Maricopa County has recorded a decrease in heat-related deaths for the first time in a decade, with 602 confirmed fatalities in 2024—down from 645 the previous year, despite enduring its hottest summer yet, according to the Maricopa County Department of Public Health (MCDPH). While this represents a step forward, Thomas Galvin, Chairman of the Maricopa County Board of Supervisors, emphasized the importance of ongoing education on the dangers of heat, remarking, "Each death is a preventable tragedy." In a preliminary report released by Maricopa.gov, the MCDPH outlined these figures along with their initiatives to combat the problem.
Within the 2024 season, Phoenix faced a grueling 113 consecutive days of temperatures at or above 100°F. The impact of extreme heat continued to disproportionately affect the most vulnerable—people experiencing homelessness, older adults, and substance users. A staggering 89% of heat-related deaths that involved substances were linked to stimulants. Dr. Nick Staab, MCDPH's chief medical officer, highlighted that "heat is a force multiplier for many underlying health conditions," and made clear the dire need to effectively address this magnified risk.
The report also brought to light that a significant portion of these tragedies could potentially be avoided. It was found that 88% of indoor heat deaths had an air conditioning unit present, yet a troubling 70% of those were non-functional. It's crucial to underscore that the heat risk was rated as moderate on days accounting for more than half of all heat deaths in 2024, which indicates a lack of public awareness or preparedness for moderate-risk conditions.
In response to these challenges, MCDPH is set to enhance prevention and response measures throughout 2025. Their approach includes intergovernmental agreements to extend the hours and days of heat relief sites, collaboration with community-based organizations for water distribution and cooling center support, and increased help for residents to better access these resources. To better aid the community, many centers are planning to remain open until at least 7 pm and to operate on weekends. Moreover, public awareness campaigns will be bolstered, aiming to inform residents of how to utilize heat relief resources, such as through the 2-1-1 hotline, which also provides transportation to cooling centers and emergency repair services for air conditioners. Dr. Staab encourages community members "to take proactive steps," such as staying hydrated and checking on vulnerable neighbors.
The MCDPH anticipates that their final heat deaths report for 2024, which will provide total counts and further data, will be released in spring 2025. This forthcoming report will be accessible on the Maricopa County website, offering more insights into heat-related illnesses and data for those interested in monitoring the county's progress in this ongoing fight against heat-related fatalities.
