open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
314 am cdt mon jun 23 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... 

a stationary front over the upper peninsula of michigan will lift 
north as a warm front over lake superior through dawn this morning.
low pressure around 29.6 inches will track just north of lake
superior through the post-dawn hours this morning. breezy south 
to southwest winds will continue into today ahead of an 
approaching cold front attached to the aforementioned low.

this cold front is still expected to move over the lake tonight 
into tuesday morning, easing the winds and stalling over the 
southern end of the lake tuesday morning through at least 
thursday. as a result, winds will be modest, with generally north 
winds through the work week until south winds return on thursday
as the front briefly lifts north ahead of approaching low pressure.
with the presence of the front, multiple round of thunderstorms 
are expected throughout the upcoming week.
