Temperatures were above average across much of the Mountain West and much above average across the eastern U.S., while most of the Plains saw near-average conditions. Virginia and West Virginia each tied their warmest July on record, while all Atlantic coastal states from Florida to Delaware saw temperatures that ranked among their four warmest. Warmth during the overnight hours was especially notable, with record-warm average minimum temperatures in 12 states spanning the Southeast, Mid-Atlantic and Ohio Valley.

Alaska’s average temperature for July was 55.3°F, 2.6°F above the 1925–2000 average, ranking in the warmest third of the 101-year record. Much of the state, particularly the North Slope, saw above-average temperatures. Hawaiʻi’s average temperature was 69.3°F, 0.5°F above the 1991–2020 average, placing it in the middle third of the 35-year record.
