Climate Highlights — June: “The average temperature for the contiguous U.S. during June was 71.2°F, which is 2.0°F above the 20th century average. The June temperatures contributed to a record-warm first half of the year and the warmest 12-month period the nation has experienced since recordkeeping began in 1895. Scorching temperatures during the second half of the month led many cities to set all-time temperature records.”
