open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
901 am cdt wed sep 17 2025

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 around 30.3 inches in eastern quebec will continue
east today as low pressure around 29.7 inches slowly lifts
northeast into the hudson bay. warm temperatures and light winds
will persist through today and bring a potential for fog tonight.

winds are then expected to increase a bit and shift more easterly
thursday and beyond as another area of low pressure around 29.9 
inches develops across the central plains. as the low lifts into 
the great lakes region this weekend, stronger winds up to around 
25 kt will be possible.
