open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
903 am cst sat nov 15 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...

breezy southwest to west winds will become northwest this
afternoon, as low pressure around 29.3 inches drags a cold front
across the lake. the gusty northwest winds are expected to
continue into sunday. 

wind gusts around 30 knots are expected during this period, with 
a few gale force gusts possible in the northern third of the open 
waters, as well as along the eastern lakeshore areas. still do not
have high enough confidence for gusts exceeding gale force for 
extended period, thus will continue to hold off on gale headlines 
at this time. 

winds begin to ease sunday night through monday, as high pressure
around 30.1 inches builds into the upper midwest. another low 
pressure system around 29.9 inches is expected to track from the 
central plains to south of lake michigan through the middle of 
next week.
