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 Varna (Варненско езеро) is a shallow, brackish lagoon adjacent to the city of Varna on the Bulgarian Black Sea coast, and its water temperatures fluctuate noticeably through the year. In winter the lake can cool to near freezing, typically around 0–6 °C (32–43 °F), while spring brings a gradual rise to roughly 6–15 °C (43–59 °F). During the warmest months of summer surface temperatures commonly reach about 22–28 °C (72–82 °F), though sheltered shallows may be a few degrees warmer. In autumn the lake cools again, with temperatures generally falling into the 12–20 °C (54–68 °F) range. Actual values depend on recent weather, wind, depth and connection to the sea, so seasonal ranges are indicative rather than exact.
Swimming in Lake Varna is possible and is practiced locally, especially in summer when temperatures become comfortable for bathing. Whether and where swimming is allowed depends on local regulation and water-quality monitoring; designated recreational areas and marinas are the usual places for safe bathing because authorities test for pollution and manage access. Some parts of the lake have muddy bottoms, aquatic vegetation or contamination risks and are less suitable for swimming. For safety and hygiene it is advisable to use approved beaches or public sites where water quality is regularly checked.
