Saskatchewan Road Conditions and Highway Weather

Major highways in Saskatchewan

The corridors this page follows, each with its own page. Surface and temperature are the latest readings along the whole road; the summits are where the same road is a different drive.

• Highway 1 (Trans-Canada) — The Trans-Canada across the open prairie from the Alberta line through Swift Current, Moose Jaw and Regina to Manitoba: four lanes, no shelter, and the ground blizzards that close it between Moose Jaw and Regina.
• Highway 11 (Louis Riel Trail) — Regina to Saskatoon and Prince Albert, the road between the province's two cities: divided the whole way and as open as the Trans-Canada, with the same blowing snow.

Closures and road work are not yet imported for Saskatchewan; Highway Hotline carries them. No weather warnings from Environment and Climate Change Canada are in force as of Sep 20, 2026 5:33 AM CST.

Saskatchewan Winter Tire Rules

Saskatchewan has no winter tire law and no rule about studded tires: the Vehicle Equipment Regulations set tread depth and inflation and say nothing about the season, and SGI has said a winter tire law is not being considered. What the province does is define the words: on the Highway Hotline "travel not recommended" means visibility under 250 metres or a road that could become impassable, and it is the closest thing to a rule a prairie winter has.

What the law says

No Saskatchewan law requires winter tires on a passenger vehicle, and none restricts studded tires: The Vehicle Equipment Regulations, 1987 require tires with adequate tread, properly inflated and free of damage, and that is the whole of the tire law. SGI and CAA Saskatchewan recommend winter tires; about half the province's drivers use them. You are required to drive to the conditions.

Studded tires

Studded tires are legal in Saskatchewan all year: the regulations carry no provision on them. Manitoba, next door, allows them only from 1 October to 30 April, and most US states to the south restrict them by season, so a driver leaving the province on studs should check the rule at the line.

How you will know it is active

• The Highway Hotline, whose winter terms are defined -- "covered", "swirling snow", "drifting snow", "travel not recommended" -- and whose closures are the ministry's
• RCMP travel advisories in a blizzard, which in Saskatchewan usually mean stay where you are
• Environment and Climate Change Canada's blowing snow and blizzard warnings

There is no seasonal switch here. What changes is the wind, and Highway Hotline ↗ is the province's own account of what it has done to the road before you set off.

When roads get bad in Saskatchewan

What the road normally throws at you, month by month, from Environment and Climate Change Canada's 1981–2010 normals at Regina International Airport, Saskatoon Diefenbaker International Airport, Swift Current and Prince Albert Airport — four stations, four climates, and each month names the worst of them and the place that measured it. This is what the month is usually like, not a forecast and not a rule.

• Jan Freezing rain Freezing rain on about 2.2 days a month somewhere on the network, and 31 nights below freezing at Regina.
• Feb Freezing rain Freezing rain on about 1.8 days a month somewhere on the network, and 28 nights below freezing at Saskatoon.
• Mar Freezing rain Freezing rain on about 2.0 days a month somewhere on the network, and 30 nights below freezing at Prince Albert.
• Apr Freezing rain Freezing rain on about 0.7 day a month somewhere on the network, and 22 nights below freezing at Prince Albert.
• May Cold nights 8 nights below freezing at Prince Albert; the high passes can still see snow.
• Jun Rain and fog Frost is rare even at Prince Albert, the coldest of the four; the hazards are rain, fog and the odd summer storm.
• Jul Rain and fog Frost is rare even at Prince Albert, the coldest of the four; the hazards are rain, fog and the odd summer storm.
• Aug Rain and fog Frost is rare even at Prince Albert, the coldest of the four; the hazards are rain, fog and the odd summer storm.
• Sep Cold nights 6 nights below freezing at Prince Albert; the high passes can still see snow.
• Oct Freezing rain Freezing rain on about 0.9 day a month somewhere on the network, and 23 nights below freezing at Prince Albert.
• Nov Freezing rain Freezing rain on about 2.4 days a month somewhere on the network, and 29 nights below freezing at Prince Albert.
• Dec Freezing rain Freezing rain on about 2.1 days a month somewhere on the network, and 31 nights below freezing at Regina.

The Highway Hotline is the road conditions service run by the Saskatchewan Ministry of Highways, at hotline.gov.sk.ca. It is the province's own account of its highways, in its own vocabulary, and it publishes:

• The winter condition of every provincial highway section in the ministry's own terms: bare, partly covered, covered, ice, drifting snow, swirling snow, travel not recommended
• Closures, incidents, construction and the ferry and border status
• Highway cameras and the position of the plows
• The same conditions by phone at 511 in Saskatchewan or 1-888-335-7623

Highway Hotline and the conditions on this page

The Hotline reports what the ministry's crews have seen and declared for each section — covered, drifting snow, travel not recommended — and "travel not recommended" is its own defined term: visibility under 250 m or a road that could become impassable. What this page adds is the layer under those declarations — the surface condition estimated along the whole road from radar and analysis, and the wind, which on the prairie is the number that says whether the snow already down is about to move.

Saskatchewan Winter Driving FAQ

Are winter tires mandatory in Saskatchewan?

No. Saskatchewan has no winter tire law and SGI has said one is not being considered — hard to enforce, and a cost to drivers. About half of the province's drivers fit them anyway, on SGI's own survey, and SGI and CAA recommend them. What the law does require is that you drive to the conditions.

What does "travel not recommended" mean on the Highway Hotline?

It is a defined term, not a mood: visibility under 250 metres, or a highway that could become impassable from ice, snow, drifts or an extreme weather event. The Hotline's other winter terms are defined too — "covered" means all four wheels are on snow or ice, "swirling snow" is loose snow lifted by traffic, "drifting snow" is the wind moving it. Saskatchewan has no 511; the Hotline is the name to look for.

Why does Highway 1 close between Regina and Moose Jaw?

Blowing snow. The 70 km between the two cities cross open, treeless prairie, Regina averages 19 days a year of blowing snow on the 1981–2010 normals, and when a west wind picks up the snow already on the ground the visibility goes to nothing on a clear day — the Hotline closed the road for zero visibility on 6 February 2025 and again in the January 2026 storm. There is no sheltered alternative; the RCMP's advice is to wait.

How cold does it get on Saskatchewan highways?

Colder than anywhere else on this site. January averages −15.5 °C at Saskatoon and −14.7 °C at Regina, with mean overnight lows near −20 °C and 26 or 27 days a month that never rise above freezing. Salt stops working below about −10 °C, so the roads are sand and packed snow from December to March, and a stranded car is an emergency within the hour.
