Exceptional heat waves from coast to coast helped push June 2021 to the No. 1 spot on the list of hottest Junes on record for the U.S.

Climate by the numbers
The average June temperature across the contiguous U.S. was 72.6 degrees F (4.2 degrees above average), making it the hottest June in 127 years of record keeping and surpassing the record set in June 2016 by 0.9 of a degree.
Eight states — Arizona, California, Idaho, Massachusetts, Nevada, New Hampshire, Rhode Island and Utah — also saw their hottest June on record. Six other states — Connecticut, Maine, Montana, Oregon, Washington and Wyoming — marked their 2nd hottest June.
The average June precipitation across the U.S. was 2.93 inches, matching exactly the historical average for the month, though some states had extremes in rainfall — either too much or too little. For example, South Dakota saw its driest June on record while Mississippi had its second wettest.
