open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
837 pm cdt wed sep 16 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 near the ontario-quebec 
border late this evening, and will continue east through the day 
tomorrow. progression of the high will maintain east-northeast 
winds across the open waters through tomorrow afternoon. 
occasional periods of showers and thunderstorms will continue into
thursday, with severe weather not expected.

a new area of 30.4 inch high pressure will shift from the 
canadian great plains into ontario thursday night into friday 
morning, maintaining east-northeast winds across lake michigan. 
29.9 inch low pressure will develop near the missouri river 
friday afternoon, moving over or just south of waters during the 
day on saturday. winds will veer east-southeasterly ahead of the 
low, becoming gusty at points. some gusts could approach gale 
thresholds, particularly on friday night and saturday morning. 
whether borderline gales will be widespread enough to warrant gale
warnings remains uncertain at this time, with trends being 
monitored through the end of the week. areas of widespread showers
& storms will accompany the approaching/passing area of low 
pressure friday night through at least saturday night, with 
widespread severe weather not expected at this time. winds will 
trend northeasterly as the low slowly moves into the ohio river 
valley sunday into the beginning of next week.
