open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
923 am cdt wed jul 1 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 30.1 inches will remain to the southeast of 
the great lakes, while low pressure around 29.5 inches moves 
slowly east across central manitoba into james bay. breezy south 
to southwest winds will persist through thursday, with lighter 
winds thursday night into friday. 

chances for thunderstorms are forecast across the northern half 
of the lake the remainder of this morning through tonight. there 
are chances for thunderstorms across the southern two thirds of 
the lake thursday into friday evening, and across the southern 
half of the lake later friday night into sunday. strong to severe
storms may occur at times, though confidence remains low in 
timing of stronger storms.

patchy marine fog will be possible at times, primarily over the 
northern half of the lake as the warm and moist airmass moves 
over the lake.
