Mountain in the Canadian Rockies on the border between Alberta and British Columbia

Mount Assiniboine is a mountain in the Continental Ranges (Canada). Its summit stands 3,618 m above sea level. Its prominence — how far it rises above the highest saddle linking it to a taller summit — is 2,086 m. It was first climbed in 1901.

From the lowest point within 5 km (1,730 m), it rises 1,888 m. The steepest side is the east face: 46° on average over the first kilometre. In places the ground near the top reaches 64° — terrain for climbers, not walkers.

Mount Assiniboine for skiers and climbers

Two scores out of 10, built only from open data — every part is shown. They describe what the mountain offers, not how safe it is.

Difficulty to the top

Alpine climb

Most path sections around the top are T6 on the SAC hiking scale. Glaciers around the top.

Indicative only — never a safety assessment. Conditions change: ask local guides and check the forecast.

Ski score

—

No ski runs within 12 km in OpenStreetMap.

How these scores are made

Ski (where OpenStreetMap has skiing within 12 km): up to 4 points for the length of downhill runs (300 km or more = 4), 1.5 for the number of lifts (40+), 1.5 for the vertical between lift stations (1,500 m) and 3 for the snow season — a month counts when the estimated mean temperature at the height of the ski area is −1 °C or lower and snow falls or lies there (NASA POWER, 2001–2020). Hiking & mountaineering: up to 2.5 for waymarked routes and paths, 1.5 for huts, 2 for the ascent from the valley (2,000 m), 1.5 for prominence (3,000 m), 1.5 for the season (months with summit afternoons above −5 °C) and 1 for via ferratas, climbing and glaciers. OpenStreetMap is built by volunteers: where few things are mapped, a score can be lower than reality.

Estimate for a normal year: average temperature and precipitation from NASA POWER, carried to each height, in a simple model of snow building up and melting. In a given year snow can come earlier or stay longer. It does not replace the local snow and avalanche bulletin.

Summit weather

Mount Assiniboine, month by month

Not a forecast: long-term averages (1991–2020), carried up to the summit. The orange line is where an average afternoon reaches 0 °C; above the dashed blue line it freezes even at dawn.

On an average July afternoon the summit reaches about 6 °C; on December nights it falls to about -29 °C. In 8 months of the year it stays below freezing at the top even in the afternoon. In July the 0 °C line climbs to about 4,620 m, above the summit: the top thaws on an average afternoon. Across the region, February is the driest month (42 mm) and June the wettest (121 mm).

Estimate: the NASA POWER climate of a ~55 km cell (average height 1,960 m), adjusted to the summit by −6.5 °C per 1,000 m. Rain, wet days and sunshine are those of the region. Mountain weather changes fast — always check a local forecast. ★ = mildest months at the top.
