*** 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.

The South Platte River, flowing through Colorado, Nebraska, and Wyoming, offers a mix of cool mountain-fed waters and warmer stretches as it moves into the plains. The water temperature is typically cooler in the upper reaches, especially in the mountainous areas, where snowmelt contributes to the river’s flow. During the summer months, the water temperature generally ranges from 50 to 70°F (10 to 21°C), providing a refreshing environment for swimming, especially in the slower-moving sections. In the winter, the temperature can drop significantly, often falling below 40°F (4°C), making swimming less appealing.
While the South Platte River is not widely known for swimming, it does offer opportunities for water-based recreation in certain areas. Calm stretches and designated parks along the river can be suitable for wading, tubing, or a quick dip in warmer months. However, the river's current can be strong in some areas, and water quality may vary, so swimmers need to be cautious, especially after rainfall or in agricultural regions. The South Platte is more often enjoyed for activities like fishing, kayaking, and rafting, with its scenic beauty and access to outdoor adventures making it a popular spot for nature lovers.
