open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
333 pm cdt thu jul 2 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 today into friday night. 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 persist today becoming a bit lighter tonight and friday.
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 tonight into the weekend. patchy 
marine fog will be possible at times as warm and humid air flows 
over the relatively cooler lake.
