open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
851 am cst thu jan 15 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...

winds will continue to decrease across the open waters through
today as 30.1 inch high pressure moves across lake michigan. low 
pressure of 29.4 inches will move into lake superior late tonight
into friday morning, resulting in increasing southwesterly winds 
across the waters throughout tonight. winds will back
northwesterly through the day saturday, with gusts around 30 kt 
expected.

an additional low pressure system will progress southwest through
the canadian prairies into the upper great lakes sunday, bringing
increasing southwesterly winds through the day. a cold front will
shift winds northwesterly sunday night, with increasing potential
for gales. gales may continue through monday afternoon, particularly
across the southern half of lake michigan. northwesterly winds
will slowly ease through monday night.

moderate freezing spray will remain a concern through sunday.
following the frontal passage sunday into monday, gusty winds
and even colder air will result in the potential for widespread
heavy freezing spray.
