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
Dale Walborn Reservoir, like many small inland reservoirs in Ohio, experiences marked seasonal swings in surface water temperature. In winter the lake commonly approaches near-freezing conditions, roughly 32–45°F (0–7°C). Spring sees a steady rise as sunlight and runoff warm the shallower margins to about 45–65°F (7–18°C). Peak summer temperatures often reach the most comfortable range for recreational water contact, typically about 65–80°F (18–27°C), and in warm, shallow bays can climb toward the mid-80s°F (around 29°C) on heat waves. Autumn brings a cooling trend back down toward 50–65°F (10–18°C). Local factors — depth, shading, inflow and outflow, and recent weather — cause variation from year to year and between different parts of the reservoir.
Whether swimming is allowed at Dale Walborn Reservoir depends on the rules set by the agency that manages the site. Many smaller Ohio reservoirs restrict or discourage swimming for reasons including water-quality protection, the absence of lifeguards, underwater hazards and use of the impoundment for water supply or wildlife management. Where swimming is permitted, it is safest during the warm summer months when surface temperatures are in the mid-60s to 80s°F (18–27°C); cooler temperatures in shoulder seasons carry a higher risk of cold-water shock and hypothermia. Visitors should confirm current access rules and safety advisories with local authorities before entering the water.
