We hope you enjoy a safe and relaxing Memorial Day weekend! The lakes look to be pretty cold still, and passing storms may lead to some moderate risk wind/wave activity. Check before you go!

The Green Bay buoy is in the water!
In central Green Bay, 20 miles west of Sturgeon Bay, GB17 will record real-time weather, wave, and water quality data, + webcam photos. Once an onboard power issue is sorted out, live data and images will be available: https://t.co/J3UoeiDX2F

@mtu_glrc has three full size buoys on Lake Superior in 2026, providing a wide array of parameters, including some novel water chemistry and quality measurements, and giving a better understanding of what happens out on the biggest of the big lakes.
