OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
154 PM CST Sun Nov 1 2026

FOR WATERS BEYOND FIVE NAUTICAL MILES OF SHORE ON Lake Michigan.

Waves are provided as a range of significant wave heights, which
is the average of the highest 1/3 of the wave, along with the
average height of the highest 10% of the waves which will
occasionally be encountered.

.SYNOPSIS...

High pressure near 30.5 inches will drift southeast into the
northeastern United States through this evening, maintaining
south- southeasterly winds over Lake Michigan. Low pressure near
29.5 inches will develop over eastern Colorado this evening,
progressing into the Upper Mississippi River Valley by early
Tuesday morning. Winds will steadily become gusty ahead of the
low, approaching or exceeding gale force over at least the central
third of the lake Tuesday afternoon and evening. Anticipate that
headlines will become necessary in later forecasts. Rain will
accompany the approaching/passing low Monday through Tuesday
night, with a few thunderstorms possibly mixing in. Severe weather
is not expected at this time.

Winds will remain breezy, though likely below gale levels Wednesday
and Wednesday night as 30.1 inch high pressure slowly builds into
the Canadian Great Plains. Said high will move into the western
Great Lakes through the second half of next week, allowing for
westerly and eventually northerly winds by next weekend.
