Mid-September through October, or March through April. WeatherSpark identifies the third week of September as the single best week in Sedona's year for outdoor travel — blue skies, low humidity, daytime highs around 85°F and cooling evenings. Spring (March–April) is the second-best window with highs in the mid-60s to low-70s and wildflower blooms. Both windows avoid summer monsoon thunderstorms and winter cold snaps, and coincide with the Sedona Plein Air Festival (October) and Film Festival (February–March) for cultural depth
