open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
908 pm cdt mon mar 9 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 backdoor cold front will continue southward across lake michigan
through the overnight hours, bringing breezy northeasterly winds
behind it. pockets of marine dense fog may develop over southern
portions of the lake overnight into tuesday morning (mainly ahead
of the front). northeast winds behind the front should gradually 
clear out the fog (if applicable) by mid day tuesday. 

low pressure around 29.6 inches develops in the central great 
plains and progresses into northern illinois tuesday night. there 
is some potential for thunderstorms across the southern third of 
the lake north of the associated warm front late tuesday 
afternoon through tuesday evening, with a continued northeast 
breeze. low pressure ejects to the lower great lakes into 
wednesday morning, turning winds northwesterly and allowing rain
to slowly transition to snow. north to northwest gales are 
possible wednesday morning through wednesday afternoon, mainly 
over the south half of the lake. winds gradually diminish into 
thursday morning.

another round of gales is possible thursday night into friday as a
compact clipper low of 29.2 inches crosses northern lake michigan.
