Like the coastal areas of Antarctic Peninsula and the subantarctic islands south of the 60º parallel, the area has a tundra climate, that could be considerably borderline "maritime-influenced polar climate", thanks to temperatures that rarely drop below in winter (which is commonplace in most of Antarctica), and temperatures that could soar a few digits above freezing for most parts of the year. The base's area and its vicinity (the entire island, actually) experiences a rather heavy precipitation, with an average precipitation rate of yearly, which makes it unusual on the Antarctic continent, as the continent is significantly drier than the islands are to the north. ==See also==
