Winter holidays and summer weekends tend to command the highest prices in Telluride. August thunderstorms can briefly soak streets and trails, but the month is often dry, with an average humidity of about 10 percent. Aside from the occasional hot or cold spell, the temperature fluctuates between around 30 in January to 76 in July—milder, in general, than some other Colorado resorts farther north. There are so many summer festivals in Telluride that the town has designated one July weekend as the Nothing Festival—no staff, no passes, no schedule, no T-shirts, no nothing. Every other space on the calendar is taken up by mountain-themed films (Memorial Day), balloons (June), bluegrass (June), plein-air painting (July), jazz and mushrooms and chamber music and culinary arts (August), and the great Telluride Film Festival (Labor Day).
Like the rest of the Rockies, there’s a high-desert climate here, even if 300 inches of snow come down in a good winter. If it’s not snowing, it’s bright and sunny (some 300 days a year). And with an in-town elevation of 8,750 feet, that sun is strong. Bring plenty of high-SPF sunscreen. January brings the cold, but March brings the most snow and deepest bases on the mountain.
The shoulder seasons (October/November and April/May) are the quietest and the cheapest, since they fall in between ski area operations and everything else.
