September 2025 brought a classic Colorado blend to Boulder and the Front Range: near-normal temps, wetter-than-average skies, and a lively mix of sunshine and storms.

The month eased us gently into autumn, with crisp mornings, comfortable afternoons, and brilliant foliage lighting up the higher terrain.
