open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
855 am cdt thu mar 12 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...

high pressure of 30.2 inches approaching from the west will move
across lake michigan midday. thus decreasing northwest winds are
expected this morning then backing southerly into the afternoon as
the high moves away.
 
strong low pressure of 29.0 inches is then expected to move 
through northern wisconsin into northern michigan tonight into 
friday. increasing southerly winds are expected late this
afternoon and evening ahead of the low. southerly gales are
expected over the entire lake by late evening then becoming west
northwesterly for friday. a gale warning is now in effect from
late this evening into friday evening. confidence is increasing in
storm force gusts over the southern half of the open waters, with
storm warning upgrades being considered in the upcoming forecast. 

winds are expected to ease friday night into saturday as high 
pressure of 30.3 inches moves in from the northwest. another 
strong low pressure system is likely to move through the region 
late in the weekend into early next week, with another round of 
gales likely. a colder air mass behind the low may lead to a 
round of heavy freezing spray sunday night into monday as the 
strong winds and higher waves linger.
