with a windproof outer shell, thermal underlayers, and warm accessories (gloves, scarf, hat) are non-negotiable.
• November/March: Lighter winter gear works, but waterproof shoes are still a priority. Temperatures swing above and below freezing daily.
• April: Light jacket and regular shoes suffice by mid-month, though residual ice patches linger on shaded sidewalks.

Getting Around Sapporo During Heavy Snow

Sapporo's subway system is the most reliable way to travel during heavy snow — it runs underground and is unaffected by weather. The Namboku, Tozai, and Toho lines cover the city center and major districts.

Buses and streetcars (trams) do operate in winter but are subject to delays during heavy snowfall. Many visitors on Reddit recommend building extra time into your schedule if relying on surface transit during December through February.

Flights into New Chitose Airport face the most disruption between December and February. Heavy snowfall can ground flights or cause multi-hour delays. If traveling during peak snow months, consider building a buffer day into your itinerary. The airport is connected to central Sapporo by JR Rapid Airport train, which takes 37 minutes and costs ¥1,150 (~$8). Rail service is more weather-resilient than flights, though extreme snowfall can slow trains as well.

Walking in Sapporo during winter requires caution. Sidewalks are cleared regularly but can be icy, especially in the morning. Many locals use clip-on shoe spikes (available at convenience stores for around ¥500–1,000 / ~$3–7) for better traction.
