Halfway through 2018, the U.S. is having its 14th warmest year on record, with the Southwest leading the way.


2018 U.S. Temps: State Rankings Through June

With the release of the monthly global temperature analysis from NOAA today, it is a good opportunity to compare temperatures so far this year to their historical levels. And as greenhouse gases continue to accumulate in the atmosphere, the heat goes on both globally and here in the U.S.

Despite a cold April, 2018 is the 14th warmest year on record so far in the U.S. Halfway through the year, Arizona and New Mexico are record hot, and the remaining southwestern states are each having one of their 10 hottest years. In fact, the four hottest years in the U.S. have all come in the decade of the 2010s.

July has been a scorcher from West to East. On July 6, the temperature on the UCLA campus reached 111°F, breaking the all-time record high of 109°F set in 1939. That same day in downtown Los Angeles, a new daily record high of 108°F smashed the previous one by 14°F (94°F in 1992). Famously cold Mount Washington, New Hampshire (elevation 6289’) did not drop below 60°F on July 3, tying its all-time warmest low temperature record. Other weather extremes have led to six separate billion-dollar disasters so far in 2018, on the same pace as the number of these disasters in 2008 and 2012.

Methodology: U.S. and global temperature rankings referred to in the text above are calculated by NOAA/NCEI. Monthly global temperature analyses are also independently calculated by NASA. Climate Central combines the NOAA and NASA information to re-baseline global temperatures using an earlier pre-industrial baseline of 1881-1910 in response to the Paris Climate Change Agreement.
