The provinces, with Rijkswaterstaat for national waters

Bathing season in Netherlands: 1 May – 30 September. Zwemwater.nl and its app show current quality, warnings and swimming advice per official location.

Annual EEA classes do not show temporary bans, short-term pollution or algae alerts. National information last checked 2026-11-01.

Season status: Today (6 November 2026) is outside the official bathing season (1 May – 30 September). Official monitoring is tied to the season (a first sample may be taken shortly before it opens), so there are no current official water-quality results now. The next season starts on 1 May 2027.

How to read this map: Each dot is one official bathing water, coloured by its 2025 rating; select a dot to open that site. The white area is this region; neighbouring regions are shaded. Sea and large lakes are blue, neighbouring countries grey. Positions: official EEA coordinates. Boundaries: Eurostat NUTS 2024, generalised (© EuroGeographics); lakes: Natural Earth. Outlines are simplified, so a few shoreline dots can sit just offshore.
