Descriptive Analysis: Extreme Heat Days

The Centers for Disease Control and Prevention (CDC) define extreme heat as summertime temperatures that are much hotter and/or humid than average. The National Weather Service uses the heat index to measure the combination of temperature and humidity. It lets you know how hot it feels outside better than temperature alone. In Michigan, a heat index value of 90^oF is used as an indicator for extreme heat.

Figure 1. Annual number of extreme heat days (Daily Heat Index above 90^oF) for 1979 to 2023 for Michigan’s five most populous counties. Explore the MiTracking extreme heat query (select Genesee, Kent, Macomb, Oakland and Wayne counties in the Chart results tab).

Figure 1 illustrates the annual number of extreme heat days (Daily Heat Index above 90^oF) for 1979 to 2023 for Michigan’s five most populous counties: Genesee, Kent, Macomb, Oakland and Wayne. Wayne County consistently had more extreme heat days per year than the other counties. In the most recent years, the annual number of extreme heat days has decreased. For this period, there has been an increasing trend (dotted line) in the number of extreme heat days for these five counties.

Extreme heat days can affect health and contribute to heat-related illnesses. Even short periods of high temperatures can cause serious, and sometimes life-threatening, health problems like heat exhaustion and heat stroke. Heat is the leading cause of extreme weather-related deaths in the United States. Everyone is at risk of heat-related illness due to extreme heat days, but some are more than others. Remember to protect yourself, your family and your pets by staying cool, staying hydrated and staying informed!

New Resources: Climate Changes MI Health (CCMIH) - Extreme Heat and Precipitation

CCMIH Extreme Heat and Extreme Precipitation infographics are now available. CCMIH is a collaboration between the MiTracking program and the MICHAP. The CCMIH series connects how climate change affects health while exploring environmental and health data with MiTracking. CCMIH stresses how helping to reduce climate change and adapting to its impacts could be an opportunity to improve health.

About the MiTracking Program

MiTracking gathers existing Michigan environmental, health and population data, providing them all in one online location. Data is displayed in tables, charts and maps. You can download, save and print these data visualizations.  

Everyone from community members to public health professionals to students, can run data searches. With these tools, MiTracking can help all Michiganders explore how the environment may impact health.

The MiTracking Program is part of CDC's National Environmental Public Health Tracking Program (Tracking Program). MiTracking is a Michigan Department of Health and Human Services (MDHHS) Division of Environmental Health (DEH) program. You can find MiTracking at Michigan.gov/MiTracking.
