*** 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 Klamath River, stretching through southern Oregon and northern California, is a striking and ecologically significant river known for its rugged beauty. Water temperatures in the Klamath River vary with the seasons and the section of the river. In colder months, temperatures often range from 35°F to 50°F (2°C to 10°C), while summer months see a rise to 60°F to 70°F (15°C to 21°C), particularly in calmer, sunlit stretches. This seasonal warmth makes certain areas more inviting for recreational activities during the summer.
Swimming in the Klamath River is possible in some sections, especially during the warmer months, but it is often secondary to other activities like fishing, rafting, and kayaking. The river is known for its strong currents in certain areas, so swimmers should exercise caution and stick to calmer sections or designated swimming spots. The natural beauty of the surrounding landscape and the diversity of wildlife make the Klamath a favorite destination for outdoor enthusiasts, offering opportunities to enjoy the water and immerse yourself in the region’s pristine environment.
