The arrival of fall colors is just weeks away in Colorado, sure to put on a show worth planning a trip into the mountains for.
As far as timing goes, expect the first fall colors to show up around September 10 this year, according to Explore Fall. Peak fall colors, however, will come much later – and you’ll want to wait to plan your trip for then.
Two big questions related to when fall colors will appear and how long they’ll stick around tend to be temperature and precipitation. The arrival of lower nighttime temps tends to be what triggers the appearance of brilliant yellows, oranges, and reds among Colorado’s foliage, with drier conditions – which have been present in Colorado this year – often meaning an earlier transition in the trees.
