open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
859 pm 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...

a frontal zone should sag south to around a milwaukee wisconsin 
to whitehall michigan line into the overnight hours, with both 
wind flows becoming stronger over the far north and far south
portions of the lake. some 20 to 30 knot gusts may occur over the
northern third and southern third of the lake. showers and 
thunderstorms may occur into tuesday across the lake, with a few 
stronger storms possible at times (particularly near the frontal 
boundary). large hail would be the primary hazard with any 
stronger storms. 

the boundary will sag further south as a cold front tuesday 
afternoon, focusing lingering shower and thunderstorm activity 
over southern lake michigan, before washing it away later 
tuesday. gusty north winds will build in behind the front tuesday
evening into wednesday, with gusts up to 30 knots. winds should
then veer northeast through wednesday. 

high pressure around 30.7 inches will shift from ontario to 
quebec through the late week time period, as low pressure around
29.7 inches approaches from the southwest, allowing winds to 
shift east northeast. will need to watch for gale force gusts 
later this week, particularly thursday, as the low pressure 
system approaches the lake.
