Waves near Chicago, Illinois

Thursday, October 29, 2026 · NOAA buoy 45198, Chicago Buoy (9 km from the city centre)

Chicago Buoy has not reported waves in the last 6 hours. Buoys go offline for maintenance, and Great Lakes buoys are taken out of the water for winter.

Measured, not forecast: live readings from the US National Data Buoy Center (operator: Illinois-Indiana Sea Grant and Purdue Civil Engineering), refreshed about every 30 minutes. Significant height is the average of the highest third of waves; single waves can be nearly twice as high. Conditions at the beach can differ from the buoy.
