Long-term normals for temperature, precipitation, humidity, and daylight cycles
Detailed monthly climate normals for Great Glacier Provincial Park, based on a representative coordinate at 945 meters elevation. These records provide a thirty-year baseline from 1991 to 2020, covering average temperature ranges, precipitation rates, relative humidity, wind speed, and daylight hours. The data represents long-term patterns rather than current weather, reflecting the consistent atmospheric profile of this mountainous region in British Columbia.
Long-term monthly averages trace thermal variation and daily precipitation rates across the year.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
