Extreme Heat
What is an "Urban Heat Island"
Urban Heat Islands are areas with less shade or tree cover and more hard surfaces like concrete, asphalt and glass that concentrate heat and raise air and surface temperatures. These areas can be up to 7 degrees Fahrenheit hotter in the daytime and up to 5 degrees hotter at night than shady areas.

Heat Mapping Campaign
Oklahoma City was selected(PDF, 815KB) as one of 18 communities worldwide for NOAA's Urban Heat Island Mapping Campaign in 2023. The project involved help from several community partners and "street scientists" who volunteered to measure air temperatures and air quality conditions.
The image above shows temperature data points gathered in the morning, afternoon and evening of Aug. 12, 2023, during our Urban Heat Island Mapping Campaign.
Heat Health Resource Hub
The resource center explains what heat health is for OKC residents. It also shows how the City can prioritize solutions, like where to put new Cooling Centers or where to plant trees.

Athletes: are you at high risk?
Athletes are at risk of heat illness when they're outside during high temperatures, especially if they wear protective gear that traps heat. Children who play sports are also at high risk, because their bodies can't cool down as quickly as a healthy adult.
