open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
919 am cdt mon apr 13 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 broad area of low pressure around 29.4 inches will become 
deeper over southern hudson bay this morning. this will bring 
continued breezy south winds to all of lake michigan. winds will 
weaken later this morning as the aforementioned area of low 
pressure quickly moves away and the trailing cold front stalls 
over central lake michigan. then, a couple passing low pressure 
system along the stalled front will lead to intermittent showers 
and thunderstorms through the middle of the week. areas of dense 
fog will likely occur at times due to a relatively mild and humid 
airmass over the cold waters. will be monitoring observational 
trends and issuing dense fog advisories should conditions warrant.
