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 Stymphalia (Λίμνη Στυμφαλία) is a shallow, seasonally variable wetland in the northern Peloponnese, so its surface temperatures change noticeably through the year. In winter months the water typically falls to around 5–10 °C (41–50 °F), depending on local cold snaps and water depth. Spring sees a steady rise, often reaching 10–18 °C (50–64 °F) as days lengthen and inflows increase. Peak summer temperatures usually range from about 18–24 °C (64–75 °F) in warm years, though shallower bays can warm more quickly; autumn cooling follows a similar decline back toward spring values. Local conditions, rainfall and water level fluctuations make exact figures variable from year to year.
Swimming in Lake Stymphalia is generally discouraged and often restricted because the lake is a protected wetland and important bird and amphibian habitat. The shoreline is reed‑fringed and the bottom can be muddy and uneven, creating safety and hygiene concerns, while conservation rules aim to minimise disturbance. Visitors should respect signage and local regulations; while spontaneous wading by locals may occur, organised bathing is not promoted, and those seeking reliable swimming conditions will usually opt for nearby managed freshwater sites or coastal beaches.
