Insider timing tips

  • Denver's high altitude means sunshine is intense year-round, even in winter. Pack sunscreen.
  • The 'monsoon season' from July to September can bring intense, short-lived thunderstorms, often in the afternoon, which can affect mountain travel.
  • Spring (March-May) weather is highly unpredictable. Ski resorts may still be open in March, while summer-like conditions can appear in May.
  • Shoulder seasons (April-May and September-October) offer a good balance of pleasant weather, fewer crowds than summer, and more reasonable prices.
  • While Denver itself sees less snow than many expect, mountain passes to ski resorts can be treacherous in winter and early spring.
