open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
250 pm cdt thu oct 8 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 30.1 inches will cross wisconsin tonight. 
winds will become southerly on friday as the high departs and 
low pressure around 29.2 inches develops in the northern plains.
the tight pressure gradient over lake michigan will produce 
breezy southerly winds up to 30 knots from friday night through 
sunday morning. a few gale force gusts may occur in the northern
half of the lake saturday afternoon and evening. 

lighter winds are expected monday as a weak low pressure trough 
around 29.7 inches slowly moves from minnesota to wisconsin. look 
for gusty northwest winds to develop monday night into 
tuesday after the passage of a cold front as high pressure of 
30.1 inches builds into the upper midwest.
