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...

modest west to northwest winds will prevail overnight, as strong 
low pressure remains over quebec, and a weak cold front moves 
across lake michigan. the strong low over quebec will then move 
over eastern hudson bay for wednesday into thursday, which will 
aid in moving a stronger cold front across lake michigan. thus, 
brisk northwest winds and moderate freezing spray is expected for 
wednesday through thursday morning. a few gale force wind gusts 
will be possible over far northern lake michigan wednesday into 
wednesday evening. modest to brisk west to northwest winds will 
then continue the remainder of the week.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
837 pm cst tue dec 30 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...

modest west to northwest winds will prevail overnight, as strong 
low pressure remains over quebec, and a weak cold front moves 
across lake michigan. the strong low over quebec will then move 
over eastern hudson bay for wednesday into thursday, which will 
aid in moving a stronger cold front across lake michigan. thus, 
brisk northwest winds and moderate freezing spray is expected for 
wednesday through thursday morning. a few gale force wind gusts 
will be possible over far northern lake michigan wednesday into 
wednesday evening. modest to brisk west to northwest winds will 
then continue the remainder of the week.
