The globe continued to simmer in exceptional warmth, as September 2019 tied with 2015 as the hottest September in NOAA’s 140-year temperature record. The month also capped off another warm year so far, with the globe experiencing its second-warmest January through September (YTD) ever recorded.
Below are highlights from NOAA’s latest monthly global climate report:
Climate by the numbers
The average global land and ocean surface temperature for September 2019 was 1.71 degrees F (0.95 degrees C) above the 20th-century average and tied 2015 as the highest September temperature departure from average since global records began in 1880.
Septembers for 2015, 2016 and 2019 were the only Septembers with a global land and ocean surface temperature departure from average greater or equal than 1.62 degrees F (0.90 degrees C).
September 2019 was also the 43rd consecutive September and the 417th consecutive month with temperatures — at least nominally — above the 20th-century average.
Year to date | January through September
The first nine months of the year each had a global land and ocean temperature departure from average that ranked among the five warmest for their respective months. This gave way to the second-warmest January-through-September period in the 140-year record with a temperature of 1.69 degrees F (0.94 degrees C) above the 20th-century average. This was 0.22 degrees F (0.12 degrees C) cooler than the record-warm year to date set in 2016 and only 0.02 degrees F (0.01 degrees C) warmer than the now third- warmest year to date set in 2017.
