open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
902 pm cdt wed oct 14 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...

winds will gradually become easterly tonight into thursday as 
high pressure around 30.3 inches slides through the region. the 
stronger winds are expected across the southern half of the lake 
during this time. then two areas of low pressure are progged to 
merge over the great lakes region into a single low pressure for 
thursday and deepen to around 29.5 inches as it shifts into the 
eastern great lakes later thursday through friday. expect a 
northwesterly wind shift to ramp up and increase to gales and 
nearing storm force at times on the backside of the departing low 
pressure while a strong high pressure around 30.7 inches builds to
the west. thus will maintain a gale watch for all the open waters
of lake michigan friday morning into friday night.

as the high sinks toward the ohio river valley on saturday, strong low
pressure around 29.1 inches will develop in northern manitoba. the
tight pressure gradient may bring southwest gales to lake 
michigan on sunday.
