For tourists, Antarctica is accessible only during the austral summer season from November to March, during which sea ice melts enough to allow access, coastal temperatures can rise up to highs of 14°C (57°F) and there are twenty four hours of daylight. During the winter the sea is impassable. Temperatures can fall to -40°C/F and there are twenty four hours of darkness.
The above temperatures apply to the islands and coastal regions that tourists ordinarily visit. Temperatures in the interior, such as the South Pole, are far harsher, with summer highs of around -15°C (5°F) and winter lows plummeting to -80°C (-112°F).
