open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
256 pm cdt sun mar 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...

breezy southwest winds continue through this afternoon as a cold 
front begins to approach the waters from the north. the front will 
gradually advance south across lake michigan tonight through 
tuesday. this will result in generally east-northeast winds across 
the northern half of the lake with southerly winds further south. a 
few gales are possible over southeastern lake michigan monday night, 
but aren't expected to be widespread. periods of showers and 
thunderstorms will accompany the slow-moving front, with a few 
stronger storms possible monday night and once again on tuesday. 
large hail would be the primary threat in any stronger storms.

winds will trend northerly behind the departing cold front tuesday 
evening through wednesday. will be monitoring trends for a few gusts 
approaching gale force tuesday night into wednesday, with the 
current expectation being for any such gusts to be isolated. 30.7
inch high pressure will shift from ontario to quebec through the 
late week time period as 29.8 inch low pressure builds into the 
ohio river valley, allowing winds to trend east-northeasterly. 
will need to watch for additional isolated gale potential thursday
into friday as low pressure passes near or over lake michigan, 
with the continued expectation for any gusts to be too sparse to 
justify headlines. will nevertheless be monitoring trends into 
this week. additional rain and snow will accompany the 
approaching/passing area of low pressure thursday into next 
weekend.
