Even though Antarctica is known for being extremely cold in the winter, in the summer it can actually be quite nice, with temperatures hovering around freezing. When we were there the coldest temperature we saw was -5 degrees celsius. But it’s possible for the mercury to drop to -20 in the summer. The wind brings this down even more. Don’t worry, you won’t freeze, even if you are camping in Antarctica. If conditions are too dangerous the expedition leader will come up with alternatives to keep everyone safe.
