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.

During the peak season from June to August, the temperature usually ranges between 22–26°C, making it one of the warmest large water bodies in the country. This creates ideal conditions for both casual bathing and longer swims.
The lake is very popular for recreational swimming, with several designated beaches and gently sloping shores that are suitable for families. Besides swimming, visitors often enjoy water sports such as sailing, windsurfing, and paddleboarding, which the wide surface of the lake allows.
