Lower 48 Contiguous United States temperature average compared to 1991-2020 normal was +1.35°F from PRISM (Oregon State) for July 2023 with southern Arizona including Phoenix at least 7°F hotter than normal. Western Texas including El Paso experienced very hot conditions. However, the central Plains were much cooler than normal matching up with areas of cloud cover and above normal precipitation. The winner was New England with boatloads of rainfall during July.
