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

Comarnic (in Romanian: Comarnic) is a small town in South‑Muntenia, Romania, located along the Prahova Valley with a number of small lakes and reservoirs in the surrounding area. Water temperatures in these inland bodies of water follow regional seasonal patterns: in winter (December–February) surface temperatures commonly sit near freezing, about 0–4 °C (32–39 °F); spring (March–May) sees a rise to roughly 5–15 °C (41–59 °F); summer (June–August) is when lakes are warmest, typically around 18–24 °C (64–75 °F) on average; and autumn (September–November) cools back to approximately 10–16 °C (50–61 °F). Exact values vary with depth, sunlight, recent weather and whether the water body is fed by cold mountain streams.

Swimming in and around Comarnic is possible during the warmer months when surface temperatures are comfortable, but it is not uniformly supervised or officially designated at all sites. Some reservoirs or privately managed lakes may restrict access for safety, water‑supply or ecological reasons, and water quality can fluctuate after heavy rains. Visitors should observe local signage, check municipal rules and water‑quality information where available, and take ordinary precautions—no swimming where prohibited, avoid strong currents, and be aware that colder spring and autumn temperatures can present hypothermia risk even when air temperatures feel mild.
