The water temperature in this region remains consistently between 24°C and 28°C throughout the year.
The beach is part of the Costa dos Corais Environmental Protection Area, Brazil's largest federal coastal marine conservation unit.
During peak low tides, the receding ocean reveals extensive sandbanks that create natural lagoons up to one kilometer from the main shoreline.
The high concentration of coral and algae in the surrounding reef ecosystem contributes to the distinct turquoise hue of the water.
The area's extreme shallowness makes it a frequent location for seeing local marine life, including small fish and crustaceans, without the need for deep-water diving equipment.
Praia de Antunes is a coastal stretch in Maragogi known for its expansive, shallow turquoise waters and sandbars that appear during low tide. The beach features a calm, reef-protected shoreline suitable for wading long distances away from the sand. It is characterized by high water transparency and a lack of heavy surf due to the Coral Coast barrier reef system. The coastline is bordered by coconut palm groves and informal, rustic beach kiosks. Unlike the more crowded central Maragogi beaches, Antunes maintains a more open, expansive landscape. The seabed consists of soft, white fine-grain sand without significant rock formations. It serves as a primary transit point for boat tours visiting the Maragogi natural swimming pools.

Monitor the local tide tables; the most impressive features are only accessible during 'maré baixa' (low tide) of 0.3 meters or less.
Bring polarized sunglasses to better observe the reef structures and marine life beneath the water's surface.
Water shoes are recommended for walking on the sandbars to avoid discomfort from shells or coral fragments.
Visiting during high tide when the primary attraction—the sandbars—are submerged and the beach area is significantly reduced.
Avoid walking on or touching the coral reefs; use mineral-based, reef-safe sunscreen to protect the marine ecosystem.
