The latest monthly summary of climate for the United States was released this morning by NOAA. It shows that for the US, the average June temperature was 3.0 degrees above the 20th century average. That makes it the third warmest since records began in 1895, after 1933 and 2016. For the January through June period, it was the 14th warmest on record, although there were a lot of swings in space and time across the US during those six months.
