open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
212 pm cdt fri oct 23 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...

30.4 inch high pressure is centered over quebec this afternoon, 
with 29.4 inch low pressure positioned over northeastern montana.
positioning of these surface features is resulting in generally 
south to southeasterly winds across the waters. areas of fog, some
of which have been dense, will linger through the first half of 
the afternoon. based on observational trends, have maintained the 
marine dense fog advisory across portions of the waters through 3 
pm cdt, and will be monitoring for additional adjustments. 
expecting fog to fully dissipate by early evening at the latest. 
aforementioned area of low pressure will progress toward lake 
winnipeg tonight, continuing on toward the hudson bay by saturday 
evening as it deepens to near 29.2 inches. progression of the low
will maintain generally southerly flow across the waters, with 
gusts between 25-30 knots possible over the northern half of the 
lake saturday afternoon and night. can't rule out an isolated gust
approaching gale force during this time frame, with conditions 
not expected to be widespread enough for headlines.

winds will trend southwesterly while steadily weakening ahead of an 
approaching cold front on sunday. currently expecting the front to 
move south across lake michigan late sunday afternoon into sunday 
evening, bringing a breezy northeast wind shift. gales are not 
anticipated during the frontal passage, with any isolated rain 
showers expected to remain over the far northern part of the lake. 
breezy northeast winds will continue through monday as 30.7 inch 
high pressure slides into ontario from the canadian great plains. 
winds will trend easterly and eventually southerly tuesday into 
the middle of next week as the aforementioned high shifts into the
northeastern united states. widespread rain chances return 
wednesday into friday.
