Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature is above 82°F (28°C). This is very warm water, which may feel almost hot to most people. Swimming in such conditions is perfect for those seeking relaxation and comfort in the water. These waters are often preferred for relaxation in hot weather, as the water temperature does not cool the body significantly. However, it is important to remember that in such warm waters, caution is necessary, as prolonged exposure without rest can lead to overheating. 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.

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 Vouliagmeni (Λίμνη Βουλιαγμένης) is a small thermal coastal lake near Athens fed by underground springs, so its water temperature is notably mild compared with open sea waters. Typical year‑round temperatures are roughly 22–29 °C (72–84 °F), with the lower end usually recorded in late winter and early spring and the higher end reached in summer. Seasonal variation is therefore modest: winter values can be around 20–22 °C (68–72 °F), spring and autumn commonly 22–26 °C (72–79 °F), and summer often climbs to 26–29 °C (79–84 °F), depending on weather and spring flow.
Swimming is permitted and the lake is a popular spot precisely because of the comfortably warm, mineral‑rich water and its sheltered setting. Access is managed for safety and conservation, with lifeguards and facilities on site and limits on visitor numbers to protect the fragile ecosystem. Visitors are normally allowed to bathe in designated areas but must follow site rules to avoid disturbing the lake’s geology and biology. The combination of relatively steady, warm temperatures and controlled access makes Lake Vouliagmeni appealing for year‑round swimming, physical therapy and relaxation, while its protected status explains ongoing restrictions and management.
