Between the months of April and September, the South Pole averaged a temperature of -61.1C (-78F).
Simply put, this was the region’s coldest 6-month spell ever recorded, and it comfortably usurped the previous coldest ‘coreless winter‘ on record — the -60.6C (-77F) set back in 1976 (solar minimum of weak cycle 20).
is confirmed by Antarctica climatology journalist Stefano Di Battista who has closely watched and published research on Antarctic temperatures for many years:
1/1 Extraordinary coreless winter (April – September) at South Pole Station. The average as been -61.1 °C the coldest ever recoded. This value set -2.2 °C on the reference 1981-2010 and -2.5 °C on 1991-2020. Previous record -60.6 °C in 1976 pic.twitter.com/m8uWF5mt0c

Battista also points out that for June, July, August and September the average temperature for each of these month finished-up below -60C (-76F) — a phenomenon that has occurred on just 3 previous occasions: in 1971, 1975 and 1978.
