Weather InformationDenver experiences four mild seasons, with an arid climate. Summers bring warm weather and low humidity, offering comfortable afternoons and evenings. The spring and fall are pleasant, perfect for an afternoon hike or a day of leaf-peeping. Aspen fall foliage is at its peak from mid-September until mid-October. Winter temperatures can get fairly cold, with highs averaging 48 degrees. Snow may fall, especially in March, but it rarely stays on the ground for very long. Chinooks, or mountain winds that gain heat as they lose elevation, help warm up the winters, occasionally raising the daily temperature to 60 degrees. The city receives an average of 18 inches of preceiptation annually.
Crowd InformationSummer is a peak time for crowds and conventions, and hotels in the downtown area frequently sell out with business clientele, but the exact dates vary by year.
Closure InformationHotels, shops, and attractions remain open year-round.
When to SaveNovember through March is the best time to save a little extra cash, especially for hotels, while July and August tend to the most expensive months due to higher demand. Packages, however, are available year-round on a week-to-week basis. Airfare prices also tend to drop in the winter, even with the rise in ski tourism, because of fewer business and leisure visitors overall.
