open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
252 pm cdt mon aug 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...

the stationary front remains over the far southern portion of the
lake with light and variable winds due to high pressure around 
30.0 inches sitting north of a frontal boundary that is parked 
over the corn belt. otherwise an unsettled weather pattern has set
up over the upper great lakes for the start of this week where 
weak waves of low pressure will cross the region and produce 
rounds of thunderstorms at times, primarily over the southern half
of lake michigan. a few strong storms are expected over the
southern 2/3 of the lake tonight and again tuesday late morning 
to early afternoon.
