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 Yakima River, flowing through central Washington, is a popular spot for various outdoor activities, including swimming. During the summer months, the water temperature typically ranges from 60°F to 70°F (15°C to 21°C), which is cool but still comfortable for swimming, especially when temperatures rise in the surrounding areas. The river’s source in the mountains keeps it cooler in its upper reaches, while sections further downstream can warm up slightly, making them more inviting for a swim during the warmer weather.
Swimming in the Yakima River is most enjoyable in its calmer sections, where the water flow is more gentle. The river features a mix of fast-moving stretches and slower, deeper areas, and the latter is generally safer for swimming. Many people take advantage of the calm waters near popular parks or recreational areas for a refreshing dip or to float on tubes. However, swimmers should exercise caution in areas where the current is stronger, particularly after rainfall or in stretches with rapids.
The Yakima River runs through a stunning landscape of vineyards, orchards, and arid hills, providing a scenic backdrop for water activities. While it is more commonly known for activities like fishing, kayaking, and rafting, the river also offers great opportunities for swimming. Its combination of moderate water temperatures, picturesque surroundings, and various recreation spots make it an attractive destination for those looking to enjoy a swim or relax by the riverbank.
