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
Lake Črnava (Črnava) is a small natural lake in Slovenia, located in a quiet, forested area. Because of its modest size and relatively shallow depth, the water warms up moderately during the summer. In the warmest months, from June to August, surface temperatures usually reach 20–24°C, making swimming comfortable for visitors. In spring and autumn, the water is cooler, typically between 12–16°C, while in winter it can drop to around 4–6°C.
Swimming in Lake Črnava is possible and enjoyed mainly during summer. The lake offers calm water and a natural setting, which makes it ideal for families and those seeking a quiet spot for relaxation. Unlike larger recreational lakes, it is less crowded, giving swimmers more space and a peaceful environment.
Outside of the summer months, swimming is less common due to the cooler water, but the lake remains attractive for walking, picnics, and nature observation. Even a brief dip in late spring or early autumn can be refreshing, though the water feels noticeably cool.
