OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
829 AM CST Sun Nov 16 2025

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...

Gusty northwesterly winds continue today as Lake Michigan remains
sandwiched between low pressure around 29.2 inches well to the
east over New England and an incoming high pressure around 30.0
inches from the northern Plains. Wind gusts around 30 kt are expected
through the afternoon. As high pressure slides eastward across
the Upper Midwest overnight into Monday, winds will ease and
gradually shift before the high moves over Lake Michigan Monday
night. Another area of low pressure around 29.8 inches pushes in
from the Plains across IL for Tuesday and will bring east-
southeasterly winds, with the strongest winds over the southern
half of the Lake. Lighter winds are then expected into midweek as
another high treks across the Upper Great Lakes region.
