October Temps

• The October average temperature across global land and ocean surfaces was 1.76°F (0.98°C) above the 20th century average. This was the highest for October on record, surpassing the previous record set last year by 0.36°F (0.20°C), and marked the sixth consecutive month a monthly global temperature record has been broken. This record departure from average was also the highest on record for any month, surpassing the previous record set last month by 0.13°F (0.07°C).
• The October globally-averaged land surface temperature was 2.39°F (1.33°C) above the 20th century average. This was the highest for October in the 1880–2015 record, surpassing the previous record set in October 2011 by 0.31°F (0.17°C).
• The October globally-averaged sea surface temperature was 1.53°F (0.85°C) above the 20th century average. This was the highest temperature for October in the 1880–2015 record surpassing the previous record set last year by 0.27°F (0.15°C). This was also the highest departure from average for any of the 1630 months of recordkeeping, surpassing the previous record set last month by 0.07°F (0.04°C).
• The average Arctic sea ice extent for October 2015 was 460,000 square miles (13.4 percent) below the 1981–2010 average. This was the sixth smallest October extent since records began in 1979, according to analysis by the National Snow and Ice Data Center using data from NOAA and NASA.
• Antarctic sea ice extent during October 2015 was 90,000 square miles (1.3 percent) below the 1981–2010 average. This was the 14thlargest Antarctic sea ice extent on record. On October 6th, the Antarctic sea ice extent reached its annual maximum extent at 7.24 million square miles, slightly above average and in contrast to the past three years when record large maximum sea ice extents were observed.
