Despite its low latitude, Punta Arenas has a subpolar oceanic climate bordering on a tundra climate. The seasonal temperature in Punta Arenas is greatly moderated by its proximity to the ocean. This is not to say that it is known for stable, constant temperatures but only small variability within each season. The city is also known for its strong winds that tend to be strongest during the summer. Since 1986, Punta Arenas has been the first significantly populated city in the world to be affected directly by the thinning in the ozone layer. Even if you cannot feel it, the sun is incredibly strong, which can cause a serious sunburn in a very a short period of time. It is highly recommended travelers use sunscreen on all exposed areas of skin.
