Salt Lake City summers have grown hotter over the past five decades, a new report from Climate Central, a climate research group, shows.

Why it matters: Driven by climate change, heat stress is a major contributor of weather-related deaths that can intensify health conditions like cardiovascular disease, diabetes, mental health and asthma, according to the World Health Organization.

By the numbers: Average summer temperatures in Salt Lake City between 1970 and 2024 rose by nearly 6°F, per Climate Central.

Driving the news: Average summer temperatures during that span rose in 97% of the 242 cities analyzed in the report Axios' Alex Fitzpatrick writes.

Among those cities, summers are now 2.6°F hotter on average.
The analysis uses NOAA data and defines "summer" as June through August.

Zoom in: Last September, Salt Lake City tied its all-time hottest record when 107°F was recorded at the airport, FOX 13 reported.

The city approved $500,000 for shade cloths in up to five playgrounds the same year.

What's next: Summer 2025 is likely to be hotter than normal for much Utah, per the National Weather Service's seasonal outlook.
