*** 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
Black Lake (Črno jezero) in Slovenia is a mountain lake lying at an altitude of over 1300 meters. Because of its height and location in a shaded forested area, the water here stays cold throughout most of the year. In summer, surface temperatures can briefly reach 15–18°C, but the water is usually cooler, especially below the top layer. Outside the warmest months, it often remains below 10°C.
Swimming in Black Lake is technically possible, but it is not a typical bathing spot. The lake is shallow, peat-colored, and surrounded by protected nature, so most visitors come for hiking and views rather than for swimming. Those who do take a dip should be ready for very refreshing water and only short stays in it.
