open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
905 pm cdt sat aug 29 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...

high pressure around 30.2 inches will continue to move east of 
the lower great lakes tonight, while low pressure deepens to 
around 29.6 inches in the central great plains. this will support
modest to breezy southerly winds. tonight a warm front is 
expected to lift northward over the lake, and the presence of a 
jet aloft may cause some gusty southerly winds to 30 knots over 
the south half of the lake on sunday. 

breezy southerlies then remain into monday as the low will lift
northeast from the plains toward western lake superior. scattered
thunderstorms will occur at times from tonight into next week. a 
weak cold front will finally arrive late tuesday night and 
wednesday with light northerly winds eventually taking hold.
