open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
900 am cdt sun oct 11 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...

light to modest south winds continue through monday as broad low 
pressure lingers over the upper mississippi river valley. this 
low pressure, around 29.6 inches, will tighten up and track 
northeastward across central lake michigan late monday into early
tuesday, with chances for isolated thunderstorms. northwest winds
arrive behind the associated cold front into tuesday, veering 
northerly or even northeasterly into wednesday. 

a stronger low pressure system is possible later this week, which
could bring gusty east to southeast winds and shower / storm 
chances into thursday. the associated cold front and incoming 
strong high pressure may then yield gusty northwest winds friday 
into saturday, with gales possible.
