Line graph time series of 2023's daily Antarctic sea ice extent anomaly compared to 2016, which was the record for the largest magnitude sea ice anomaly. 2023 is a record for low for the current date. The range in sea ice anomalies between 1979 and 2022 is also shown. Anomalies are computed to a 1981-2010 baseline using passive microwave satellite data.

Well, the absolute magnitude of the #Antarctic sea ice anomaly has now tied the largest on record...

Note that while sea ice is growing (austral winter), it's happening much slower than typical.
I am using the National Snow and Ice Data Center (NSIDC) 5-day running mean (https://nsidc.org/data/seaice_index/faq). Data from https://nsidc.org/data/seaice_index.
