McMurdo Sound provides an important component in Antarctica's global effects upon climate. A key factor is the polar winds that can drive the sound's pack ice into the Ross Sea summer or winter. Frigid katabatic winds rake subsequently exposed water, causing sea ice to form.
The coast is warmer; on the coast Antarctic average temperatures are around −10 °C (14.0 °F) (in the warmest parts of Antarctica) and in the elevated inland they average about −55 °C (−67.0 °F) in Vostok. [13] [14] Monthly means at McMurdo Station range from −26 °C (−14.8 °F) in August to −3 °C (26.6 °F) in January. [15]
McMurdo has the world's most southerly harbor, this is important for bringing supplies to McMurdo and in support of projects in the Antarctic, but weather conditions necessitate an icebreaker. An example of a resupply ship is the MV American Tern , which was chartered from 2001-2010.
Record high temperatures reportedly measured in Antarctica will take months to verify, the U.N. weather agency said Sunday. A spokesman for the World Meteorological Organization said the ...

Pending the final data, in Vostok the value of -20.3 °C set the new monthly record but also exceeds the maximum of February (-22.2 °C on 2009, day 6) and November (-22.0 °C on 1974, day 23) pic ...
While 2024 has been extremely warm, what kicked this week into new territory was a warmer-than-usual Antarctic winter, with temperatures 6 to 10 degrees Celsius (10.8 to 18 degrees Fahrenheit ...
The AMRC is one of the primary archives of meteorological data from Antarctica and its surrounding geographic areas. [1] The Antarctic Meteorological Forecast Center (AMFC) at UW-Madison was devised during the same time as the founding of the AMRC as a provider of weather forecasts for research vessels operating in the vicinity of Antarctica.
