Summer 2026 Declared Hottest on Record by NOAA
US · Published Sep 17, 2026
The National Oceanic and Atmospheric Administration (NOAA) has confirmed that summer 2026 is the hottest on record in the United States, surpassing previous records set in 2021 and
The average temperature across the continental U.S. was 75.6°F (24.2°C), with daytime highs averaging 88.6°F (31.4°C). The southern and western regions experienced the most intense heat, while the Midwest, Great Lakes, and Northeast saw near or slightly above-average temperatures. Arizona endured its second-hottest summer, with an average of 97°F (36.1°C) and 39 days exceeding 110°F (43.3°C). Nearly 60% of the country is also facing drought conditions, exacerbating the heat. NOAA attributes the extreme temperatures to persistent heat domes, drought, and a skewed jet stream pattern that trapped heat across the U.S.

Impact & Risks

The record-breaking heat has had widespread impacts, including increased utility bills, with some areas experiencing up to a 10% rise. Drought conditions have affected nearly 60% of the U.S., intensifying the heat and straining water resources. The heat has also contributed to a rise in heat-related deaths, with global figures showing an 85% increase in such fatalities since 2000. The ongoing El Niño weather pattern is expected to prolong unseasonably warm conditions into autumn and winter, potentially leading to more extreme weather events. These conditions pose risks to public health, agriculture, and infrastructure.
