The beach is part of a delicate dune ecosystem that acts as a natural buffer against coastal erosion.
The São Jacinto Dunes Natural Reserve, located immediately adjacent to the beach, contains unique flora adapted to salt-spray and sandy soil.
The peninsula is one of the narrowest points of the Portuguese coast, flanked on one side by the Atlantic and on the other by the Ria de Aveiro estuary.
The water temperature in this region remains relatively low throughout the year due to the prevailing North Atlantic currents.
The beach area is managed as part of a sensitive environmental conservation zone to protect native dune vegetation.
São Jacinto Beach is a rugged, expansive coastal stretch located on a narrow peninsula separating the Atlantic Ocean from the Aveiro Lagoon. The landscape is dominated by extensive, protected dune systems that provide a natural barrier between the Atlantic waters and the town. Unlike the urbanized beaches of nearby Costa Nova, this area is characterized by its wild, untamed environment and lack of high-density construction. The beach serves as a protected gateway to the São Jacinto Dunes Natural Reserve. The shoreline is known for strong currents and significant wave action, making it a common destination for experienced surfers rather than casual swimmers. Access to the beach requires crossing from the Aveiro mainland via a ferry or driving around the lagoon perimeter.

Bring a windbreaker or protective clothing, as the exposed location leads to constant, strong ocean breezes.
Wear footwear suitable for walking on shifting, deep sand dunes.
Always swim near designated lifeguard stations during the summer months due to powerful rip currents.
Attempting to swim outside of supervised zones or during red-flag conditions, as the sea here is notoriously dangerous for inexperienced swimmers.
Lifeguard services are only active during the peak summer bathing season.
Stay strictly on designated wooden walkways to avoid damaging protected dune vegetation; littering is strictly prohibited in the nature reserve area.
