Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. 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.

Location & Local Information
Pernik sits near the Studena Reservoir, the main lake-like body of water associated with the town. Water temperatures there vary with the seasons and the reservoir’s elevation, typically ranging in spring from about 5–15 °C (41–59 °F) as the water slowly warms after winter. In summer, surface temperatures in sheltered bays and shallow areas commonly reach roughly 18–25 °C (64–77 °F), though deeper parts remain cooler. Autumn temperatures fall back to roughly 8–16 °C (46–61 °F) as cooling sets in, and in winter the reservoir can approach near-freezing conditions, around 0–4 °C (32–39 °F), depending on cold spells and ice cover.
Swimming at the Studena Reservoir is generally restricted because it serves as a source of drinking water and because of safety concerns like steep banks, submerged hazards and variable depths. For those reasons local authorities typically prohibit or limit organized bathing and water sports; nevertheless, informal swimming sometimes occurs in warmer months in shallow inlets. Visitors should pay attention to posted signs and local regulations: permitted recreational use is usually focused on designated areas and activities that protect water quality and public safety.
