Water Temperature: Daily Trends, Historical Records, and Forecast
✅ As of today, the minimum water temperature ranges from 68°F (20°C) to 74°F (23°C). The water is warm and pleasant for swimming, and in this range, one can stay in the water for extended periods without the risk of hypothermia. This is the ideal temperature for relaxation, swimming, and water sports. Families with children, as well as outdoor enthusiasts, will enjoy swimming and time spent in the water. For most people, this is the optimal temperature for a comfortable beach experience. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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.

The Lom River (река Лом) in northwestern Bulgaria, joining the Danube at the town of Lom, shows typical temperate-river seasonal temperature behavior. In winter the water is cold, commonly around 0–4 °C (32–39 °F). Spring brings a steady rise as snowmelt and warming air push temperatures into roughly 4–12 °C (39–54 °F). Summer sees the warmest conditions, especially in shallow stretches and slow-moving backwaters, with typical surface temperatures in the neighborhood of 18–25 °C (64–77 °F). In autumn the river cools again to about 10–16 °C (50–61 °F) as air temperatures fall and flow increases. Local conditions such as depth, shading, recent weather and inflows can shift these ranges by several degrees.
Swimming along the Lom is possible in some places, but it is not universally recommended or officially sanctioned throughout the urban and port sections. Factors limiting safe bathing include strong currents in the main channel, boat and commercial traffic near the confluence with the Danube, variable water quality and lack of lifeguards or marked bathing areas. Where locals do swim, they tend to choose calmer side arms or cleaner rural stretches outside the port zone; anyone considering entering the river should check current local advisories, signage and visible water quality before doing so.
