open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
823 pm cdt tue jul 21 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...

gusty north winds continue late this evening across the open waters 
behind a departing cold front. gusts are expected to remain at or 
below 30 kts across the majority of the lake, though a few gusts 
approaching gale force remain possible through the predawn hours 
over the northeast half of the waters. winds will steadily subside 
through the day wednesday as 30.1 inch high pressure builds into 
the northern mississippi river valley from the great plains. the 
high will cross southern lake michigan thursday morning, 
progressing into the northeastern united states thursday night 
into friday. progression of the high will result in a south to 
southwest wind shift across the waters.

29.5 inch low pressure will move quickly from the canadian great 
plains toward quebec friday through saturday, maintaining south to
southwest winds over lake michigan. the low will attempt to pull 
a cold front into the western great lakes by sunday, with the 
boundary slowly advancing south across the waters through monday. 
the approaching/passing front will result in returning 
thunderstorm chances saturday night through monday, in addition to
a northerly wind shift by monday afternoon.
