open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
853 pm cdt thu mar 19 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...

south to southwest winds are expected to develop overnight, as 
low pressure around 29.7 inches progresses southeast into northern
lower michigan. winds will shift to northwest to north friday 
morning, as a cold front shifts southeast across the lake. winds
become light friday night, as high pressure around 30.3 inches 
builds into ontario. 

low pressure around 29.5 inches develops in the lee of the 
wyoming rockies saturday morning, shifting winds south. the low 
should move southeastward saturday night, allowing winds to 
increase and shift to the north and northeast across the northern
half of the lake. 

the low should move across central illinois into indiana sunday, 
as it deepens to around 29.4 inches. this should lead to northerly
winds backing to northwesterly sunday into sunday night across the
lake. a few gales are possible during this timeframe. high 
pressure around 30.5 inches should then bring decreasing winds 
for monday.
