July 2026 Becomes Hottest Month Ever Recorded in US History

July 2026 has officially become the hottest month ever recorded across the contiguous United States, according to new data released by the National Oceanic and Atmospheric Administration NOAA. The record-breaking heat capped a summer of intense temperatures across the country, with prolonged heat domes pushing temperatures to extraordinary levels from the East Coast through the Plains and into the Southwest. NOAA’s national climate records date back to 1895, making the latest reading part of more than 130 years of temperature observations According to NOAA’s National Centers for Environmental Information, the average temperature across the contiguous United States in July was approximately 76.9°F 24.9°C. That surpassed the previous record of 76.77°F 24.87°C, set in July 1936, during one of the most notorious heatwaves in US history. The new record means July 2026 was not simply the hottest July on record but the warmest single month of any kind recorded across the contiguous United States.

Much of the extreme heat was associated with persistent heat domes areas of high atmospheric pressure that trap hot air near the surface and prevent cooler air from moving in. The pattern produced repeated and prolonged periods of dangerous heat across large sections of the country. Temperatures soared across the East Coast, Midwest, Great Plains and Southwest, with many communities experiencing consecutive days of unusually high temperatures. Unlike some previous record-breaking months, the July heat was widespread. NOAA reported that every state in the contiguous US experienced above-average temperatures during the month. The extreme conditions affected both major cities and rural communities.The Southwest experienced particularly intense heat, while parts of the Plains and eastern United States also endured prolonged periods of temperatures well above normal.

The combination of high daytime temperatures and unusually warm nights increased the health risks because people had fewer opportunities to cool down after sunset. Heatwaves can be especially dangerous for older people, young children, outdoor workers and people with limited access to cooling.

The latest record comes after an exceptionally warm start to 2026.

March 2026 was already the warmest March on record for the contiguous United States, according to NOAA, with the national average temperature about 9.4°F above the 20th-century average.

The succession of unusually warm months has added to concerns about the increasing frequency and intensity of extreme heat events. Scientists have linked the broader long-term warming trend primarily to human-caused climate change, while natural climate patterns can influence temperatures from year to year. The record heat may not be over. NOAA’s Climate Prediction Center is forecasting above-average temperatures across much of the continental United States through August, meaning many communities could continue experiencing unusually hot conditions.

Authorities are urging residents to take extreme heat seriously by staying hydrated, limiting strenuous outdoor activity during the hottest parts of the day and checking on vulnerable family members and neighbours. The July record is now another major marker in the United States’ rapidly changing temperature history and a warning that extreme heat is becoming an increasingly important publichealth and climate challenge.
