“Feels-Like” Temperatures

The way we experience weather isn’t all about temperature. Higher temperatures affect us much more at higher humidity, and colder temperatures feel piercing with high winds. Our perceived temperatures factor in humidity and wind chill to better represent how hot or cold the day feels to a person.

Precipitation (Rain or Snow)

If dry weather is what you’re after, the months with the lowest chance of significant precipitation in Antarctica are December, July, and then September. Note that we define “significant precipitation” as .1 inches or more in this section. The lowest chance of rain or snow occurs around early to mid July. For example, on the week of July 9th there are no days of precipitation on average. By contrast, it’s most likely to rain or snow in early May with an average of 0 days of significant precipitation the week of April 30th.

When can you find snow in Antarctica? Weather stations report far greater snow than most tourist destinations snow through most of the year likely to be deepest around October, especially close to late October. The best time to ski (if at all) in Antarctica is often around around December 17th when fresh powder is deepest. Please note that a value of 0 for snow in the graph below may either mean there was no snow, or that snow is unreported.

Antarctica has some humid months, and above average humidity throughout the year. The least humid month is July (60.8% relative humidity), and the most humid month is January (67.7%).

Wind in Antarctica is usually stronger than many places. The windiest month is June, followed by April and May. June’s average wind speed of around 14.3 knots (16.5 MPH or 26.5 KPH) is considered “a moderate breeze.” Maximum sustained winds (the highest speed for the day lasting more than a few moments) are at their highest in early June where average top sustained speeds reach 23.8 knots, which is considered a strong breeze.

Overall Antarctica Travel Experience by Season

Fall (March through May)

Humidity and temperatures combine to make this season feel very cold. Highs range from 7.4°F (-13.7°C) and -10.1°F (-23.4°C) with colder temperatures in the later months. Rain is rare with roughly 1 days of significant precipitation per month. Fall is fairly slow for tourism, which makes it a good time for those looking for deals.

Winter (June through August)

The middle-year months have freezing weather with high temperatures that are still very cold. These months see the least precipitation with about 1 days of precipitation per month. June – August is the second busiest season for tourism in Antarctica, so lodging and other accommodations may cost slightly more.

Spring (September through November)

Spring daily highs range from 16.5°F (-8.6°C) and -12.3°F (-24.6°C), which will feel very chilly given the humidity and wind. It rains or snows a normal amount: approximately 1 days per month. Tourism is the slowest during these months due to the weather, so hotels may be affordably priced.

Summer (December through February)

Weather is far too cold this time of year in Antarctica to be enjoyable for warm weather travelers. The average high during this season is between 23.6°F (-4.7°C) and 7.4°F (-13.7°C). On average, it rains or snows a smalll amount: consistently 1 times per month. These times of year are the busiest with tourists.
