Denver experiences a semi-arid climate. The weather is heavily influenced by the Rocky Mountains to the west, and can be unpredictable. Winters in Denver tend to be cold, with average temperatures ranging between 17°F (-8°C) and 46°F (8°C). Snow is common in December and January, which makes Denver ideal for winter sports enthusiasts.

The Mile High City boasts more than 300 days of sunshine annually, and the summers are generally hot and dry. The temperatures range between 50°F (10°C) and 89°F (32°C). Rainfall is low, and days are cloudless and sunny. The relatively mild weather is partly due to the city's altitude – 5,280 feet (1.61 km) above sea level.

Late spring and early summer bring massive storms to the city. Fronts, moisture and strong winds all build together, creating thunder and hailstorms that can sometimes cause severe damage.
