Wave and water readings come from NOAA buoy data when the station reports them. Missing values mean the buoy did not report that field — we never invent lake numbers.

What wind means for recreational boating

Downtown air temperature is not the same as Lake Michigan. Wind over open water builds chop faster than the same breeze feels on land, and thunderstorms can arrive with little room to run for a harbor.

As a conservative rule of thumb for small recreational boats: winds climbing through the teens often mean a tougher ride; mid-20s and higher — especially with gusts or a small craft advisory — are a strong reason to stay docked unless you and your vessel are truly prepared.

This site's Good / Caution / Poor summary is informational only. Official NOAA/NWS marine forecasts and a qualified captain's judgment always come first.

Seasonal tip

Lake Michigan water stays colder than downtown air for much of the season — dress for the water temperature, not the skyline temperature.
