Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 54°F (12°C) to 60°F (15°C). The water is significantly warmer, and swimming becomes possible for most people. However, caution may still be required for prolonged stays in the water, as extended exposure can cause discomfort. This is a suitable temperature range for short swims and for those accustomed to cooler water. For more comfortable swimming, it is recommended to use proper gear. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** Forecast - Our water temperature forecast
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.

The Yser River, which flows through both France and Belgium, offers limited but pleasant opportunities for swimming, especially during the warmer months. In summer, the water temperature typically ranges from 16-20°C (61-68°F), which can be comfortable for swimming in calmer sections of the river. The Yser tends to be slow-flowing in many areas, making it safer for swimming, particularly in designated swimming zones or quieter stretches. However, the river's water quality can fluctuate due to agricultural runoff or local pollution, so it’s important to check water conditions before swimming. In colder months, the water temperature can drop significantly, making swimming less enjoyable or even unsafe.
