*** 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 Malheur River, flowing through eastern Oregon, is a relatively small but significant river known for its arid surroundings and remote beauty. The river's water temperature can vary significantly throughout the year, with colder temperatures in the spring and early summer due to snowmelt from the nearby mountains. During the warmer summer months, the water temperature can rise to more comfortable levels, typically ranging from 60°F to 75°F (15°C to 24°C), particularly in calmer stretches.
Swimming in the Malheur River is possible but not common. The river’s relatively low flow and the warm summer temperatures make it more suitable for a quick dip or wading in some of its calmer sections. However, the river is more frequently enjoyed for fishing and wildlife viewing, as its ecosystem supports a variety of local species. While the water may not be warm enough for prolonged swimming in many parts, visitors can still enjoy the river's peaceful atmosphere and stunning surroundings, making it a great spot for those seeking a tranquil outdoor experience.
