FRISCO — With an average temperature of 2.9 degrees Fahrenheit above the 20th century average, last month was the second-warmest June on record for the contiguous United States, ranking behind June 1933, according to the latest monthly update from NOAA’s National Climatic Data Center.

The West was sweltering, as five states (California, Oregon, Washington, Idaho, Utah) set all-time June temperature records. Wyoming, Montana and Nevada reported June temps that were in the all-time top five, while Colorado and New Mexico’s June readings were in the top ten warmest on record.

For the year to date, the U.S. average temperature was the 10th-warmest on record, 2.9 degrees Fahrenheit above the 20th century average.

In the past 30 days, 25 weather sites across the country have broken all time daily maximum high temperature records; 56 sites reported breaking all-time high minimum temperatures. There have been no daily low temperature records set in the past 30 days.

Several western cities set new all-time June temperature records during an intense heatwave the second half of the month, including Boise, Idaho where the temperature soared to 110 degrees Fahrenheit.

Alaska reported its sixth-warmest June on record, 3.1 degrees Fahrenheit above average, with Homer reporting a record-warm June. A hot and dry early spring and summer across Alaska set the state for what already is the state’s worst wildfire season on record.

June was the ninth-wettest on record and the third straight month with above-average precipitation for the Lower 48 states. The wettest regions were the Southwest, the Southern Plains, the Ohio Valley, and the Northeast, while the Northwest was dry.

For the year to date, five states have been record-warm: Florida, California, Nevada, Oregon and Washington, while another eight states reported much warmer than average temperatures. California broke its year-to-date record, set just last year, by 0.5 degrees Fahrenheit.

The coolest parts of the U.S. for the year to date were in the Midwest and Northeast, where Maine, New York, and Vermont were each much cooler than average. No state was record cold for the six-month period.
