open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
301 am cdt wed apr 22 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 weak surface boundary will continue to work it's way southward
across the southern quarter of lake michigan early this morning, 
with light and variable winds over southern portions of the lake 
and a northeast breeze over the rest. the stagnant air ahead of 
this boundary over southern lake mi (mainly along and south of a 
milwaukee wi to whitehall mi line) may cool to saturation this 
morning, with areas of fog possible. light winds, predominantly
out of the northeast, then continue through the rest of today.

winds veer southeast and accelerate tonight through friday 
morning as 29.2 inch low pressure develops over the northern great
plains and slowly tracks eastward. though winds will be breezy
(particularly thursday afternoon and onwards), gales are not
anticipated at this time. some ~30 kt easterly winds may occur
over the northern tip of the lake due to a surface ridge of high 
pressure in southeastern ontario canada sharpening the pressure 
gradient. 

the low will pull a cold front across lake michigan friday 
afternoon and evening, resulting in a breezy north-northwest wind
shift. showers and thunderstorms are expected late thursday night
through friday, both ahead of and along the front. severe weather
is not anticipated at this time.

northerly winds will continue through the weekend across lake 
michigan. 29.4 inch low pressure is forecast to track 
northeastward from the central great plains (sunday night) near or
over lake michigan (monday night), with gusty east to southeast 
winds ahead of it's arrival and gusty west or northwest winds 
behind it (into tuesday). not seeing widespread gale potential 
with this system, though trends will be monitored.
