Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
Grevelingenmeer is a large saltwater lake in the southwest Netherlands, located between the islands of Goeree-Overflakkee and Schouwen-Duiveland. Formed as part of the Delta Works, a series of dams and flood protection measures, the lake is fed by the North Sea but is separated from it by a dam. In the summer months, Grevelingenmeer can reach water temperatures of around 18°C to 22°C (64°F to 72°F), making it comfortable for swimming, especially during warm weather. However, it remains a cooler body of water compared to some freshwater lakes, so it’s ideal for those who enjoy refreshing swims.
Swimming is allowed in designated areas around Grevelingenmeer, and it is popular for various water sports, including snorkeling and diving, as the water quality is generally good, and visibility is high. Additionally, Grevelingenmeer has several beaches and recreational zones, such as Brouwersdam, where facilities like restrooms, cafés, and picnic spots make it easier for visitors to spend a full day by the water. For a safer experience, it’s recommended to swim in the designated areas, as some parts of the lake are used for boating and other activities.
