Weather in Denver: What to Wear & Expect During Your Stay
The weather in Denver is sunny and beautiful most of the year. We have all four seasons. The sun shines almost 300 days a year, with some rainy and snowy days.
The snow usually starts to fall sometime in late October. It will last until around March or April. We typically get around 60 inches of snow yearly, but it doesn’t accumulate much as it usually melts away quickly from the sun.
Some years, you might see snow as early as September or as late as May. During my first year here, it snowed almost an inch the week before Memorial Day Weekend.
The summers are warm, with just a few inches of rain each month. On the days it rains, the clouds usually roll in over the mountains late afternoon and clear up within an hour or two. Before and after the rain, you will find clear blue skies.
The Denver, CO, weather is warmest in July, with the average highs in the mid-80s. The coldest month is January, with average highs in the mid-40s and lows around 15 daily.

Spring in Denver
The springtime in Denver is gorgeous, with the weather forecast often including snowy and rainy days. Most of the time, though, you will find clear blue skies.
March is one of our snowier months, but it’s mostly cleared off when spring officially hits on the 20th. Temperatures in the spring range from around the mid-50s in March to 80 in early June.
Early spring is a great time to head up to the mountains for some last-minute skiing. Spring is also when the outdoor festivals begin.
In the spring, you will find fewer crowds around town, so it’s easy to see quite a bit during your stay.

Stay hydrated, as the altitude and intense sun can dehydrate you quickly.

Ski season typically starts anywhere from late October to mid-December. The mountain ski resorts are always racing to be the first to open, and most try to open by Thanksgiving Weekend (as long as Mother Nature cooperates).
