Weather in Antarctica

Milder Than You May Expect

Tabular iceberg in mild weather in Antarctica

With very few exceptions, all of our Antarctica cruises visit the Antarctic Peninsula. This is the long arm of land that stretches northward toward the southernmost tip of South America. It is often referred to as the “Banana Belt” of Antarctica because temperatures on the peninsula are considerably milder than anywhere else on the continent.

Furthermore, our trips operate during the austral summer (roughly November through March) when temperatures are warmest. By most people’s standards, it will be cold, but you will be pleasantly surprised at how easy it is to keep comfortably warm during your trip...with the right clothing! (See Dressing For Your Antarctica Cruise)

At the Antarctic Peninsula, we may experience a wide variety of weather, from snow to intense sunshine. Temperatures can change rapidly and without warning and katabatic winds—cold air that rushes downslope over a land mass—can kick up at any time. While always a possibility, snowstorms at the Antarctic Peninsula occurs less often than one might think, especially during the summer months when we visit.

During the cruise season, rarely does it get much colder than during the winter months in much of the northern US. During the warmest months, it is not all that unusual to have an  occasional day in the high 40s or even low 50s Fahrenheit.

The table below will give you a general sense of daytime temperatures you can expect during your trip:

Average temperatures during the Antarctica cruise seasonA good way to get a general idea of current temperatures at the Antarctic Peninsula is to read the weather report for Base Esperanza, an Argentine research station located on the peninsula.
