<!--!introduction!--> Antarctic Sea ice prediction has garnered increasing attention in recent years. Spurred by recent studies that uncovered mechanisms of Antarctic sea ice predictability and by the intriguing large variations of the observed sea ice extent in recent years, the Sea Ice Prediction Network South (SIPN South) project was initiated in 2017. The SIPN South project annually coordinates spring-to-summer predictions of Antarctic sea ice conditions, to allow robust evaluation and intercomparison, and to guide future development in polar prediction systems. In this contribution, we present and discuss the initial SIPN South results collected over the six previous summer seasons. We use data from 21 unique contributors spanning five continents that have together delivered more than 3000 individual forecasts of sea ice area and concentration. The SIPN South median forecast of the circumpolar sea ice area captures the sign of the recent negative anomalies, and the verifying observations are ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
