Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 65°F (18°C) to 68°F (20°C). This is already quite warm water, which is ideal for most people. Swimming becomes comfortable, and prolonged stays in the water do not cause discomfort. This temperature is perfect for family trips and for those who prefer warmer water. It is also comfortable for water sports such as surfing or swimming. 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.

*** 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
Lake Koroneia (Λίμνη Κορώνεια) in Central Macedonia is a shallow, historically eutrophic lake whose surface water temperatures vary markedly with the seasons. In winter the lake commonly cools to around 0–6 °C (32–43 °F), while spring sees a rise to roughly 8–16 °C (46–61 °F). By summer, particularly during heat waves, surface temperatures often reach 20–30 °C (68–86 °F) or occasionally slightly higher in very shallow bays. In autumn the water typically cools again to about 10–20 °C (50–68 °F). These ranges are indicative of surface temperatures; deeper or shaded areas may be cooler, and sudden weather changes can alter readings quickly.
Swimming is generally discouraged and in some cases effectively restricted around Lake Koroneia because of ecological and public‑health concerns. Decades of nutrient enrichment, periodic algal blooms, agricultural and urban runoff, and episodes of very low water levels have degraded water quality and habitat, prompting conservation and restoration measures. While informal bathing has occurred locally, authorities and conservation bodies advise caution and recommend checking current local guidance before entering the water, both to protect human health and to support ongoing environmental recovery efforts.
