*** 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
Sofia (Bulgarian: София) is close to a few freshwater bodies, the most used for recreation being Pancharevo Lake (Pancharevsko ezero) on the city’s outskirts. Water temperatures there follow a temperate continental pattern: in winter the surface typically falls to about 0–4 °C (32–39 °F), in spring it rises from roughly 6–16 °C (43–61 °F), in summer it commonly reaches 18–26 °C (64–79 °F) with the warmest weeks occasionally pushing a bit higher, and in autumn it cools back to around 10–18 °C (50–64 °F). Exact temperatures vary year to year with air temperature, rainfall and wind, and shallower bays warm faster than deeper areas.
Swimming is commonly practised in summer at Pancharevo and some other recreational spots near Sofia because these areas are intended for leisure and accessible from the city. However, swimming rules differ by site: certain reservoirs around Sofia are prohibited from bathing because they serve as drinking-water sources or for safety and boating activities, and lifeguards are not always present. Local signage and municipal guidance should be checked before entering the water.
