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.

Location & Local Information

The Reka River is one of the most distinctive rivers in Slovenia, flowing through the karst region and disappearing underground into the famous Škocjan Caves. Its waters are influenced by rainfall and karst springs, which means the temperature can vary, but it generally stays on the cooler side, often between 12°C and 18°C during the warmer months. Because of this, swimming in the river is refreshing but rarely becomes a widespread activity.

There are a few calmer stretches where locals sometimes take a dip on hot days, but the Reka is better known for its dramatic underground course and natural beauty than for bathing. The flow can change quickly after rain, so swimming is not always safe. For most people, the river is a place to admire, hike along, and enjoy nature, rather than a typical swimming spot.
