*** 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
Keith Sebelius Lake experiences typical Midwestern seasonal variations in surface water temperature. In spring (April–May) surface temperatures commonly range from about 50–65°F (10–18°C) as the lake warms after winter. Summer months (June–August) bring the warmest conditions, with surface readings often between roughly 70–82°F (21–28°C) on sunny, calm days; shallow coves can be a few degrees warmer. In autumn (September–October) the lake cools again to roughly 55–70°F (13–21°C). During winter the surface frequently sits near freezing, about 32–45°F (0–7°C), and parts of the reservoir can develop ice depending on air temperatures and snow cover.
Swimming at Keith Sebelius Lake is generally permitted, but it is subject to local conditions and signage and is typically undertaken at one’s own risk because developed supervised beaches are limited. Water temperature is the main seasonal determinant of comfort and safety: summer temperatures make recreational swimming feasible, whereas cold shoulder seasons and winter are unsafe due to hypothermia risk and possible ice. Other factors such as changing water levels, underwater structures, boat traffic and occasional water-quality advisories can restrict or discourage swimming, so visitors should observe posted warnings and use caution.
