Swimming is not recommended at Sandefjord Bay Beach due to Antarctic waters averaging -1°C to 2°C year-round, which can cause cold shock and hypothermia within minutes. The pebble beach and surrounding waters present extreme conditions unsuitable for recreational swimming. Visitors should maintain safe distances from the shoreline and never enter the water without specialized cold-water survival equipment and professional supervision during organized expeditions.

The Antarctic summer months from November through March offer the only viable visiting window, with December and January providing the best weather conditions. During this period, temperatures reach slightly above freezing, sea ice breaks up allowing ship access, and wildlife activity peaks. February and March see fewer expedition vessels, offering more solitude. Outside these months, the area is locked in ice and 24-hour darkness makes access virtually impossible for tourism.
