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.

Location & Local Information
The Tri-Cities area in Washington, comprising Richland, Kennewick, and Pasco, is located at the confluence of the Columbia and Snake Rivers. The Snake River, which flows through the region, offers various recreational activities, although its water temperature can vary significantly. During the summer months, the water temperature in the Snake River near the Tri-Cities typically ranges from 60°F to 70°F (16°C to 21°C), making it somewhat cool but still refreshing for activities such as boating, fishing, and kayaking. However, the water is generally too cold for comfortable swimming, especially early in the season when snowmelt contributes to lower temperatures.
Although swimming directly in the Snake River is less common due to its cooler temperatures and occasional strong currents, the river remains a popular spot for water sports. Many people enjoy floating down the river in inner tubes or engaging in fishing and watercraft activities. For those seeking a warmer swimming experience, there are alternative options within the Tri-Cities area, including public pools that maintain water temperatures around 78°F to 82°F (25°C to 28°C). These pools are ideal for a comfortable swim during the summer heat.
Additionally, nearby lakes such as Badger Lake and the Columbia River offer more favorable conditions for swimming, with water temperatures often reaching between 70°F and 80°F (21°C to 27°C) during the summer. These lakes and reservoirs are more conducive to swimming, making them popular spots for residents of the Tri-Cities who want to enjoy a traditional swim in warmer waters.
