open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
159 am cdt fri jul 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...

large high pressure around 30.1 inches will remain parked over 
the ohio valley and appalachian mountains into friday night. 
meanwhile, a trough of low pressure will remain over the great 
plains through tonight. a weak low pressure area may then 
organize and slowly move across wisconsin and lake michigan from 
saturday afternoon into sunday, or pass farther south across 
illinois into the ohio valley. modest south to southwest winds 
will become a bit lighter today. light to modest winds are then 
forecast for the weekend, but with some uncertainty on wind 
direction given low confidence in the track of the low. a stormy 
period is expected for central and southern lake michigan from 
through the weekend. patchy marine fog will be possible at times 
as warm and humid air flows over the relatively cooler lake.
