The globally averaged temperature departure from average over land and ocean surfaces for 2019 was the second highest since record keeping began in 1880, according to NOAA scientists. December’s combined global land and ocean surface temperature departure from average for 2019 was also second highest in the 140-year record.
In a separate analysis of global temperature data, released today, WMO, NASA and Copernicus scientists determined 2019 to also be the second warmest year on record. Analyses from the United Kingdom Met Office ranked 2019 among the top three warmest years on record.
From the U.S. Report
For 2019, the average contiguous U.S. temperature was 52.7°F, 0.7°F above the 20th century average. This ranked in the warmest third of the 125-year period of record and was the coolest year since 2014. Below-average temperatures, particularly daytime temperatures, were observed across the northern Plains, while above-average to record-warm overnight temperatures dominated across the Southeast and Mid-Atlantic.
The annual precipitation total for the contiguous U.S. was 34.78 inches, 4.84 inches above average, the second wettest year on record and 0.18 inch less than the total for the wettest year set in 1973*. Record precipitation fell across the northern Plains, Great Lakes and portions of the central Plains. Ten of the last twelve 12-month periods were record wet with the top seven all-time wettest 12-month periods occurring during 2019.
