Antarctica is the coldest continent on earth, and has a climate of extremes. The continent is snow- and ice-covered, with freezing temperatures all year round. So-called "Catabian winds" can cause violent snowstorms that can last for days, and sometimes even weeks, making it very dangerous to stay outside. Antarctica knows periods of continual daylight an darkness, called "polar summer" (end May - Sept) and "polar winter" (end Nov - March).
The polar summer with daytime temperatures between -20°C and -5°C is the only time to travel to Antarctica, because the conditions are too bad during the winter months, with extreme cold temperatures, violent storms, continous darkness and ice-bound seas.
Note: Be prepared to extreme weather conditions at any time. The Weather can change very quickly in Antarctica, sunshine can change to a serious snowstorm from one moment to another.
Special (Expedition) clothing for Extreme low Temperatures is needed to visit Antarctica. These clothes are only available in Special Stores, please contact your Travel organisation for more information when you're planning to visit Antarctica.
Antarcticas Climate can be classified as E climate, an extreme cold climate with the warmest month under 10°C.
