open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
855 pm cdt sat oct 24 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...

low pressure near 29.2 inches will progress toward the hudson bay
this evening. 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 this afternoon and 
tonight. can't rule out an isolated gust approaching gale force 
during this time frame, with conditions not 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 sunday evening and night, 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 south to southwesterly tuesday into thursday as the
aforementioned high shifts into the northeastern united states. 
widespread rain chances return wednesday into friday.
