Bathing Water Quality 2026: Beach Rankings

Ethan Hartwell | July 27, 2026

A turquoise sea and a pristine beach don’t always signal safe swimming water. To help vacationers choose where to swim, the Brittany-based association Eau et Rivières de Bretagne publishes the ranking The Beautiful Beach 2026. This map scrutinizes 1,871 sites using microbiological results from the four most recent seasons.

Verdict: more than three out of four beaches are recommended or deemed low risk. However, 423 sites are discouraged or to be avoided. Here are the beaches that come out on top, those that trail at the bottom, and the precautions to take before jumping in.

What to know

  • The 2026 ranking is based on samples collected from 2022 to 2025.
  • 567 sites are “recommended” and 881 are considered “low risk.”
  • 353 beaches are “not recommended” and 70 are classified as “to be avoided.”
  • The ranking does not replace daily health results nor a closure order.

Swimming-water quality: how the 2026 ranking works

France’s regional health agencies monitor swimming waters during the summer season. Depending on the site, 4 to 14 samples are typically taken each year. Two indicator bacteria of fecal pollution are tested: Escherichia coli and intestinal enterococci.

The European ranking combines data from four seasons to assign a quality category of “excellent,” “good,” “sufficient,” or “insufficient.” The Beautiful Beach uses the same public data, but reads it through the lens of the health risk to bathers.

For each beach, the association calculates the share of samples rated as “good” between 2022 and 2025. A score of 100 means all selected samples were good. A score of 90 indicates that 10% were average or poor.

  • Recommended: at least 95% of samples are good and no sample is bad.
  • Low risk: at least 85% of samples are good.
  • Not recommended: at least 70% of samples are good.
  • To be avoided: less than 70% of samples are good.

Beaches ranking 2026: 77% of sites are recommended or low risk

Of the 1,871 sites listed in the 2026 file, 567 are recommended, or 30.3%. The “low risk” category includes 881 beaches, or 47.1% of the total.

Category Number of beaches Share of ranking
Recommended 567 30.3%
Low risk 881 47.1%
Not recommended 353 18.9%
To be avoided 70 3.7%

In total, 77.4% of sites fall into the two most favorable categories. Conversely, nearly one beach in five is not recommended and 3.7% are to be avoided.

Which beaches are the best ranked in 2026?

The Beautiful Beach file lists 23 sites in the top rank, all scoring 100. The Atlantic coast is particularly well represented, but the Mediterranean and Corsica also appear among the best.

The 23 beaches ranked at the top

  • Britanny & Loire-Atlantique: Pen Bron in La Turballe, Pors Carn in Penmarch, Saint-Julien in Plouhinec, Kermabec in Tréguennec, Pool Écluse Pool in Dinard and Treach Salus on Houat Island.
  • Gironde & Landes: Euronat in Grayan-et-l’Hôpital, South Beach and Supersud in Lacanau, Camping Le Roumingue in Lanton, Garonne in Lège-Cer-Ferret, Le Gressier and La Jenny in Le Porge, La Lagune in La Teste-de-Buch, Saint-Nicolas in Le Verdon-sur-Mer and Central Beach in Vielle-Saint-Girons.
  • Mediterranean: Étang des Ayguades in Gruissan, Port-Leucate Les Carats in Leucate, Carnon-Les Dunes in Mauguio, Rive Gauche-Saint-Roch in Palavas-les-Flots and Mimosa-Les Montilles in Vendres.
  • Corsica: Negro in Olmeta-di-Capocorso and Chez Theresa in San-Giuliano.

A perfect score does not mean that no occasional pollution can occur. It indicates that all samples considered in the calculation were rated good.

The ten beaches at the bottom of the 2026 ranking

On the opposite end of the list, these ten sites have the lowest scores. They all belong to the “to be avoided” category of The Beautiful Beach.

  1. Boulogne Centre Beach, Boulogne-sur-Mer: 37.5 out of 100.
  2. Cousteau, Saint-Laurent-du-Var: 38.9 out of 100.
  3. Les Flots Bleus, Saint-Laurent-du-Var: 40.8 out of 100.
  4. Plage du Courant, Mimizan: 42.9 out of 100.
  5. Le Portel Centre Beach, Le Portel: 46.7 out of 100.
  6. Château, Landunvez: 50 out of 100.
  7. Illien, Ploumoguer: 52.4 out of 100.
  8. Lerret, Kerlouan: 53.8 out of 100.
  9. Toul an Ouch, Plougoulm: 54.4 out of 100.
  10. La Brèche, Tracy-sur-Mer: 56.5 out of 100.
Caution
A beach classified as “to be avoided” by the association is not necessarily administratively closed. This category reflects the frequency of average or poor results across four seasons. Before swimming, check the local display and the latest analyses available.

Why can the European ranking give a different result?

A beach can be rated “excellent” by the European ranking while being less well-rated by The Beautiful Beach. It isn’t necessarily an error. Both indicators use the same analyses, but they do not answer exactly the same question.

The European grid measures the average microbiological quality and makes it easier to compare across countries. The Beautiful Beach, for its part, counts the share of samples that pose no notable risk according to the health thresholds used. Its reading is therefore more straightforward, but also more demanding.

Another important difference: the association keeps samples indicating short-term pollution. It excludes confirmatory analyses conducted to verify that a pollution episode has ended.

Rain, sanitation: why water quality can change quickly

Microbiological pollution of swimming waters is mainly fecal in origin. It can come from a failing sanitation network, a sewer overflow, agricultural runoff, or an accidental discharge.

After a storm or heavy rainfall, networks can become saturated. Runoff water also carries contaminants to rivers, then to the sea. A beach normally well rated can thus experience a temporary decline in quality.

Contaminated water can cause stomach upsets, ear infections, or conjunctivitis. Young children, the elderly, and people with weakened immune systems should exercise extra caution.

The La Belle Plage map helps plan vacations with a factor that is often invisible: the consistency of the water’s sanitary quality. This sensible step should be complemented on the day of swimming by local information.
