July 2012: Hottest Month In U.S. History. Accurate weather records go back to the late 1800s. Since then there has never been a month as hot as July, 2012. Details from NOAA: “According to NOAA scientists, the average temperature for the contiguous U.S. during July was 77.6 F, 3.3 F above the 20th century average, marking the hottest July and hottest month on record for the nation. The previous warmest July for the nation was July 1936, when the average U.S. temperature was 77.4 F. The warmest July temperatures contributed to a record-warm first 7 months of the year, and the warmest 12-month period the nation has experienced since record-keeping began in 1895. Just looking at the map I was struck with the thought that this gives new meaning to “red states”.
