*** Forecast - Our water temperature forecast

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

Alexandreia (Αλεξάνδρεια) in Central Macedonia sits near a small lake whose temperatures follow the region’s continental-Mediterranean climate. Typical surface water temperatures in winter are commonly in the range of about 4–10 °C (39–50 °F). In spring they usually rise to roughly 10–20 °C (50–68 °F) as air temperatures warm. Summer surface temperatures often reach about 20–27 °C (68–81 °F) on warm days, while autumn brings a cooling trend to approximately 12–18 °C (54–64 °F). These figures are approximate and can vary year to year with weather, depth, inflows, and wind-driven mixing; shallow areas warm and cool more rapidly than deeper sections.

Swimming in the lake is practiced at times by locals, but it is not always formally organized or supervised. Whether bathing is permitted depends on municipal regulations, current water quality, and the lake’s uses (e.g., irrigation, fisheries, or flood control), so access may be restricted for safety or environmental reasons. Water temperature affects comfort and safety—summer temperatures around or above 20 °C (68 °F) are generally comfortable for swimming, while cooler conditions increase hypothermia risk. Visitors should follow posted signs, check with local authorities about seasonal water quality and permitted activities, and take standard precautions if entering the water.
