Risk Snapshot

Climate Change Hazard Ratings for Memphis, TN

Ratings represent risk relative to North America. 100 is the highest risk for the hazard and 1 is the lowest, but does not indicate no risk. Flood and fire are rated based on the buildings in Memphis exposed to these hazards. See hazard sections below and check your address for details.

People in Memphis, TN are especially likely to experience increased risks from heat, precipitation, and fire.

Not only is Memphis known for its rich Jazz, Blues and Rock-n-Roll music culture, but it is also the largest city in Tennessee. Heat waves pose a threat to Memphis, with the urban heat island effect increasing the danger to people within its city landscape. There is also some risk of wildfire for a significant fraction of buildings in Memphis.

Heat risk in Memphis, TN

The number of the hottest days in Memphis is projected to keep increasing.

In a typical year around 1990, people in Memphis, TN experienced about 7 days above 96.9ºF in a year. By 2050, people in Memphis are projected to experience an average of about 51 days per year over 96.9ºF.

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.

Precipitation risk in Memphis, TN

The share of precipitation during the biggest downpours in Memphis is projected to increase.

A downpour for Memphis, TN is a two-day rainfall total over 1.2 inches. Around 1990, about 42.0% of precipitation fell during these downpours. In 2050, this is projected to be about 46.0%. The annual precipitation in Memphis, TN is projected to increase from about 51.3" to about 53.5".

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.

Fire risk in Memphis, TN

The risk on the most dangerous fire weather days in Memphis is moderate. The number of these days per year is expected to increase through 2050.

Of 362 census tracts in Memphis, TN, there are 302 where more than a quarter of buildings have significant fire risk, and 269 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.

Drought risk in Memphis, TN

The average water stress in Memphis is projected to be about the same around 2050 as around 2015.

The Lower Mississippi-Memphis watershed, which contains Memphis, TN, has experienced 567 weeks (47% of weeks) since 2000 with some of its area in drought of any level, and 61 weeks (5% of weeks) since 2000 with some of its area in Extreme or Exceptional drought. Source: National Drought Monitor.

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.

Flood risk in Memphis, TN

Buildings at risk in Memphis average about a 33% chance of a flood about 10.0 inches deep over 30 years.

Of 362 census tracts in Memphis, TN, there are 4 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.

How can we limit climate change and live in a transforming world?

The projections on this page describe a future that we still have a chance to avoid. To keep average global warming below 1.5ºC—the goal agreed on in the 2015 Paris Climate Accords—we need to act rapidly to drastically reduce greenhouse gas emissions.

Understand Risks

The risks presented on this page reflect modeled averages for Memphis, TN under one projected emissions scenario and can vary for individual properties. To find out more, check a specific address and request a report describing risks to your property and in your area.

Reduce Emissions

The latest Intergovernmental Panel on Climate Change report states: “If global emissions continue at current rates, the remaining carbon budget for keeping warming to 1.5ºC will likely be exhausted before 2030.” This remaining carbon budget is about the same amount as total global emissions 2010-2019.

In the United States, the largest share of greenhouse gas emissions comes from transportation (about 30%). Globally the vast majority of transportation-related emissions come from cars and trucks, followed by shipping and air travel, which is growing quickly.

Compared to the rest of the world, the U.S. uses twice the average share of emissions for its buildings (including heating and cooling).

Reducing emissions is necessary and possible across the globe and in every part of our society. Learn more with the Not Too Late project and the Project Drawdown introduction to climate solutions.

Green infrastructure is a category of nature-based solutions for managing increasing precipitation. Find resources for individuals and municipalities through the EPA Soak Up the Rain initiative.

Planting trees and vegetation helps reduce extreme heat in urban environments. Cool pavements can also help. Search the Heat Island Community Actions Database to see what some municipalities have been doing to reduce extreme heat risk.
