The answer is a resounding yes—Lake Chelan is not only swimmable, but it’s also one of the most scenic and refreshing freshwater swimming destinations in Washington State.

Yes, You Can Swim in Lake Chelan

Lake Chelan is open to swimming year-round, though the most popular months are June through September, when surface water temperatures are at their warmest. Whether you're visiting with family, planning a solo adventure, or just looking to cool off after a hike, swimming is a favored activity here.

How Cold Is the Water? Know Before You Go

Lake Chelan is a glacially carved lake—deep, clear, and cold. Even on a hot July day, the water can feel surprisingly brisk. Here's what you can expect:

Summer Surface Temps: Around 65–70°F (18–21°C) near the southern end by Chelan and Manson.

Spring & Fall: Water remains cooler at 50–60°F (10–15°C).

Deeper Waters: Drop quickly to below 45°F (7°C) just a few feet down. The lake is nearly 1,500 feet deep!

If you're sensitive to cold, consider wearing a wetsuit, especially if you’re swimming away from shore or doing water sports.
