Boating conditions can change quickly. This rating is informational only and is not a substitute for official NOAA/NWS marine forecasts, local regulations, or the judgment of a qualified captain.
How to read waves, advisories, and nearshore forecasts
- Waves and wind on this page are area NOAA/NWS products for the selected forecast point — not a sensor at your exact ramp, harbor mouth, or breakwater.
- Marine alerts (for example Small Craft Advisories) apply to the NWS marine zones covering this area. Read the full alert text and end time on weather.gov before you cast off.
- Nearshore marine forecast excerpts are coastal waters guidance. Conditions inside protected basins can differ from open nearshore bands; always compare the latest full product.
- The Good / Caution / Poor card is an informational summary only — not a go/no-go clearance for any vessel or trip.

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.
