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 lakes on the island of Mljet, particularly Veliko and Malo jezero, are among the most remarkable natural attractions of southern Croatia. Due to their enclosed position and connection to the sea through narrow channels, the water in these lakes warms up faster than the open Adriatic. In summer, the temperature often reaches 25–28 °C, sometimes even warmer than the sea itself, which makes them especially inviting for swimming.
Swimming in the Mljet lakes is a unique experience because of their calm waters and stunning natural surroundings. The saltwater lakes are surrounded by dense Mediterranean forest, creating a peaceful and almost lagoon-like atmosphere. Visitors can enjoy not only swimming but also kayaking or leisurely walks along the shores, making the lakes a perfect combination of recreation and relaxation.
