Swimming at Potter Cove Beach is unsafe and generally not permitted. Antarctic waters remain near or below freezing, causing rapid hypothermia. The cove is an active research area adjacent to Argentina's Carlini Station, with strict environmental protocols limiting human impact. Scientific equipment and ongoing studies make recreational activities inappropriate. Visitors on expedition cruises may land briefly under guide supervision for wildlife observation and photography, but water contact beyond accidental splashes during Zodiac landings should be avoided entirely.

Visit Potter Cove Beach during the Antarctic summer, November through March, when temperatures are relatively milder and daylight extends nearly 24 hours. December through February offers the best combination of wildlife activity, accessible sea conditions, and stable weather patterns, though Antarctic weather remains unpredictable. This period coincides with penguin breeding seasons and seal pupping. Research activity at nearby Carlini Station is also most active then, though station visits require special arrangements separate from standard expedition cruise itineraries.
