*** 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
Madison Lake, a small inland reservoir in Ohio, follows the typical seasonal pattern for Midwestern shallow lakes. In winter the surface approaches freezing, roughly 32–39°F (0–4°C), and ice cover is common during sustained cold spells. Spring sees a steady warm-up, with surface temperatures usually between about 40–65°F (4–18°C) as ice melts and the water mixes. Peak summer surface temperatures most often range from the mid-70s to mid-80s °F, roughly 24–29°C, especially on warm, sunny stretches; deeper pockets, if present, stay a few degrees cooler. In autumn the lake generally cools from around 50–70°F (10–21°C) until ice returns, with temperatures varying by weather and wind-driven mixing.
Swimming at Madison Lake is generally allowed in areas designated by local park authorities when conditions are safe and water-quality tests permit. Summer is the main swimming season because surface temperatures are usually comfortable, but managers may close access if there are harmful algal blooms, high bacterial counts, strong currents, or hazardous weather. Lifeguard coverage is not guaranteed at every site, so swimmers should heed posted rules, check for advisories before entering the water, and be mindful that overnight lows and early/late season temperatures can make swimming uncomfortable or unsafe.
