Wake County faces dangerous heat and smoke as air quality worsens

Wake County kept cooling stations open daily through at least Monday, July 20, as a Code Orange air-quality day layered wildfire smoke on top of stifling heat and humidity. The combination pushed the risk well beyond discomfort for older adults, young children in summer camps, outdoor workers, and people with asthma, heart disease or chronic respiratory illness.

Heat can bring dehydration, fatigue, cramps and heat exhaustion. Poor air quality can irritate lungs, worsen chronic illness and make exercise or outdoor work risky, especially for people who do not have reliable air conditioning or transportation to get out of the heat.

The Triangle was dealing with hazardous air quality from smoke drifting south from Canadian wildfires and high ozone levels trapped by stagnant heat, with Wake County and Durham both under Code Orange alerts. Wildfire smoke can travel hundreds of miles and make air unhealthy even when the fire is far away.

State air-quality forecasts are built to catch that overlap. The North Carolina Department of Environmental Quality issues fine-particulate forecasts year-round and ozone forecasts from March through October, and its climate and air-quality portal updates discussions for the next three days. A July 17, 2023 DEQ release forecast unhealthy air in North Carolina that week because of Canadian wildfires.

The danger rises when smoke and summer heat hit at the same time. On July 16, 2026, the American Heart Association said wildfire smoke exposure can cause heart problems or worsen existing ones, especially when paired with summer temperatures. Poor air quality can aggravate asthma, heart disease and lung disease.

Wake County has dense urban neighborhoods, fast-growing suburbs, construction sites, summer camps and commuter traffic, and many residents spend long stretches outside, often with little control over the air they breathe.
