open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
240 am cdt mon mar 30 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...

modest southwest winds continue as a front begins to approach the
waters from the north. the front will gradually advance south 
across lake michigan through tuesday. this will result in 
generally east-northeast winds across the northern half of the 
lake with southerly winds further south. periods of showers and 
thunderstorms will accompany the slow-moving front, with a few 
stronger storms possible tonight 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 29.7 inch low pressure approaches from
the southwest, 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.
