open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
829 pm cdt wed apr 29 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...

widespread gales are not expected through the duration of the period 
across the open waters of lake michigan. currently north-northwest 
winds will continue through the end of the week as 29.6 inch low 
pressure shifts into the canadian maritime provinces & 30.2 inch high
pressure builds into the northern great plains. winds will trend 
south-southwesterly saturday into sunday as the aforementioned 
area of high pressure moves into the ohio river valley and 29.5
inch low pressure forms over the hudson bay. winds will briefly 
veer westerly sunday night into monday as a weak cold front 
crosses lake michigan. showers and a few thunderstorms will 
accompany the front, with severe weather not anticipated at this 
time.

a second area of stronger low pressure near 29.3 inches will 
develop over the lake superior vicinity during the day monday, 
ultimately shifting toward the southern hudson bay and quebec on 
tuesday. progression of the low will allow winds to trend west- 
southwesterly monday night through wednesday. a cold front is 
forecast to cross the open waters wednesday afternoon, bringing a 
northwest wind shift. additional periods of showers and embedded 
storms are forecast sunday night into the middle of next week,
