Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 60°F (15°C) to 65°F (18°C). The water is comfortable for most people, making it an ideal range for water sports enthusiasts. The temperature does not cause significant discomfort, and swimming will be pleasant for the majority. However, it's important to remember that prolonged exposure to the water can still lead to cooling, so it's essential to monitor the time spent in the water, especially for children or elderly people. 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
Piedmont Lake in eastern Ohio experiences typical temperate-lake seasonal changes in surface water temperature. In winter the surface commonly falls close to freezing, roughly 32–40°F (0–4°C). Spring warming brings surface temperatures into the 40–60°F (4–15°C) range as ice melts and the water column mixes. During summer the shallows and nearshore areas usually warm most, often reaching about 70–80°F (21–27°C) on typical hot days and occasionally climbing into the low- to mid-80s°F (27–30°C) during heat waves. In autumn the surface cools again to roughly 50–65°F (10–18°C) before winter stratification breaks down. Deeper water remains colder year-round and changes more slowly than the surface values given.
Swimming at Piedmont Lake is generally allowed because the reservoir is managed for multiple recreational uses, including boating, fishing and public access for water contact activities. However, access and specific swimming areas may be limited by shoreline conditions, posted rules, seasonal water-quality advisories or the absence of lifeguards, so conditions can vary. Swimmers should be mindful of cold-water shock in early spring or late fall, watch for algae or debris advisories in summer, and follow any posted signage or local guidance for safe swimming.
