Water Temperature in Boise: General Trends and Swimming Opportunities
The Boise River, flowing through the city of Boise, Idaho, offers a variety of recreational activities, although swimming is generally not the most popular choice due to the river's varying conditions. During the warmer months, typically in late spring and summer, the water temperature in the Boise River can range from 60°F to 70°F (15°C to 21°C). While this temperature may feel refreshing on a hot day, the river's swift currents and the potential presence of rocks and debris make it less ideal for casual swimming.
That being said, the Boise River is a popular destination for activities such as tubing, kayaking, and paddleboarding. These activities are especially enjoyed during the summer, when the water temperature is more tolerable, and the river's flow provides a fun, natural current for tubing. For those looking to cool off, the river provides a refreshing spot, but it's best to enjoy it through these other recreational options rather than swimming.
For a more traditional swimming experience, Boise offers a number of community pools and nearby lakes where the water is calmer and more suitable for swimming. The proximity of the city to outdoor destinations also provides opportunities to visit nearby reservoirs and lakes, where water temperatures may rise to more comfortable levels for swimmers, typically around 70°F to 75°F (21°C to 24°C) in the summer months. These locations offer a safer and more enjoyable alternative for swimming enthusiasts.
