open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
905 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 sit over the  
appalachian mountains and a trough of low pressure will remain 
over the great plains through tonight. a weak low pressure area 
will then organize and slowly move across wisconsin and lake 
michigan from saturday afternoon into sunday. scattered showers 
and thunderstorms are expected at times through the weekend. 
patchy marine fog will be possible as warm and humid air flows 
over the relatively cooler lake.
