Fifth in Europe

Luxembourg has no coastline. It has no Mediterranean beaches, no Atlantic surf, no North Sea shallows. It has rivers, lakes, and outdoor pools. And according to the latest annual assessment published Friday by the European Environment Agency and the European Commission, 94.1% of its bathing waters are rated excellent, the highest standard set by the European Union.[1]

That puts Luxembourg fifth in Europe, behind Austria, Bulgaria, Cyprus, and Greece, where at least 95% of sites received the top rating. Germany follows in seventh. France sits further back in twenty-first. Belgium ranks twenty-fourth, with 67.9% of its sites achieving the top classification.[2]

The report covers more than 22'200 bathing sites across all EU Member States, plus Albania and Switzerland, monitored during the 2025 season. Overall, 85% of European bathing waters achieved the excellent rating. 96% met at least the minimum quality requirements. Only 1.5% were classified as poor.[3]

Coastal waters continue to outperform inland ones. 88% of marine bathing areas were rated excellent, compared to 78% of rivers and lakes. This is where Luxembourg's ranking becomes more interesting: it is an entirely inland country, competing in the harder category, and still placing fifth overall.[4]

The assessment focuses on bacteria capable of causing serious illnesses, primarily intestinal enterococci and Escherichia coli. The testing regime is defined by the EU's Bathing Water Directive, which sets minimum standards for monitoring, management, and public information. Sites are classified as excellent, good, sufficient, or poor based on percentile calculations over four seasons of data. A site rated poor for five consecutive years must be closed or have bathing permanently discouraged.[5]

The results reflect decades of investment. The Bathing Water Directive, first adopted in 1975 and substantially revised in 2006, has driven improvements in urban wastewater treatment, residual water collection, and the tracking of harmful algal blooms. Areas that were once heavily polluted, including some in urban settings, are now safe for swimming. EEA Executive Director Leena Yla-Mononen noted that Europeans can now enjoy some of the world's highest bathing water standards as a result of solid implementation of EU rules.[6]

The European Commission cautions that protecting water resources remains an ongoing challenge. Chemical pollution, biodiversity loss, and the effects of climate change all threaten the progress achieved. The EU Water Resilience Strategy, presented as part of the broader European agenda, aims to address these pressures through improved water governance, nature-based solutions, and reduced pollution at source.[7]

For Luxembourg, a landlocked country of fewer than 700'000 people, ranking fifth in Europe for water quality is not a minor achievement. It is the result of sustained policy effort, infrastructure investment, and monitoring across a network of sites that most Europeans will never visit. The Moselle, the Sure, the Our, the Alzette, and the many smaller rivers and lakes that cross the country are cleaner than they have been in decades. They are also, according to the data, cleaner than most of the coastline of France, Belgium, and Germany combined.

The EEA has published an interactive map where swimmers can check the quality of individual bathing sites across Europe. If you are in Luxembourg this summer and looking for a place to swim, the odds are in your favour.[8]
