Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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 Salmon River in Idaho, often called the River of No Return, is a remarkable waterway surrounded by dramatic wilderness and steep canyons. Its water temperatures are strongly influenced by the season and elevation. In the summer, the river typically warms to around 60–70°F (15–21°C), making it comfortable for swimming in calmer stretches. In the spring, however, snowmelt from the surrounding mountains keeps the water cold, often below 50°F (10°C), which can be invigorating but challenging for extended swimming.
Swimming opportunities are plentiful, especially during the warmer months when the river becomes a hub for outdoor recreation. Sandy beaches along the riverbanks provide inviting spots to relax and wade into the water, particularly in slower-moving sections near campsites and recreation areas. However, the Salmon River is also known for its powerful rapids and strong currents, so swimming should always be approached with caution. For those seeking adventure, its clear waters and remote setting offer a refreshing and unforgettable way to connect with nature, provided safety measures are taken seriously.
