*** 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
Ioannina (Ιωάννινα) sits beside Lake Pamvotida, a relatively shallow lake that warms and cools noticeably through the year. Typical surface temperatures range from roughly 4–8 °C (39–46 °F) in winter, rise to about 8–16 °C (46–61 °F) in spring, reach commonly 20–26 °C (68–79 °F) in summer, and fall back to around 12–18 °C (54–64 °F) in autumn. Because the lake is not very deep and has sheltered bays, summer surface temperatures can be comfortable for bathing in the warmest weeks, while early and late season waters remain brisk.
Swimming in the lake is practiced locally and is not universally prohibited, but opportunities depend on spot, season and current water quality. There are no extensive staffed public beaches around the city, so people generally swim from accessible banks and small piers; authorities may issue temporary advisories when pollution, algal blooms or other hazards are detected. In addition to water-quality considerations, submerged vegetation and uneven bottoms mean swimmers should be cautious. Visitors planning to swim should check recent local information and signage, choose well-known entry points, and avoid the lake when official warnings are in effect.
