*** 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
Denver, Colorado, is located along the South Platte River, which provides a beautiful setting for a variety of outdoor activities. However, the water temperature in the river is typically too cold for swimming, especially when compared to more tropical destinations. During the summer months, the water temperature in the South Platte River generally ranges between 50°F (10°C) and 65°F (18°C), depending on the weather and snowmelt. Even at its warmest, the water remains relatively chilly, making it more suitable for activities like fishing, kayaking, and rafting rather than leisurely swimming.
As the river flows through urban and rural areas, the South Platte River can experience fluctuations in temperature due to factors such as seasonal changes and the release of water from reservoirs. During the spring and early summer, when snowmelt is at its peak, the water can be even colder, often dipping below 50°F (10°C). These colder temperatures, combined with the river’s swift currents, pose a safety risk for swimmers, and the strong flow of water makes it less inviting for casual swimming.
For a more enjoyable swimming experience, many residents and visitors to Denver choose public pools or nearby lakes. Denver's public pools typically maintain water temperatures between 78°F (26°C) and 82°F (28°C), providing a more comfortable environment for swimming, especially during the summer months. Additionally, nearby lakes like Cherry Creek Reservoir or Chatfield Reservoir offer warmer water temperatures, often ranging from 65°F (18°C) to 75°F (24°C) in the summer, making them better alternatives for swimming, boating, and other water activities.
