39th Daily Record of Year for Antarctic Sea Ice Extent
September 34 (Day 247) saw the 39th Daily Record of the Year for Antarctic Sea Ice Extent.
Antarctic Sea Ice Extent is 19.16 million sq km.
If you add up the number of daily records, 2013 is a distant 3rd behind 2008 and 2010. However, if you also add in 2nd place finishes, 2013 slightly edges out 2010. And 118 days remain in the year.

Global Sea Ice Extent Anomaly Only 170,000 sq km = 0.7%
If you add up the Antarctic Sea Ice Extent Anomaly from the 30 year mean and the Arctic Anomaly and divide by the 30 year mean it comes to 170,000 sq km. Out of a normal mean of 24,700,000 sq km on Day 239.
That is a whole 0.7% below normal. The red part is above normal. The blue is below normal.
The highest anomaly for 2013 was March 14th when the anomaly was 908,000 out of a mean of 19.2 million for an anomaly percent of 4.72%.
31st Daily Record of Year for Antarctic Sea Ice Extent (8th in a row)
August 26 (Day 238) saw the 31st Daily Record of the Year for Antarctic Sea Ice Extent. This was the 8th record in a row.
Antarctic Sea Ice Extent is 19.03962 million sq km. That is 1,000,000 sq km higher than the 30 year mean.
With still 2 – 4 weeks left in the Antarctic Freeze Season, 2013 Sea Ice Extent has already surpassed 25 years yearly maximums.
Only the following years have had more ice: 1980, 1998, 2000, 2004, 2005, 2006, 2007, 2009, 2012.
