open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
310 am cst thu jan 22 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...

low pressure around 29.6 inches will move into quebec today, with
gusty west winds lingering over lake michigan. gale force gusts 
are expected over the southern two thirds of lake michigan into 
the middle morning hours, where a gale warning is in effect. a 
period of west to northwest gales are expected tonight into middle
morning on friday over the southern two thirds of the lake, and a
gale warning is in effect for this period as well.

gusty northwest winds will gradually diminish friday afternoon 
and night, as strong high pressure around 31.0 inches over the 
northern plains expands into the upper midwest. 

the gusty winds, arctic air and elevated wave heights will 
support periods of heavy freezing spray into friday night. a heavy
freezing spray warning is in effect for this period across all of
lake michigan.

the high will expand across the great lakes over the weekend, 
while weakening to around 30.5 inches. this should help winds
gradually weaken over lake michigan.
