  • The November globally averaged land surface temperature was 1.71°F above the 20th century average of 42.6°F. This value was the 12th highest November land global temperature in the 1880–2016 record.
  • The November globally averaged sea surface temperature was 1.17°F above the 20th century monthly average of 60.4°F. This value was the second highest global ocean temperature for November in the 1880–2016 record, 0.34°F lower than the record warmth of November 2015.
  • Snow cover across the Northern Hemisphere was 1.15 million square miles (8.7 percent) above the 1981–2010 average. This was the fourth largest snow cover extent of the record, which dates to 1966. North American snow cover extent was slightly below average while the Eurasian snow cover extent was the second largest on record.
  • The average Arctic sea ice extent for November 2016 was 750,000 square miles (17.7 percent) below the 1981–2010 average, according to analysis by the National Snow and Ice Data Center using data from NOAA and NASA. This was the smallest November extent since records began in 1979. Sea ice growth was abnormally slow during the first and third weeks of November. Daily sea ice extent values were record low throughout the month.
  • Antarctic sea ice extent during November 2016 was 700,000 square miles (11.1 percent) below the 1981–2010 average. This was the smallest Antarctic sea ice extent on record for November.
