HOT, Like It or Not
The average U.S. summer temperature was 73.8 degrees, 2.2 degrees above the 20th-century average, NOAA said.
NOAA announced on September 9 that the contiguous United States experienced its hottest summer on record, with the 2026 meteorological season surpassing the previous 132-year record by 0.4 degrees.
The average temperature reached 76.9 degrees, measuring 3.3 degrees above the 20th-century average. Dangerous heat waves impacted the East Coast and Midwest, driving sustained high temperatures throughout the season.
Four states, including Colorado and Utah, broke their individual all-time warmest summer records. The nation set 17 daily heat records during the period, driven by a persistent heat dome.
June and August were the warmest such months on record for the contiguous United States, while July also ranked as the hottest month. These three consecutive months drove the seasonal average.
This record-breaking summer reflects a long-term warming trend in the contiguous United States. NOAA data indicates the 2026 average exceeds previous highs from 1936 and 2021 by 0.4 degrees, underscoring persistent climate shifts.
The debates on how to name the climate crisis and its effects have ceased to be renewed in recent decades, both to alert the public, but also to describe increasingly intense and extreme phenomena.
