OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
851 AM CST Mon Jan 26 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...

Elevated waves and cold temperatures will support moderate to
heavy freezing spray through Tuesday afternoon. A Heavy Freezing
Spray Warning is in effect until 6 PM CST Tuesday.

Breezy northwest winds with gusts of 25 to 30 knots over the open
waters will persist into the afternoon hours. These breezy winds
will be caused by the tight pressure gradient between a 30.7 inch
high moving south through the Central Plains and a 29.5 inch low
moving east across the Mid Atlantic states.

Tonight a 30.5 inch high pressure will build into the Ohio River
Valley as 29.6 inch low pressure trough crosses Lake Superior
resulting in a west- southwest wind shift across Lake Michigan.
Winds will become gusty at times tonight into Tuesday morning,
and a few hours of southwest gales are possible during the late
evening.

Winds will trend west-northwesterly Tuesday afternoon and night as
30.4 inch high pressure builds into the northern Great Plains.
Winds will gradually taper Wednesday through Thursday as said area
of high pressure moves into the upper Mississippi River Valley.
