*** 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
Kamchia Reservoir (Язовир Камчия) shows clear seasonal variation in water temperature. In spring the surface usually ranges from about 6 to 16 °C (≈43 to 61 °F) as the water thaws and sunlight increases. During summer the shallow surface layers commonly warm to roughly 22–26 °C (≈72–79 °F), and in hot spells can reach around 28 °C (≈82 °F), while deeper water remains noticeably cooler. Autumn cooling tends to bring surface temperatures down to roughly 10–20 °C (≈50–68 °F). Through winter the reservoir can approach freezing in parts, typically around 0–4 °C (≈32–39 °F), depending on air temperatures and ice formation. Local conditions, depth, wind and inflow from the Kamchia River all influence these ranges, so temperatures can vary across the reservoir and from year to year.
Swimming at Kamchia Reservoir is generally discouraged and often restricted by local authorities because the body of water serves multiple uses, including water supply, ecological protection and fisheries, and because safety is a concern. Restrictions aim to protect water quality from contamination, preserve habitat and reduce risks from steep banks, sudden depth changes, boat traffic and lack of lifeguards. While people sometimes enter the water informally in warm weather, official rules and signage should be checked and followed, and swimming is safest only where explicitly permitted and supervised.
