The June report for the 2018 Sea Ice Outlook (SIO) is now available online. The goal of the SIO is to improve Arctic sea ice prediction on seasonal time-scales. For June, we received 34 contributions that include pan-Arctic predictions, of those contributions 10 also included pan-Antarctic predictions and 11 included predictions for Alaskan waters. We received one additional contribution with a regional focus on the Nares Strait. For the Arctic, the median June Outlook value for a September 2018 sea ice extent projection is 4.6 million square kilometers. The June report includes analysis of the contributions, predicted spatial fields with discussion on sea ice probability (SIP) and the first ice-free day (IFD) from a number of dynamical models; a section on current conditions with discussion on this winter's record low sea ice conditions and atmospheric conditions; a section discussion regional ice conditions; and a section discussing Antarctic sea ice extent forecasts.
