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
Lake Benton, a shallow prairie lake in southwestern Minnesota, experiences a clear seasonal pattern in water temperature. In winter the surface typically approaches freezing and often freezes over, hovering around 32°F (0°C) or slightly lower under ice. Spring warming brings surface temperatures into the 40s and 50s°F (roughly 4–15°C) as ice melts and the lake stratifies. During summer the upper water commonly reaches the 70s°F, often between about 68–80°F (20–27°C) on warm days, while deeper or cloudy periods can keep parts of the lake cooler. In autumn the surface cools back into the 50s and 60s°F (10–20°C) as the lake releases summer heat and moves toward turnover.
Swimming in Lake Benton is generally permitted and used recreationally during the warmer months because there are public access points and shorelines managed for recreation. Practical considerations determine when it’s appropriate: water that is in the 70s°F (around 21–27°C) is comfortable for most swimmers, whereas spring and late-season temperatures can feel cold and increase hypothermia risk. Ice cover and formal advisories for water quality or blue‑green algae can temporarily restrict swimming, so visitors should follow posted guidance and local safety recommendations before entering the water.
