Record July Heatwaves, Droughts Persist in U.S., UK

July 2025 brought record-breaking and extreme heat to several regions, with Memphis experiencing its third hottest July on record and prolonged heat warnings. The UK recorded its fifth warmest July, continuing a six-month trend of above-average temperatures and leading to official drought declarations in multiple areas. In contrast, Sioux Falls, South Dakota, saw a rare shift to cooler temperatures as August began, which is unusual according to historical data. As August starts, daylight hours are continuing to shorten, signaling the gradual transition from summer toward autumn. Despite some regional relief, the persistence of heatwaves and drought remains a concern in both the U.S. and the UK.
