open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
158 pm cst sat jan 3 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...

west winds will become variable tonight and early sunday as a
broad area of high pressure averaging 30.1 inches moves across the
western great lakes. southerly winds will develop by sunday 
afternoon as that high becomes centered over central ohio, and low
pressure of 29.6 inches moves across southern minnesota. gales are
not expected, but winds over the open waters could aproach 30
knots before weakening monday morning. 

a few other system may impact the lake michigan area through mid
to late week with winds varying between westerly and southerly, 
but the probability of gales is low at this time.
