*** 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
Petroșani, located in the Jiu Valley of western Romania, is surrounded by small lakes and reservoirs that reflect mountain and valley conditions. Water temperatures in these bodies of water vary with the seasons: winter surface temperatures commonly hover around 0–4 °C (32–39 °F) and many smaller lakes can freeze over; spring generally sees 4–12 °C (39–54 °F) as meltwater cools the basins; summer brings the warmest conditions, with surface temperatures typically in the 12–22 °C range (54–72 °F), though shallow areas may warm a few degrees higher on hot spells; autumn cooling returns temperatures to roughly 6–14 °C (43–57 °F). Deeper or shaded reservoirs remain noticeably colder than shallow ponds even in midsummer.
Swimming opportunities depend on the specific lake and local regulations; some designated recreation areas permit swimming in summer when water quality and safety measures are in place, but many mountain and reservoir sites around Petroșani are unofficial and lack lifeguards, marked bathing zones, or monitoring. Historical mining activity and variable runoff can affect water quality in parts of the region, and reservoir operations may pose hazards such as sudden water level changes. For these reasons swimming is sometimes possible but should only be undertaken where signage and local authorities indicate it is allowed and safe.
