open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
318 am cdt tue mar 10 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 cold front will continue southward across southern lake 
michigan this morning, reaching the southern shore after
sunrise. the northeast winds will remain rather light over the far
southern portion of the lake, where areas of dense fog may form
today and continue tonight. farther north toward central lake 
michigan, brisk northeast winds and building waves are expected. 

low pressure around 29.6 inches develops in the central great 
plains and progresses into northern illinois tonight. there is 
some potential for thunderstorms across the southern third of the 
lake late this afternoon and tonight. low pressure ejects to the 
lower great lakes into wednesday morning, turning winds 
northwesterly and allowing rain to slowly transition to snow. 
infrequent gale force gusts will be 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.
