July Sets Record as Hottest Month in U.S. History, August Heat Persists
US · Published Aug 12, 2026
July 2026 has officially been recorded as the hottest month in U.S. history, with an average temperature of 76.9°F (24.9°C), according to NOAA. This surpasses previous records set in July 2012 and July
The extreme heat is attributed to human-caused climate change and the natural El Niño climate pattern, which has intensified global temperatures. NOAA reports that daytime maximum temperatures averaged 89.5°F (31.9°C), while nighttime minimums reached a record-breaking 64.2°F (17.9°C). The southern U.S. is expected to experience continued heat, with heat indices ranging from 105°F to 115°F (40.6°C to 46.1°C) and minimal nighttime cooling. Some local records, such as Pueblo, Colorado's 107°F (41.7°C), have already been broken. Experts warn that August could bring further extreme weather events.

Impact & Risks

The ongoing heat poses significant risks to public health, particularly in the Southeast and south-central U.S., where heat indices are forecasted to reach dangerous levels. Vulnerable populations, including the elderly, children, and those with pre-existing health conditions, are at heightened risk of heat-related illnesses. The lack of nighttime cooling exacerbates these risks, as it limits recovery from daytime heat. Additionally, the prolonged heat increases the likelihood of droughts, wildfires, and strain on energy resources. Experts link these conditions to climate change and warn of more frequent and severe heat events in the future.
