According to the Köppen climate classification system, Dallas Peak is located in an alpine subarctic climate zone with long, 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 south into the San Miguel River, and north to the Uncompahgre River via Dallas Creek.
