The temperature average across global land and ocean surfaces indicated that August 2019 was the second-warmest August since the National Oceanic and Atmospheric Administration began keeping records in 1880. The average global temperature was 1.66 degrees Fahrenheit more than the 20th-century average of 60.1 degrees Fahrenheit. According to National Oceanic and Atmospheric data, 2019 tied with 2015 and 2017 as having the world’s warmest August.

The five-warmest Augusts have all occurred since 2014. August 2016 is the warmest on record with a global land and ocean-surface temperature 1.76 degrees Fahrenheit more than the 20th-century average.

Record-warm August temperatures prevailed across parts of the northern and western Pacific Ocean, the Bering Sea, northern and southern parts of North America, the Atlantic Ocean, the Indian Ocean, and parts of Africa and central Asia.

The August globally averaged land-surface temperature was 2.05 degrees Fahrenheit more than the 20th-century average of 56.9 degrees Fahrenheit. The August globally averaged sea-surface temperature was 1.51 degrees more than the 20th-century monthly average of 61.4 degrees Fahrenheit. That meant August 2019 had the warmest sea-surface temperature on record.

June-August temperatures reported

The June through August 2019 average temperature across global land and ocean surfaces was 1.67 degrees Fahrenheit warmer than the 20th-century average of 60.1 degrees Fahrenheit. The three-month period had the second-greatest temperatures on record for the June-August period.

The global land and ocean-surface temperature for the three-month season increased at an average rate of 0.13 degrees Fahrenheit per decade since 1880. The average rate of increase per decade since 1981 is more than twice as great at 0.32 degrees Fahrenheit.
