Praia de Macapá is a 1.3-kilometer stretch of golden and white sand beach located at the mouth of the Camurupim River estuary in Piauí, Brazil, near the settlement of Macapá. The beach provides direct, open access to the South Atlantic Ocean and is characterized by a shallow turquoise lagoon and a landscape of shifting dunes. The beach is adjacent to a road, and public parking is available nearby, with some properties offering free parking for guests. The water entry slope is gradual, and the depth increases slowly, making for a manageable carry from beachside parking or amenities to the water's edge. The area is a renowned destination for wind sports, with consistent and strong winds, particularly favorable for kiteboarding and windsurfing; wind statistics indicate frequent speeds around 8-9 m/s with significant gusts. This consistent wind exposure means paddlers, especially on stand-up paddleboards or kayaks, should be prepared for potential chop and wind-driven current, especially on open water outside the more protected estuary area.

The beach's character is defined by its transformation with the tides, as the estuary meets the sea, creating a dynamic environment. The vibe is relaxed and quiet, with a rustic fishing village atmosphere. Basic amenities for visitors include showers, restrooms, changing cabins, and sunbed rentals. Several cafes and restaurants are within walking distance. The water is warm year-round, with the hottest monthly average air temperature reaching 36.3°C in September and water temperatures peaking around 29.2°C; the coolest month is March, with air around 28.9°C and water at 29°C, allowing for comfortable paddling in all seasons. From this launch point, paddlers can explore the unique estuary where the river meets the ocean, cruise along the coastline, or navigate the shallow, glassy waters of the lagoon, particularly during calmer morning conditions before the prevailing winds strengthen.
