Factors Influencing Snowfall in Colorado

The Role of Elevation

Colorado is a state of varying altitudes, and higher elevations like the Rocky Mountains can receive significant snowfall. In simple terms, the higher you go, the more snow you’ll find.

The Impact of La Niña and El Niño

La Niña and El Niño weather patterns influence how much snow Colorado receives. La Niña generally brings more snow to the northern and central mountains, while El Niño often results in drier conditions but can sometimes increase snowfall in the southern part of the state.

Proximity to Moisture Sources like the Gulf of Mexico

Moisture from the Gulf of Mexico often fuels Colorado’s snowfall, especially in the eastern plains and Front Range. The journey of this moisture and how it combines with local weather systems is crucial for big snow events.

A Month-by-Month Breakdown of Colorado Snowfall

In Colorado, the snow season unfolds in a dramatic, month-by-month spectacle that varies by region. October kickstarts the snowfall, especially in higher elevations like Estes Park and Aspen. Come November, the chill really sets in; mountainous areas can see between 8 to 16 inches of snow on average, signaling the transition from fall’s colorful foliage to winter landscapes. December and January are the blockbuster months, with December seeing up to 20 inches in the mountains and hotspots like Vail and Breckenridge becoming winter wonderlands. January often outdoes December, with snowfall in mountain areas that can soar up to 24 inches, making it one of the snowiest months.

February keeps the momentum going with a consistent but slightly lighter snowfall, averaging between 18 to 22 inches in the high altitudes. March, however, is a transitional month. While early March usually continues the snowy trend, the latter part of the month starts showing the first signs of spring. April and May signal the winding down of the snow season. April typically has decreasing snowfall, but it’s not unusual to witness a late-season snowstorm. By May, the chance of snowfall becomes less predictable and is generally confined to higher elevations. If it does snow, it usually melts quickly, making way for spring’s full bloom.

Snowfall Across Colorado

The Rocky Mountains and the San Juan Mountains are the snowiest places in Colorado, sometimes receiving over 200 inches in a season

The plains and lower-altitude areas like Denver and Boulder get less snow and are subject to more fluctuating conditions. Unique weather pockets, known as microclimates, can cause localized heavy snowfall, like the “Buffalo Pass” near Steamboat Springs

Unforgettable Colorado Snow Events

The Blizzard of 2003

In March 2003, Colorado experienced one of its most memorable blizzards. The storm dumped as much as 31 inches of snow in the Denver metro area, shutting down the city for days. The Rocky Mountains saw even more—up to 7 feet in some areas! The event serves as a reminder of the power and unpredictability of Colorado winters.

The 1982 “Christmas Eve Storm”

Talk about a white Christmas! In 1982, a storm began on Christmas Eve that would dump more than two feet of snow in places like Denver. Airports closed, families were stuck at home, and it turned out to be one of the most iconic weather events in Colorado history.

Snowmageddon 2015

In late November 2015, Colorado faced another unforgettable winter storm, nicknamed “Snowmageddon.” Some areas got as much as 16 inches of snow, causing massive travel disruptions right before Thanksgiving.

Skiing and Winter Sports: Timing and Locations

Most ski resorts in Colorado aim to open by late November and generally close by mid-April. Some resorts located at higher elevations like Arapahoe Basin can remain open until June!

If you’re looking for fresh powder, January and February are your best bets. These months usually have the most consistent snowfall and the fluffiest snow.

If you want to avoid the crowds, consider going in late November or early December, and again in late April. The snow might not be as abundant, but you’ll have more of the mountain to yourself.

Practical Tips for Colorado Snow Season

  1. Proper attire includes moisture-wicking base layers, an insulating middle layer (like fleece), and a waterproof outer layer. Don’t forget a good pair of gloves, a warm hat, and snow boots!
  2. Always check road conditions before you head out. Carrying chains, a shovel, and emergency supplies is highly recommended, especially if you’re heading to the mountains.
  3. If you’re going into backcountry areas, it’s essential to have avalanche safety training and gear. Always check the avalanche forecasts and make sure you know what to do in case of an emergency.
