Eagle River has a subarctic climate.
Short, cool summers and long, cold winters — here's what that means in plain terms.
What this climate feels like
The four things a regular visitor actually wants to know:
Highs near 19°C in July.
Lows near −13°C in January. About 187 freezing nights a year.
About 449 mm of rain a year, plus 179 cm of snow. Snow falls through the winter months.
Cloudy skies much of the year.
What "subarctic" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. Eagle River's type — subarctic — sits in the broad family of four-season continental climates.
Researchers write climate types as a short letter code. Here is what each letter means:
Cities with the same climate as Eagle River
A subarctic climate (Dfc) — these recognizable cities share it. If you know one of them, you know roughly what to expect.
Eagle River sits near a climate boundary
This city sits right on the line between subarctic and the next type along. Different climate maps file it on different sides of that line; the lived weather doesn't change at the line — it's a naming boundary, not a wall.
Has Eagle River's climate type changed?
Stable — Eagle River's climate has held the same type between the 1971–2000 and 1991–2020 normals. The label is steady; the climate beneath it is still warming.
What this climate means for you
70–120 day growing season — short-season vegetables, hardy berries, potatoes. Greenhouses are common.
Summer is the only practical outdoor window. Winter travel is possible but cold-adapted (ice roads, snowmobiles, aurora viewing).
Long, brutal winters and a brief but precious summer. Heating dominates the year; permafrost shapes construction.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Eagle River's measured 30-year climate normals (1991–2020) — the same official records behind Eagle River's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
