open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
237 am cst tue feb 3 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...

a light north to northwesterly breeze continues this morning as 
high pressure of 30.5 inches builds over northern minnesota. 
expecting high pressure to weaken slightly as it moves overhead 
tonight into wednesday, bringing light winds to the lake. high 
pressure will slide south wednesday night into thursday, as low 
pressure around 29.3 inches progresses eastward into hudson bay. 
expect winds to shift southwesterly into thursday morning, 
increasing and becoming gusty thursday afternoon through thursday 
night ahead of a cold front. cold front will shift winds back to 
northwesterly, and will likely bring a period of gales friday into
friday night. winds diminish into saturday morning as high 
pressure builds back into the region, but a clipper system 
developing saturday night into sunday will allow winds to increase
and shift back to westerly.
