Maryland officials reported 61 heat-related deaths during the 2026 season, marking the highest number of fatalities in the state's recorded history. Emergency medical services responded to 1,657 calls for heat-related illnesses as temperatures reached dangerous levels.
Why it matters
Climate change is driving longer, more intense heat waves that prevent overnight recovery for the human body. Many residents face increased risk because they lack air conditioning or cannot afford the utility costs required to run cooling systems.
Maryland recorded 61 hyperthermia deaths in 2026, surpassing the 2012 record of 42. Additionally, emergency services logged 1,657 calls for heat illness, while 1,603 patients sought emergency department or urgent care visits.
The details
Indoor deaths accounted for 48% of total fatalities, while 26% occurred outdoors and 26% happened in vehicles. Among the victims, 62% were aged 65 or older, 26% were aged 45 to 64, and 10% were aged 18 to 44, with 41 deaths clustered between late June and early July.

Seasonal Patterns
This year's record-breaking death toll marks a significant departure from the previous peak established by the 2012 Maryland heat-related fatality record. The trend highlights a shift toward more frequent, intense heat waves that now exceed historical state averages.
Residents should ensure access to air conditioning and utilize public cooling resources during high-temperature alerts. Those in low-income areas without sufficient greenspace or cooling infrastructure are encouraged to monitor state heat advisories closely.
The takeaway
The high percentage of deaths occurring indoors emphasizes the critical need for affordable cooling access and improved infrastructure. Protecting vulnerable populations, especially those aged 65 and older, remains a primary challenge as regional temperatures continue to rise.
