People in Denver, CO are especially likely to experience increased risks from heat, drought, and flood.

Denver, known for its high-altitude location at the edge of the Rocky Mountains, has a semiarid, relatively mild climate, with many sunny days per year. Air pollution can be a significant problem in Denver due to its topography, with cars, trucks, and coal-fired power plants among the contributing sources of ozone and particulate pollution. As climate change brings increased heat and drought risks, people in Denver are also especially vulnerable to poor air quality during wildfires.

In a typical year around 1990, people in Denver, CO experienced about 7 days above 94.2ºF in a year. By 2050, people in Denver are projected to experience an average of about 43 days per year over 94.2ºF.

Climate change is increasing the frequency and intensity of heat waves, even in places with cooler average temperatures. See more information on heat risk. Everyone can take steps to reduce their risks from extreme heat.

The Middle South Platte-Cherry Creek watershed, which contains Denver, CO, has experienced 838 weeks (70% of weeks) since 2000 with some of its area in drought of any level, and 147 weeks (12% of weeks) since 2000 with some of its area in Extreme or Exceptional drought.

Climate change is increasing the risk of drought. Water stress (the ratio of water demand to supply) depends on how water utilities source water and their plans to adapt to climate change. Property owners can also take steps to reduce their risks from drought.

Of 453 census tracts in Denver, CO, there are 21 where more than half of buildings have significant risk from surface (pluvial) flooding and riverine (fluvial) flooding. Property owners can check a specific address for flood risk including FEMA flood zone, then take steps to reduce their vulnerability to flooding damage.

Climate change is increasing inland and coastal flooding risk due to sea level rise and increasing chances of extreme precipitation. See more information on flooding risk.

A downpour for Denver, CO is a two-day rainfall total over 0.4 inches. Around 1990, about 46.0% of precipitation fell during these downpours. In 2050, this is projected to be about 50.0%. The annual precipitation in Denver, CO is projected to increase from about 15.3" to about 16.1".

Extreme precipitation in any form can pose significant risks. Climate change is increasing the potential for extreme rainfall or snowfall because warmer air can hold more water vapor. See more information on storm risk. Property owners can take steps to reduce their risks from extreme precipitation.

Of 453 census tracts in Denver, CO, there are 195 where more than a quarter of buildings have significant fire risk, and 135 where more than half of buildings have significant fire risk. Property owners can take steps to mitigate their risks from wildfires.

Fire risk depends on proximity to vegation: densely developed urban areas have a much lower risk of burning than areas adjacent to wildland. Climate change increases risks from wildfire by creating hotter, drier conditions for fires to spread. ClimateCheck ratings of fire risk are based on projected weather conditions and U.S. Forest Service models simulating fire behavior.
