Swimming conditions at Praia da Carlota can be challenging due to Atlantic currents and waves typical of Boa Vista's exposed coastline. The beach is relatively undeveloped with no lifeguards on duty, so swimmers should exercise caution and assess conditions carefully. Currents can be strong, particularly during winter months. The remote location means help is not immediately available. Strong swimmers may enjoy the water during calmer periods, but families with children should be especially vigilant. Always check local conditions and never swim alone at this isolated beach.

The best time to visit Praia da Carlota is during the dry season from November to June, when you'll encounter less wind and clearer skies. For those seeking solitude, weekdays are ideal as this hidden beach sees fewer visitors than Boa Vista's main beaches. Early morning or late afternoon offers the most pleasant temperatures and beautiful light for photography. The beach is particularly peaceful during shoulder seasons (November-December and May-June) when tourist numbers are lower across the island, though the stunning white sand and dunes are enjoyable year-round.
