Open Lake Forecast for Lake Superior
National Weather Service Marquette MI
1000 PM EST Sat Jan 24 2026

For waters beyond 5 nautical miles of shore on Lake Superior.

Waves are the significant wave height - the average of the
highest 1/3 of the wave spectrum. Occasional wave height is the
average of the highest 1/10 of the wave spectrum.

.SYNOPSIS...

30.6 inch ridging over Lake Superior this gradually weakens to 30.3
inches into tomorrow, then further to around 30.1 inches into
Monday, as a 29.6 inch low moves northeast along the Atlantic Coast.
A 29.8 inch clipper low crosses the lake Monday night into Tuesday.
Another clipper low, much weaker at 30.1 inches, grazes the
northeast portion of the lake on Wednesday. A strong high pressure
descending from the Canadian Prairie around 30.7 inches late next
week brings ridging back to Lake Superior, likely persisting into
next weekend.
