Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 47°F (8°C) to 50°F (10°C). This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing can be used. 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.

Location & Local Information
Cēsis, known in Latvian as Cēsis, sits among wooded hills and is home to a modest lake often used for recreation. Seasonal surface temperatures typically range from just above freezing in winter to pleasantly warm in summer: winter months commonly see water near 0 °C (32 °F) when ice forms; spring temperatures rise to roughly 4–12 °C (39–54 °F); summer brings the warmest conditions, often between 16–24 °C (61–75 °F) with occasional peaks slightly higher in calm, sunny spells; autumn cooling usually puts the lake around 8–14 °C (46–57 °F). These values depend on weather, depth and wind, so local daily readings can vary.
Swimming is generally allowed and is popular at designated bathing spots during the summer because temperatures then reach comfortable ranges and authorities monitor water quality. Lifeguards or marked bathing areas may be present in high season, while unsupervised swimming outside these zones remains a personal responsibility. In winter, the lake frequently freezes and ice swimming or plunges are practiced by some, but such activity is only safe where ice thickness and local rules permit. Cold water poses hypothermia risks below about 10 °C (50 °F), so visitors should follow posted guidance, check conditions and take appropriate precautions.
