Regions
Climates we cover
Ten cold regions across the northern US, Canada, and the Nordics — each with its own temperature profile, charging network, and winter driving reality.
Minnesota
United States
Continental cold with long, bitter winters and occasional -30°C polar snaps. Consistent sub-zero nights are the norm from December through February.
Michigan
United States
Great Lakes cold with lake-effect snow bands that bring wet, wind-driven snow and sudden whiteout conditions, especially on the west shore.
Wisconsin
United States
Cold continental winters with frequent sub-zero stretches and lake-effect snow near Lake Michigan and Lake Superior.
Colorado (mountains)
United States
High-altitude cold with big temperature swings, mountain passes, and strong sun. Altitude itself has little direct effect on battery chemistry, but sustained climbs drain range fast.
Ontario
Canada
Humid continental cold with lake-effect snow near the Great Lakes and long freezing spells. Road salt is heavy.
Quebec
Canada
Severe, dry continental cold with some of North America's most reliable sub-zero winters. Winter tires are mandatory by law.
Alberta
Canada
Extreme continental cold with chinook-driven temperature swings. Calgary and Edmonton winters routinely hit -25°C to -30°C with bitter wind chills.
Rural Norway
Norway
Coastal and fjord cold with elevation changes and wet, icy conditions. Winter is long but less extreme than continental interiors thanks to the Gulf Stream.
Sweden / Finland
Nordics
Arctic-adjacent continental cold with long, dark winters and deep, persistent snow. Winter tires are mandatory and studded tires are common.
Alaska
United States
The harshest cold on this list — interior Alaska reaches -35°C to -40°C with extreme wind chills and very long, dark winters.
Wyoming
United States
High-plains cold with brutal wind chill — Wyoming's near-constant wind makes the effective cold feel worse than the thermometer alone suggests.
Montana
United States
Big-sky cold with sharp regional swings — mountain valleys and the eastern plains can differ by 10°C+ on the same day.
North Dakota
United States
Open-plains cold with some of the harshest wind chill in the Lower 48 — few natural windbreaks mean sustained, biting winds all winter.
Vermont
United States
New England cold with heavy lake-effect and mountain snow — frequent snowfall adds rolling resistance on top of the battery's own cold losses.
Maine
United States
Coastal-to-interior cold with heavy nor'easter snowfall; the interior and northern reaches get notably colder than the coast.
Idaho
United States
Mountain-and-valley cold with sharp local variation — the Snake River plain is milder than the mountainous panhandle and central highlands.
Manitoba
Canada
Prairie cold with extreme wind chill — Winnipeg is one of the coldest major cities in North America, with long stretches below -20°C.
Saskatchewan
Canada
Open-prairie cold similar to Manitoba's — flat terrain offers little wind protection, so wind chill regularly makes conditions feel far colder.
