September through October (fall). Fall offers mild temperatures (highs in the low 60s°F), smaller crowds than summer peak, lower hotel rates, the Fiesta de Santa Fe in early September (including Zozobra), golden aspen foliage in the Sangre de Cristo Mountains, and the continuation of the arts season. US News Travel and Lonely Planet both cite September–November as the best window for comfortable weather and reduced congestion
