July was the hottest month on record for the contiguous U.S., per new federal data dating back to 1895.
By the numbers: Last month's average temperature was 76.89°F, topping the 76.77°F mark set in July 1936.
That's 3.3°F warmer than the 1901-2000 average.
What they're saying: "Above-average temperatures covered the entire [contiguous U.S.], with all states ranking in the warmest third of their July temperature records and none ranking near or below average," NOAA's National Centers for Environmental Information said in its monthly report.
The big picture: July featured a series of "heat domes" across the country that trapped warm air beneath them, fueling several extreme heat events.
Researchers have found that climate change is making extreme heat events more common and more intense — but they're also linked to phenomena and patterns like El Niño.
What we're watching: NOAA's Climate Prediction Center is calling for an elevated chance of above-average temperatures for most of the continental U.S. through August.
It's also possible that 2026 will set a new record for the hottest year globally.
