Colorado is known for the Rocky Mountains but almost 40% of its area consists of the eastern high plains. The interior continental location of Colorado, the high elevation, and the mountains are of major importance to the climate of the state. Furthermore, two huge river valleys dissect eastern Colorado; the Arkansas River to the southeast and the South Platte River in the northeast of the state. These features have a great influence on wind patterns, storm tracks, and temperatures.
Denver, the capital of the state of Colorado, has a climate that is typical for the western great plains: a steppe climate. In a roundabout way you could say a steppe climate for Colorado means light precipitation throughout the year, gradually increasing towards Kansas and Nebraska. Dry winters, spring and summer are wetter, often windy, very changeable weather, and an occasional monstrous thunderstorm that might come with damaging hail.
Denver experiences a 4 season climate with more than 300 days of bright sunshine. Spring in Denver starts late and is subsequently brief. In April, for example, the city could still be coated with snow. However, spring comes with rapid changes in the weather patterns. A sunny day in spring could sometimes bring a temperature of 70 degrees and be followed by 32 degrees the next day.
The summers are hot with low humidity. The Mile High City enjoys hours of sunshine and dry air penetrating from the Rocky Mountains. In mid-summer the average temperature is 74 degrees and 2.2 inches of precipitation is normal. But summer can bring inclement weather also, mostly in June.
Due to large warm masses of air from the Rockies and cooler air masses from the Great Plains, the temperatures can rise and fall immensely in just a few hours. However, usually the autumn temperatures are pleasant, but on the other hand the first snow of the season can fall as early as September!
Denver winters are mostly snowy and chilly. Although, as mentioned before, rapid temperature changes are not uncommon. The average temperature in January is 30 degrees. However arctic blasts can cause subzero recordings in at times.
We may conclude that Denver has a unique and great climate. There are plenty of sunny days which of course are ideal for outdoor activities. Low humidity in summer makes even the hottest day somewhat comfortable. So if you plan to visit Denver, keep in mind that when it comes to the weather, anything is possible!
