*** 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
The water temperature in and around the Malko Sharkovo Reservoir follows a typical temperate seasonal pattern. In winter the surface temperatures commonly hover close to freezing, about 0–5 °C (32–41 °F). During spring the reservoir warms to roughly 6–15 °C (43–59 °F) as air temperatures rise and runoff decreases. By summer, shallow bays and surface layers can reach 18–26 °C (64–79 °F), and on hot late-summer days localized spots may climb toward 28 °C (82 °F). In autumn the water cools again to approximately 10–18 °C (50–64 °F). Actual temperatures vary with depth, wind, shading and recent weather, with deeper water remaining significantly colder than surface readings even in midsummer.
Swimming opportunities depend on local rules and conditions rather than the reservoir’s inherent suitability. In many Bulgarian reservoirs, swimming is possible during the warm months but may be restricted near infrastructure, intakes or where the body of water serves as drinking-water storage or irrigation. Safety concerns—cold deep water, sudden drop-offs, submerged obstacles and the absence of lifeguards—are common reasons for prohibitions or unofficial avoidance. Before entering the water at Malko Sharkovo, visitors should check local signage and municipal guidance, consider water quality and currents, and swim only in designated or commonly used areas at their own risk.
