Temperature
June U.S. Mean Temperature Departures from Average Map
The average temperature for the contiguous U.S. (CONUS) in June 2025 was 71.2°F, 2.8°F above the 20th-century average, and ranked seventh warmest in the 131-year record. Temperatures were above average across most of the Lower 48, with much-above-average warmth affecting large areas of the western third of the country, along with parts of the Florida Peninsula, Mid-Atlantic, Northeast and Great Lakes regions. Rhode Island saw its second-warmest June on record and its warmest for nighttime minimum temperatures, which were 5.8°F above average.
Alaska’s average temperature for June was 50.8°F, 1.6°F above the long-term average and ranking in the warmest third of the 101-year record. While parts of the southeast Panhandle were slightly cooler than average, the North Slope was notably warm at more than 3 degrees above average.
The average temperature for the CONUS during the first half of 2025 (January–June) was 49.6°F, 2.1°F above the 20th-century average, ranking in the warmest third of the 131-year record. All states recorded temperatures above their long-term averages for the six-month period, with much-above-average warmth observed across parts of the West, Southwest and portions of the East Coast. Alaska’s year-to-date average temperature was 26.8°F, 5.5°F above its long-term average, tying as the fourth-warmest January–June in the 101-year record.
Precipitation
June 2025 U.S. Total Precipitation Percentiles
The average precipitation for the contiguous U.S. in June was 3.22 inches, 0.30 inch above the long-term average, ranking in the wettest third of the 131-year record. Much of the Southwest, the southern and central Plains, the middle and upper Mississippi Valley, parts of the Ohio Valley and Great Lakes region and areas of the Deep South recorded above-average rainfall. In contrast, drier-than-average conditions prevailed from the central West Coast through the Northwest and into the Rockies. The Northwest region experienced its third-driest June on record—and driest since 2003—with Washington and Oregon each receiving less than half an inch of rain for the month. Parts of north-central California and south-central Washington recorded no measurable rainfall for the entire month.
For the January–June period, the CONUS averaged 15.70 inches of precipitation, 0.40 inch above the long-term average, ranking in the middle third of the 131-year record. Most of the western half of the country, along with a narrow band from the central Plains through the mid-Mississippi Valley and parts of the Southeast, were drier than average. Above-average precipitation was recorded from the southern Plains through the lower Mississippi and Ohio Valleys into the Northeast, as well as in parts of the northern Plains and upper Mississippi Valley.
Alaska received 2.32 inches of precipitation in June, which was near the long-term average. Conditions were drier than average across the eastern interior and North Slope but wetter than normal in the western and southwestern parts of the state. For the first half of the year, Alaska recorded 16.58 inches of precipitation, 2.96 inches above average, marking its fifth-wettest start to the year on record.
Drought
According to the July 1 U.S. Drought Monitor report, about 32.4% of the contiguous U.S. was in drought, an increase of approximately 2.8% since the beginning of the month. Drought developed or intensified across much of the Northwest through the Rocky Mountains and in small areas of the Alaskan interior. Conversely, drought contracted or was reduced in intensity across parts of the Southwest and southern Texas, the central and northern Plains, the upper Mississippi Valley and parts of Florida.
Monthly Outlook
July temperatures are expected to be above normal across the entire contiguous U.S., with the highest likelihood of warmer-than-average conditions in the Mountain West, southern Texas and throughout much of the Great Lakes and the Northeast. For rainfall, parts of the Northwest and the southern and central Plains are expected to be drier than normal, while the interior East is favored to have a wetter-than-average July. Drought is likely to persist across much of the western U.S. in July, with some further development in the Northwest, while improvement is expected across southeastern Arizona, southern New Mexico and far West Texas, where above-average rainfall is favored.
