*** 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 Payette River in Idaho is a strikingly beautiful waterway, known for its rugged canyons and pristine mountain scenery. The river’s water temperature can vary widely depending on the season and elevation, with cooler temperatures prevailing due to snowmelt feeding much of its flow. In summer, water temperatures can rise to the mid-60s°F (around 18°C), particularly in the lower sections, providing a refreshing but brisk environment for aquatic activities.
While the Payette River is highly regarded for whitewater rafting and kayaking due to its challenging rapids, opportunities for swimming are more limited and best suited to calmer sections or side pools along the river. The beaches and eddies in certain areas can be enjoyable for a quick dip on hot summer days, but swimmers should be cautious of the river’s cold temperatures, swift currents, and rocky terrain. As always, wearing a life jacket and choosing safe spots away from rapids is recommended for a relaxing and secure experience.
