open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
237 am cdt fri apr 10 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...

a stationary front will remain just south of lake michigan through
friday, leading to continued light to moderate north winds. high 
pressure will then build over the upper great lakes region 
friday night into saturday morning, causing winds to become 
light and variable. southeast winds return saturday afternoon 
and become gusty saturday night as a sharper pressure gradient 
moves over the lake as low pressure moves into the northern 
great plains.

low pressure will shift into the northern great plains during the
day sunday as it deepens to near 29.4 inches. the low will quickly
shift east toward lake superior sunday night, reaching the
southern shores of the hudson bay by daybreak monday morning.
winds will thus increase further across the open waters sunday
through sunday night. will be monitoring for gale potential
during this time frame, particularly over the northern half of
lake michigan. the need for headlines will continue to be
evaluated as this portion of the period approaches. winds will
weaken monday morning as 30.0 inch high pressure moves across
ontario.

passing low pressure systems will lead to persistently active
conditions across lake michigan saturday afternoon into next week,
with multiple chances for showers and thunderstorms forecast. will
need to monitor thunderstorm development during the monday-
wednesday time period, as some storms could become strong to
severe.
