open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
253 pm cdt sun apr 12 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...

low pressure around 29.4 inches will track across the northern 
great plains to northeast minnesota into this evening, then 
develop toward the hudson bay into early monday morning. this 
will bring breezy south winds to all of lake michigan, but with 
the gales over the north third this evening into early monday 
morning. thus have upgraded to a gale warning.

winds will weaken later monday morning as the low quickly moves 
away and the trailing cold front stalls over northern lake 
michigan. then, another passing low pressure systems along the 
stalled front will lead to intermittent showers and thunderstorms 
through the middle of the week. areas of dense fog will likely 
occur at times due to a relatively mild and humid airmass over the
cold waters.
