Denver, Colorado, often referred to as the “Mile High City” due to its elevation of exactly one mile above sea level, boasts a unique climate that is a mix of both continental and high-altitude weather patterns. Whether you’re planning to move to Denver, visit for a few days, or are just curious about the city’s climate, we will provide you with all the details you need to know about Denver weather throughout the year.
Overview of Denver’s Climate
Location and Elevation
Denver is located on the western edge of the Great Plains, just east of the Rocky Mountains. This location plays a significant role in the city’s weather patterns. The elevation of Denver—5,280 feet above sea level—also contributes to its unique climate. The higher altitude results in thinner air, which can lead to more intense sun exposure and cooler temperatures, particularly at night.
Four Distinct Seasons
Denver experiences all four seasons, each with its own distinct weather characteristics. The city’s climate can be described as semi-arid, with relatively low humidity levels and plenty of sunshine year-round. Despite its reputation for snow, Denver receives an average of 300 days of sunshine annually, making it one of the sunniest cities in the United States.
Winter in Denver: December to February
Snowfall and Temperature
Winter in Denver is a season of contrasts. While the city does experience snowfall, it is not as harsh as one might expect. On average, Denver receives about 57 inches of snow per year. However, the snowfall is often light, and it melts quickly due to the strong Colorado sun. The city’s high altitude and dry climate prevent the snow from lingering for too long, so even after a heavy snowfall, it’s not uncommon to see clear roads and sidewalks within a day or two.
Temperatures during the winter months can vary widely. Daytime highs often reach into the 40s and 50s (°F), while nighttime lows can drop into the teens or even single digits. The combination of dry air and clear skies can lead to significant temperature drops at night, so it’s important to dress in layers when venturing out during the winter.
Winter Activities
Despite the chilly temperatures, winter is a vibrant season in Denver, offering plenty of outdoor activities. The nearby Rocky Mountains are a paradise for winter sports enthusiasts, with world-class skiing, snowboarding, and snowshoeing just a short drive away. In the city itself, residents and visitors can enjoy ice skating at outdoor rinks, holiday light displays, and cozying up in one of Denver’s many cafes or breweries.
Tips for Winter Weather
If you’re planning to visit Denver during the winter, be sure to pack warm clothing, including a heavy coat, gloves, and a hat. The high altitude and dry air can make the cold feel more intense, especially when the wind picks up. It’s also a good idea to stay hydrated, as the dry air can lead to dehydration more quickly than in lower, more humid climates.
Spring in Denver: March to May
Transitioning Weather Patterns
Spring in Denver is a season of transition, with weather that can be unpredictable. March is actually the snowiest month in Denver, often bringing heavy, wet snowstorms. However, by April and May, the snow begins to taper off, and temperatures start to rise.
Spring temperatures can fluctuate widely, with daytime highs ranging from the 50s to the 70s (°F). Nights are still chilly, with lows often in the 30s and 40s. As the season progresses, you’ll start to see more consistent warm weather, particularly in May.
Blossoming Nature
One of the most beautiful aspects of spring in Denver is the blossoming of nature. The city’s parks and gardens come alive with vibrant colors as flowers begin to bloom and trees start to bud. The Denver Botanic Gardens is a must-visit during this time of year, offering a stunning display of springtime flora.
Spring Activities
Spring is a great time to explore Denver’s outdoor spaces. Hiking and biking trails in the foothills of the Rockies are accessible once the snow melts, and the city’s numerous parks offer plenty of opportunities for picnics, outdoor sports, and leisurely strolls. Spring is also the start of the festival season in Denver, with events like the Denver March Powwow and Cinco de Mayo celebrations drawing large crowds.
Tips for Spring Weather
Spring weather in Denver can be unpredictable, so it’s important to be prepared for a variety of conditions. Pack layers that can be easily added or removed as temperatures change throughout the day. Also, be aware that late-season snowstorms are not uncommon, so keep an eye on the weather forecast and be prepared for sudden changes.
Summer in Denver: June to August
Warm and Sunny Days
Summer in Denver is warm, sunny, and relatively dry, making it a perfect time to enjoy the city’s outdoor activities. Daytime temperatures typically range from the 80s to the low 90s (°F), with occasional heatwaves pushing temperatures into the upper 90s or even low 100s. However, the low humidity levels make the heat more bearable than in more humid climates.
Nights are generally cool and comfortable, with temperatures dropping into the 50s and 60s. This makes summer evenings perfect for outdoor dining, concerts, and other nighttime activities.
Thunderstorms and Weather Patterns
One of the hallmarks of a Denver summer is the afternoon thunderstorm. These storms usually develop quickly and can bring brief periods of heavy rain, lightning, and even hail. However, they typically pass just as quickly as they arrive, and the sun often reappears within an hour or two.
These thunderstorms are most common in July and August, and while they can disrupt outdoor plans, they also help to cool down the temperature and provide much-needed moisture to the region.
Summer Activities
Summer is a time of endless outdoor possibilities in Denver. The city’s extensive trail system is perfect for hiking, biking, and running, while the nearby mountains offer more challenging terrain for adventurers. Water activities like kayaking, paddleboarding, and rafting are also popular in the area’s rivers and lakes.
Denver is also known for its vibrant summer festival scene. From the Denver PrideFest to the Colorado Dragon Boat Festival, there’s always something happening in the city. Music lovers can enjoy outdoor concerts at venues like Red Rocks Amphitheatre, which is considered one of the best outdoor concert venues in the world.
Tips for Summer Weather
To make the most of your summer in Denver, be sure to pack sunscreen, sunglasses, and a hat to protect yourself from the intense sun. It’s also a good idea to carry a light jacket or sweater for the cooler evenings. If you’re planning outdoor activities, try to schedule them for the morning or late afternoon to avoid the hottest part of the day.
Fall in Denver: September to November
Crisp Air and Fall Foliage
Fall in Denver is a season of breathtaking beauty. The air becomes crisp, the temperatures cool down, and the city’s trees put on a spectacular display of fall colors. Daytime highs in September are still warm, often reaching the 70s and 80s (°F), but by October and November, temperatures drop into the 50s and 60s. Nights are cool and can dip into the 30s, particularly in November.
The fall foliage in and around Denver is a sight to behold. The city’s many parks, including Washington Park and City Park, are ablaze with the colors of autumn, making them perfect spots for a leisurely walk or a photoshoot. Just outside the city, the Rocky Mountains offer even more stunning fall scenery, with golden aspen trees lining the hillsides.
Transition to Winter
As fall progresses, Denver begins to see the first signs of winter. Snowfall can occur as early as October, though it’s typically light and doesn’t accumulate significantly until later in the season. November often brings more consistent cold weather and the occasional early snowstorm.
Fall Activities
Fall is a fantastic time to explore Denver’s natural beauty. The cooler temperatures make it ideal for hiking, and the fall colors add an extra layer of enjoyment to outdoor activities. The Denver area is also known for its harvest festivals, pumpkin patches, and corn mazes, making it a great time for family-friendly outings.
For sports fans, fall means the start of football season, and Denver is home to the NFL’s Denver Broncos. Attending a game at Empower Field at Mile High is a quintessential Denver experience, especially as the crisp fall air adds to the excitement of the game.
Tips for Fall Weather
Fall weather in Denver can change quickly, so it’s wise to dress in layers. Mornings and evenings can be quite chilly, while afternoons are often warm. Be prepared for the occasional early snowfall by having a warm coat and boots on hand, especially in late October and November.
The Impact of Altitude on Denver’s Weather
High Altitude and Its Effects
Denver’s elevation of 5,280 feet above sea level has a significant impact on its weather and overall climate. The high altitude leads to thinner air, which means that the atmosphere absorbs and retains less heat. As a result, temperatures can drop quickly after sunset, even during the summer months.
The thinner air also means that the sun’s rays are more intense in Denver. This can lead to quicker sunburns, so it’s important to wear sunscreen and protective clothing, even on cloudy days. Additionally, the high altitude can cause some people to experience altitude sickness, particularly if they are not accustomed to it. Symptoms include headaches, dizziness, and shortness of breath, but these typically subside as the body adjusts to the altitude.
Altitude and Precipitation
Denver’s altitude also affects the type and amount of precipitation the city receives. Snowfall in Denver tends to be lighter and fluffier than in lower-elevation areas because the dry air at higher altitudes doesn’t hold as much moisture. Rainfall is also less frequent in Denver compared to more humid regions, but when it does rain, it often comes in the form of brief but intense showers, particularly during the summer.
Tips for Adjusting to the Altitude
If you’re visiting Denver from a lower elevation, it’s important to take some time to acclimate to the altitude. Drink plenty of water to stay hydrated, avoid strenuous activities for the first day or two, and be mindful of how your body is feeling. If you experience severe symptoms of altitude sickness, such as difficulty breathing, seek medical attention.
