When is the Best Time to Visit Denver?

The best time to visit Denver is during its off-peak months of April, May, September, and October. The weather is mild, and since it’s shoulder season, there will be fewer visitors at top attractions, lower rates for accommodations, and cheaper airfare versus the high seasons of summer and winter.

Denver is a year-round destination that lures travelers in every single season. The best time to visit Denver depends on you and what you’re looking to do during your vacation. We break it down in a few different ways below.

Best Time to Visit Denver: For Optimal Weather

Optimal weather in Denver truly depends on what you’d like to do with your time.

Spring: The city blooms, literally and figuratively, starting again in the spring. Spend time outside hiking, enjoying the Denver Botanic Gardens or going to Coors Field to catch a Major League Baseball game.

Summer: Denver enjoys a mild, dry summer. Humidity is low and the daily average temperature is around the mid-to-high 80s. It’s a wonderful time to be outdoors at night, whether you’re camping under the stars or enjoying a live concert at Red Rocks Amphitheatre.

Fall: Leaf peepers can enjoy autumn colors around Denver from mid-September through mid-November. There are multiple climate zones within a 2-hour drive of the city, which affords travelers a longer period of time to enjoy the vibrant yellows, oranges, and reds that make this season a special one around Denver.

Winter: The mountains surrounding Denver are some of the top destinations for winter activities. Hit the slopes just an hour or two outside the city at Copper Mountain, Keystone Resort, Eldora Mountain, Winter Park Resort and more.

Best Time to Visit Denver: For Less Crowds

As previously mentioned, summer is quite mild in and around Denver. That makes June through August a peak time for visitors (you can see in the graph above that flight prices follow suit).

Ski season, from November through March, is also a popular time of year for the Denver area.

To avoid the largest crowds, travel to Denver during the off-peak months of April, May, September, and October. You’ll encounter fewer tourists, and your wallet will thank you, too, with cheaper accommodations and flights (more on that below).

Best Time to Visit Denver: For Cheap Flights

We noted earlier that January is the cheapest month to fly to Denver. You’re more likely to find airfare that is 25% cheaper than the average yearly flight price! That’s good news for snow birds, but what if parka weather isn’t your thing?

April, September, and October are your next three best options for lower airfare. You may pay around 20% more than if you travel in January, but you’ll bypass the crowds, which could mean lower accommodation prices too. Plus, you’ll still pay about 25% less for airfare than during the peak travel month of July.
