Antarctica Sets New March Cold Record At -76.4C (-105.5F); Canada Hits Spring Extremes; Juneau Sets All-Time Snowfall Record; Alps Snow Blast To Deliver 100cm (39 in); + Third SSW
Antarctica is locking into winter fast this year—and has never been colder in the month of March (observations back to ~1957).
Antarctica Sets New March Cold Record At -76.4C (-105.5F)
Antarctica has just reset the bar for March cold.
On March 25, temperatures at Vostok Station fell to -76.4C (-105.5F), establishing a new March record for the continent.
The previous benchmark stood at -75.7C (-104.3F), recorded at Dome Fuji in 2013 (though this is considered unreliable), with other notable lows including -75.5C (-103.9F) at Plateau Station (1967) and Concordia (2025).
At Vostok itself, the prior March low was -75.3C (-103.5F), observed in 1982, 2020, and again yesterday (March 24, 2026).
Clear skies, extremely low humidity, and a stable air mass allowed for intense radiational cooling over the high Antarctic Plateau. With the sun rapidly disappearing below the horizon at this time of year, heat loss accelerates quickly.
March marks the beginning of the descent into Antarctica’s long winter phase. However, values this low are more characteristic of the deep winter core between July and August.

Canada Hits Spring Extremes
Northern Canada remains locked in midwinter conditions, with record-level cold persisting into late March.
