Póvoa de Varzim beaches
The beaches in Póvoa de Varzim are an extensive and continuous group of golden sandy beaches forming small bays or coves along the shoreline in northern Portugal. These do not have any barrier and are in fact a single beach, over 12 km long, under the name Praia da Póvoa de Varzim (Póvoa de Varzim Beach). Division may be arbitrary and serve localization porpoises.

Historically, the waterfront has been used for trading, fish industry, health and leisure since remote periods. The fish industry in Póvoa de Varzim developed during the Roman Empire and is one of the earliest tourist areas in Portugal attracting visitors since early 18th century. Some of its beaches are rich in marine life. In 2016, all its coastline were blue flag beaches, including all the urban area from Cape Santo André to the seaport. Most of these also meet criteria under "Praia com Qualidade de Ouro" (Gold Quality Beach) attributed by the Portuguese environmental organization Quercus, which is based in stricter criteria, including excellent water quality for five years in a row and better-scoring microbiological tests than those defined by the EU.

Beaches (called Praia in Portuguese) are managed by traditional Povoan families, known as Banheiros who are descendant of fishermen who left fishing for this business some generations ago. These families often exhibit their Siglas poveiras family mark in their belongings, in the same way as the fishermen did. Although most fishermen stopped using family marks, the Banheiros kept the tradition live to the present day.

History
In the beginning of the 18th century, Benedictine monks walked distances to take the "Baths of Póvoa", in search of iodine, considered invigorating, and cures for skin and bones problems throw sea and sun-baths. These monks were attracted by the large amounts of algae that ends up in the local beaches from the sheltered bay to Cape Santo André. By the 19th century, the popularity increased with people from the provinces of Minho, Trás-os-Montes and Alto Douro that arrived by medical advice to cure several health problems, by breathing the air and diving in the rich iodine seawaters of Póvoa, in a popular movement that occurred in the European Atlantic coast since the 18th century.

During the Belle Epoque, this popularity is especially noticeable among the wealthiest classes and, especially, between the Portuguese-Brazilians (the Brasileiros). Several hotels, theaters and casinos opened. It then became the most popular holiday destination in Northern Portugal, Between the 1930s and the 1960s, beach-going became a popular holiday destination for the masses.

Beach variation

Fine sand vs medium sand
The Northwestern coast beaches are different from those in the southwestern. The south beaches are sided by the urban area, have medium sand, occasionally fine, and with granitic gneiss outcrops. The Northern ones have fine sand, occasionally with cobble in the swash zone, with little to no rocky outcrops and the area is completely dominated by sand dunes and rural.

Dissipative and reflective beaches
The southern beaches tend to be reflective beaches, and the northern ones are dissipative beaches, and there's transition between both types around the cape of Santo André.

Microclimate
The microclimate is also distinct. The southern ones have low diurnal temperature variation, just , while the Northern ones almost double that figure. in the South rainfall is significantly lower, solar irradiation higher and wind gusts from the prevailing northern winds are stronger. Yet, because of the fine sand of the Northern ones, these are more prone to sand blowing and dune transformation and evolution, the southern sands are not.

sand dunes

The Northwestern coast is completely dominated by the Dune system of Póvoa de Varzim, most of the foredunes are dynamic. There are dune recovery projects by the Portuguese Agency of the Environment, the Agência Portuguesa do Ambiente in areas where human activity was disruptive, including rehabitation of foredunes, using dune regenerators and grey dune preservation. Some foredunes suffered from Coastal erosion and, in an area, it was necessary to use sandbags to save it from collapsing.

The grey dunes ecosystems suffered significant damage due to human activity, agriculture or housing. The remaining sites are protected: including the Rio Alto grey dunes, near the estuary of Rio Alto in the civil parish of Estela, and Barranha grey dunes, in Aguçadoura, the late is open for visitation using boardwalks.

Rock pooling

The southwestern coast is dominated by a rich marine ecosystem forming natural reefs, these are rich in a diversity of marine life in distinct niches. These reefs and tide pools are supported by the granitic gneiss, the base for these reefs. The Póvoa de Varzim Maritime Police patrols Póvoa de Varzim seafront, including the seaport, beaches and maritime waters under the national sovereignty and jurisdiction. It often acts against smuggling, illegal fisheries, and unruly harvest of shellfish in these beaches.

In Póvoa de Varzim there are subtropical and temperate fish species. Tide pools often only exist as separate entities only at low tide and are habitats of diverse adaptable animals and algae. The most common fish in tide pools are blennies (generally called marachomba), including: Parablennius gattorugine, Parablennius pilicornis, Coryphoblennius galerita, Lipophrys pholis, and Lipophrys trigloides. Other small fish recorded locally include worm pipefish, rock gobies and snail-fish. In larger tide pools, schools of juvenile sargo seabreams, Zebra seabreams, small-headed clingfish, brilliantly coloured and camouflaged wrasses such as the green wrasse, the Common Wrasse and the Ballan Wrasse, rocklings and juveniles of other species of fish are frequently found.

Hermit crabs such as Pagurus bernhardus, Clibanarius erythropus and more rarely Pagurus cuanensis can be found in specific beaches, along with crabs such as Pilumnus hirtellus, Pachygrapsus marmoratus, Xantho hydrophilus, Carcinus maenas, Necora puber, the filter-feeding crab Porcellana platycheles and a number of other species. There are abundant populations of shrimp of the species Palaemon serratus, Palaemon elegans, Lysmata seticaudata and Hippolyte varians.

The most regular species of anemones are:  Actinia fragacea, Aulactinia verrucosa, diverse varieties of Actinia equina, Anemonia viridis, Actinothoe spirodeta and Cereus pedunculatus. The giant Marthasterias glacialis is the most sighted starfish, but other smaller species do exist such as purple Asterias rubens, the tiny Asterina gibbosa and the exotic-looking Ophiothrix fragilis brittle star. Paracentrotus lividus is the general urchin locally and has diverse colour varieties including purple, green and pink.

Molluscs commonly found at the local beaches includes the Octopus vulgaris and the opisthobranch gastropods Aplysia fasciata and Aplysia punctata, nudibranchs, and chitons. Other common snails are Patella vulgata, Patella pellucida, Gibbula umbilicalis, Osilinus lineatus, Littorina littorea, Trivia monacha, the predator snails Nucella lapillus and Ocenebra erinacea, the scavenger snails Nassarius reticulatus and Nassarius incrassatus. Two types of mussels often occur, including the extremely common Mytilus edulis and the rarer Modiolus barbatus, along with several other species of bivalves.

Surfing beaches
Póvoa de Varzim diversity of beaches provide quality surf spots and distinct surfing experiences in very short distance: along the dissipative beaches of the Northwestern coast, protected by sand dunes in the countryside, or along the southwestern reflective beaches of the city center.

The northern ones are excellent for experienced surfers, have rip currents that add to the surfer experience, functioning as a fast transit, or elevator, between the beach and the waves. However, these are not suitable for novice surfers and may be hazardous to inexperienced swimmers. it is a very large area, where surfing can be done during high or low tide, with swells from northwest to Southwest, with consistent waves that break in the beach without conditioning factors.

In the southern coast, Salgueira Beach is a reflective Beach with swells from Northwest to southwest, with rocky outcrops and people as conditioning factors with a small take-off area in the middle of the beach. In the past, the local surfer community did not allowed beginners or outsiders to use this spot, known as localism in surf culture.
