Every Chicago Lakefront Beach, Ranked by Advisory-Level Water Tests

North Avenue Beach has the cleanest water-test record on Chicago's lakefront - 1.4 percent of its lab tests since 2021 at or above the swim-advisory action level - while 63rd Street sits at 10.3 percent, seven times that share. All 17 lakefront beaches ranked from the city's own 9,524 lab results, with Humboldt's inland lagoon counted apart.
