Sea Ice Outlook: 2019 Interim Post-Season Report
Outlook Report
Executive Summary
The Arctic has reached the end of the 2019 summer melt season. The September monthly averaged sea ice extent was 4.32 million square kilometers, based on the National Snow and Ice Data Center (NSIDC) Sea Ice Index (SII). This is the third lowest in the satellite record that began in 1979. The median extent of the Outlook contributions for June (31 contributions), July (39 contributions), and August (42 contributions) were 4.40, 4.28, and 4.22 million square kilometers, respectively. Overall, the Outlooks
Sea Ice Outlook: 2019 August Report
Outlook Report
Executive Summary
Thank you to the groups that contributed to this 2019 August Sea Ice Outlook (SIO) report. This activity would not be possible without the dedication of so many people who contributed to the 2019 and previous SIOs that include Pan-Arctic, Antarctic, and regional forecasts. The 2019 August Sea Ice Outlook received a record number of 42 submissions (31 in June, 39 in July). These outlook contributions are based on a variety of methods, including dynamical (physics-based) models, statistical approaches, heuristic (qualitative), and a forecast
Sea Ice Outlook: 2019 July Report
Outlook Report
Executive Summary
Thank you to the groups that contributed to this 2019 July Sea Ice Outlook (SIO) report. We received 39 contributions that include pan-Arctic predictions, which is tied with the record number of contributions received for the Sea Ice Outlook. Combined with the contributions to the 2019 June SIO report, we have received a total of 70 contributions this season. We also received two new Antarctic contributions, for a total of 8 for June and July, and 10 additional Alaska contributions in July for a total of 19 so far.
The projected median
Sea Ice Outlook: 2019 June Report
Outlook Report
Executive Summary
Thank you to the groups that contributed to this 2019 June Sea Ice Outlook (SIO) report. We received 31 contributions that include pan-Arctic predictions; of those contributions, six also included pan-Antarctic predictions, and nine included predictions for Alaskan waters. This year, for the first time, there are also seven predictions for the Hudson Bay region.
For the pan-Arctic, the median June Outlook value for September 2019 sea-ice extent is 4.40 million square kilometers with quartiles of 4.2 and 4.8 million square kilometers (see

Sea Ice Outlook: 2018 Interim Post-Season Report
Outlook Report
Executive Summary
The 2018 Arctic summer melt season has come to a close. The September monthly averaged sea ice extent was 4.71 million square kilometers, based on the National Snow and Ice Data Center (NSIDC) Sea Ice Index. This ranks as effectively tied with 2008 for the 6th lowest in the satellite record that began in 1979. The median extent of the 39 Outlook contributions for June, July, and August were 4.60, 4.70, and 4.57 million square kilometers, respectively. Overall, the Outlooks performed well, with the observed extent falling within the interquartile

Sea Ice Outlook: 2018 August Report
Outlook Report
Executive Summary
The 2018 August Sea Ice Outlook (SIO) for September ice conditions received 39 (34 in June, 39 in July) contributions, variously based on dynamical (physics-based) models, statistical approaches, heuristic (qualitative), and mixed methods. Along with projections of total Arctic sea ice extent for September, the SIO received 10 (10 in June, 9 in July) projections of Antarctic total ice extent and 11 (11 in both June and July) projections of ice extent in the Alaskan sector (combining the Bering, Chukchi, and Beaufort Seas).
