The beach is adjacent to the Canal da Barra, which acts as the tidal drainage point for the Maricá-Guarapina lagoon complex.
The community of Zacarias, located at the beach entrance, is an officially recognized artisanal fishing village.
The local substrate is primarily fine quartz sand, typical of the sedimentary deposits found along the Restinga de Maricá.
The strong rip currents at this location are generated by the interaction of the tide and the outflow of the lagoon channel.
Praia da Barra in Maricá is characterized by its expansive stretch of sand and notably strong oceanic currents that demand caution from swimmers. It serves as the primary meeting point between the Atlantic Ocean and the Maricá lagoon system through the Barra de Maricá channel. The area is backed by the residential neighborhood of Zacarias, known for its traditional fishing community. The beach is exposed to open sea swells, creating consistent wave activity favored by local surfers. The geography of the coastline features a long, linear barrier beach formation separating the inland lagoons from the sea. Erosion and sand deposition from the channel outlet continuously alter the immediate shoreline topography.

Prioritize swimming only in areas patrolled by lifeguards, as rip currents are frequent and powerful.
Visit during low tide if you intend to walk along the water's edge, as high tide significantly reduces the dry sand area.
Bring your own shade equipment, as the beach has very limited natural vegetation or structured shelter.
Attempting to swim near the mouth of the channel, where currents are intensified by tidal exchanges.
Standard beach attire is expected; observe all red flag warnings regarding water safety.
