Brazil, a nation of continental proportions, boasts an expansive and varied geography, characterized by immense river systems that crisscross its landscape. These waterways are integral to the country’s ecosystems, climate, and human settlements. Among the many geographical distinctions one can seek, identifying the easternmost river presents a unique inquiry into the precise contours of Brazil’s Atlantic coastline. This particular distinction highlights a specific point where the land meets the sea at the nation’s furthest eastern reach.
Identifying Brazil’s Easternmost River
The river considered the easternmost in Brazil is the Paraíba River, specifically at its mouth located near Ponta do Seixas in the state of Paraíba. This distinction arises from its geographical coordinates, as its estuary empties into the Atlantic Ocean at approximately 7°09′ South latitude and 34°48′ West longitude. This position places it exceptionally close to Ponta do Seixas, which is recognized as the easternmost point of mainland South America.
The Paraíba River, often referred to as the Paraíba do Norte to differentiate it from other rivers with similar names, flows predominantly through the state of Paraíba. Its course generally runs from west to east, collecting waters from its basin before discharging into the ocean. The river’s journey across the state culminates in this significant easternmost point of outflow.
Its proximity to Ponta do Seixas is what grants it the unique geographical status. While other rivers may be further north or south along the coast, none share the extreme eastern longitude of the Paraíba River’s mouth.
Geographic and Regional Context
The geographical significance of the Paraíba River’s mouth is intrinsically linked to Ponta do Seixas, a promontory that marks the easternmost terrestrial point of the entire Americas. Situated just south of the state capital, João Pessoa, Ponta do Seixas forms a natural landmark. The river’s estuary lies in close proximity to this geographical extreme, making it a prominent feature of the region’s coastal landscape.
The coastal geography around the Paraíba River’s mouth is characterized by a mix of sandy beaches, rocky outcrops, and mangrove ecosystems. This area experiences a tropical climate, with warm temperatures year-round and distinct wet and dry seasons influenced by the Atlantic. The immediate landscape surrounding the river’s final stretch is relatively flat, gradually rising inland.
The Paraíba River holds local importance to the communities living along its banks and near its estuary. Its waters support local ecosystems, including the extensive mangrove forests that act as nurseries for marine life and provide natural coastal protection. Historically, the river has served as a pathway for transportation and a source of sustenance for the region’s inhabitants.
The city of João Pessoa, a significant urban center, is located on the river’s southern bank near its mouth, highlighting the river’s role in human settlement patterns. The river contributes to the region’s natural beauty and economic activities, such as fishing and tourism, which are drawn to the unique coastal environment.

The Paraíba River, often referred to as the Paraíba do Norte to differentiate it from other rivers with similar names, flows predominantly through the state of Paraíba. Its course generally runs from its origin in the Borborema Plateau northeastward to the Atlantic Ocean. The river’s journey across the state culminates in this significant easternmost point of outflow, north of João Pessoa.

The coastal geography around the Paraíba River’s mouth is characterized by a mix of sandy beaches and flat-topped sedimentary deposits, known as “tabuleiros,” which rise sharply above the beaches. This area experiences a tropical climate, with high temperatures and abundant rainfall, particularly from April to June. The region is known for its warm annual temperatures, averaging around 24°C to 26°C (75°F to 79°F).
