How Elevation Impacts Arvada’s Climate

At 5,300 feet above sea level, Arvada’s elevation plays a major role in its cooler and drier climate compared to nearby Denver:

  • Cooler temperatures: For every 1,000 foot rise in elevation, temperature drops 3-5°F. This accounts for Arvada’s temperatures being 5-10°F cooler than Denver on average.
  • Less moisture: Moisture decreases about 15% for every 1,000 feet gained in elevation. Less moisture means less humidity and precipitation.
  • More sunshine: Higher elevations receive more direct sunlight due to less atmosphere and scattering. Arvada sees 5-10% more sunny days than Denver annually.
  • Briefer growing season: Higher elevations have a shorter frost-free growing season. Arvada’s season is about 2 weeks shorter than Denver’s.
  • Increased snow: Arvada gets 10-15 more inches of snowfall on average compared to Denver as a result of the elevation.
  • Enhanced UV: With less atmosphere at higher elevations, UV index ratings can be more extreme. More diligent sun protection is needed.

How Continental Location and Topography Impact Climate

In addition to elevation, Arvada’s climate is shaped by:

  • Distance from mountains: Arvada’s location 10-15 miles east of the Front Range of the Rockies blocks some precipitation and moisture. This rain shadow effect enhances its drier climate.
  • Flat, open terrain: With an average elevation change of just 500 feet across the city, Arvada lacks major terrain barriers that would influence local weather patterns. This allows frontal systems to pass through easily.
  • Latitudinal position: Sitting at 39-40°N places Arvada in the mid-latitudes, far from moderating coastal effects. This continental location contributes to variable weather and distinct seasons.
  • Rain shadow effect: As Pacific storms move over the Rockies, the mountains wring moisture out through orographic lift on the windward side. This leaves the leeward side (including Arvada) noticeably drier.
  • Chinook winds: These periodic warm, dry gusts descending the eastern Rockies slopes can rapidly boost temperatures, sometimes 40-60°F in hours. This moderates Arvada’s winter cold.

Typical Annual Weather Cycle

Arvada’s climate follows a classic seasonal weather cycle each year:


December-February bring consistent snowfall and the coldest temps. Bitter wind chills occur with lows below zero. Storm tracks bring frequent snow events. Skies are often cloudy.


March-May see a gradual warm up along with bone-dry conditions. Late snows give way to sunny, mild days and wildflower blooms. Temperature swings are common.


June-August are hot and extremely dry. Monsoon moisture sparks thunderstorms in the afternoons. Temperatures routinely top 90°F, with long stretches above 100°F.


September-November cools off quickly with frost by October. Snow becomes likely by late fall. The first freeze ends the growing season. Daylight hours rapidly diminish.

Historical Weather Events

Here are some exceptional historical weather events that have impacted Arvada:

  • 2013 Floods: A stalled weather system dumped over a foot of rain across the Front Range in September 2013. Catastrophic flooding ensued, with 4 county flood disasters declared. Rivers swelled to all-time highs.
  • March 2003 Blizzard: A massive 3-day blizzard crippled the Front Range urban corridor with over 5 feet of snow. Arvada recorded 28 inches. Drifts reached 16 feet. Interstates closed for days.
  • 1965 Floods: In June 1965, up to 14 inches of rain fell over 2 days, overwhelming Denver-area drainage systems. Extensive flooding damaged homes and infrastructure across Arvada and environs.
  • Halloween Blizzard 1991: One of Colorado’s notorious blizzard events buried Arvada under 22 inches of October snow. Trees snapped under the weight of the heavy, wet snow. Power was knocked out for a week in spots.
  • Christmas Eve Blizzard 1982: What began as rain transitioned to heavy snow on December 24, 1982. Denver set a new one-day snowfall record of 20.2 inches. Arvada also measured over 2 feet of snow.
