Long-term temperature, precipitation, and daylight patterns from representative coordinate measurements
This climate profile presents twelve-month atmospheric data for Gladys Lake Ecological Reserve in British Columbia, covering the period from 1991 to 2020. Metrics include average minimum, mean, and maximum temperatures alongside precipitation rates, relative humidity, wind speeds, and daylight hours. These values originate from a single representative coordinate and illustrate long-term climatological trends rather than current weather or forecasts.
Long term monthly temperature averages alongside daily precipitation rates across twelve months
Compare twelve months of average temperature bounds, daily precipitation rates, and daylight hours across the protected landscape.
