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 today and tonight 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. wind gusts should remain 
just below gale force. 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
908 am 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 today and tonight 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. wind gusts should remain 
just below gale force. modest to brisk west to northwest winds
will then continue the remainder of the week.
