US Sees Hottest July on Record as Heat Wave Persists
July 2026 was the hottest month on record in the United States, with an average of 76.9°F—3.3°F above the 20th‑century average. Overnight temperatures drove the record, all 48 contiguous states posted above‑average temperatures, and Wyoming recorded its warmest July ever. Rainfall was generally below average and wildfire activity remained high; globally, July was among the warmest on record, aided by El Niño. The NOAA outlook for August suggests continued above‑average heat across the central and southern U.S. and elevated wildfire potential.
