Air Temperature

The global land and ocean temperature departure from average for January 2019 was third highest on record for the month of January.

According to the U.S. Climate Report, 2018 became the 22nd consecutive warmer-than-average year and was the 14th warmest on record.

The globally averaged temperature over land and ocean surfaces for 2018 was 1.42°F (0.79°C) above the 20th century average.

The global land and ocean temperature departure from average for November 2018 tied with 2004 and 2016 as the fifth highest for the month of November in the NOAA global temperature dataset record, which dates back to 1880. The September–November temperature was the second warmest period on record and the year-to-date global temperature was the fourth warmest period on record. This monthly summary, developed by our scientists, is part of the suite of climate services NOAA provides to government, business, academia and the public to support informed decision-making. November 2018 Temperature The November temperature across global land and ocean surfaces was 1.35°F above the 20th century average of 55.2°F and tied with 2004 and 2016 as the fifth highest for November in the 1880–2018 record. November 2015 is the warmest November with a global temperature at 1.73°F above average. November 2018 also marks the 42nd consecutive November and the 407th consecutive month with temperatures, at least nominally, above the 20th century average. Record warmth was limited to mostly ocean areas, specifically across parts of the Barents Sea, central and southern Atlantic Ocean, and parts of western Pacific Ocean. No land or ocean areas had record cold November temperatures. The November

During November, the average contiguous U.S. temperature was 40.1°F, 1.6°F below the 20th century average.

The global land and ocean temperature departure from average for October 2018 was second highest on record for the month of October.

During October 2018, the average contiguous U.S. temperature was 53.8°F, 0.3°F below the 20th century average.

NCEI releases a new version of the widely used global land temperature dataset known as the Global Historical Climatology Network–Monthly.

The global land and ocean temperature departure from average for September 2018 was fourth highest on record for the month of September.

During September 2018, the average contiguous U.S. temperature was 67.8°F, 2.9°F above the 20th century average.
