Petroglyph Provincial Park Annual Climate Normals: Monthly Temperature, Precipitation, and Wind Patterns

Access twelve-month climate averages for Petroglyph Provincial Park in British Columbia, covering the period from 1991 to 2020. Data points include mean, minimum, and maximum temperatures alongside precipitation rates, relative humidity, wind speed, and daylight hours. These values represent long-term atmospheric patterns at a single sampled elevation of 158.92 meters and do not reflect current weather or localized microclimate conditions across the entire park area.
