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 Kournas (Λίμνη Κουρνά) is Crete’s only natural freshwater lake and, being relatively shallow, its temperature responds quickly to seasonal changes. In summer months (June–August) surface water typically warms to about 22–28 °C (72–82 °F), with the warmest periods sometimes reaching the upper part of that range. Late spring and early autumn (May, September) usually see temperatures around 18–24 °C (64–75 °F). In winter (December–February) the lake cools to roughly 10–16 °C (50–61 °F), while early spring often falls between 12–18 °C (54–64 °F). These figures are approximate and can vary year to year depending on rainfall and air temperatures.
Swimming in Lake Kournas is generally permitted and popular in the warmer months because the freshwater and relatively calm conditions make it inviting for bathers. Local facilities and small beaches support recreational use, and some visitors also rent pedal boats, so swimmers should be mindful of craft and marked areas. In colder months swimming is uncommon due to low temperatures and local advisories may discourage it; additionally, observers should respect any posted signs or protected-area rules aimed at preserving the lake’s ecology. As with any natural site, checking current local guidance and water conditions before entering is recommended.
