According to the Köppen climate classification system, Stony Mountain is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers.[5] Due to its altitude, it receives precipitation all year, as snow in winter, and as thunderstorms in summer, with a dry period in late spring. Precipitation runoff from the mountain drains into tributaries of the Uncompahgre River.
