open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
243 am cdt thu apr 23 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 few areas of fog may develop over southern portions of the lake 
early this morning, lifting northward and likely eroding through the 
course of today. south to southeast winds accelerate across the lake 
this morning and afternoon as low pressure around 29.2 inches tracks 
eastward across the northern great plains. due to a surface high 
pressure ridge over far southeastern ontario canada, winds remain 
due easterly over the northern tip of the lake today into friday, 
and may gust to around 30 kt tonight into friday. 

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, predominantly due north saturday and northeast sunday. 
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 its 
arrival and gusty west winds behind it (into tuesday). not seeing 
widespread gale potential with this system, though trends will be 
monitored.
