open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
832 am cdt mon aug 24 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...

29.7 inch low pressure remains nearly stationary over western 
quebec this afternoon, resulting in continued breezy northwest 
winds across the open waters of lake michigan. the breezy 
conditions will continue through through the remainder of the 
afternoon as the low lingers over the same general vicinity. 
currently centered from western lake superior toward north-central
wisconsin, 30.1 inch high pressure will gradually work over lake 
michigan this evening, bringing decreasing winds. expect readings 
to become light and variable near or just after sunset.

light and variable winds will continue into tonight as high pressure 
lingers over the western great lakes. the high will shift east into 
ontario tomorrow, resulting in a south-southwest wind shift across 
the waters. 29.7 inch low pressure will approach from the 
northern great plains tomorrow night into wednesday, reinforcing 
the south-southwesterly wind pattern. the low will cross lake 
michigan during the second half of the day wednesday, bringing a 
breezy northwest wind shift. gales are not expected as this 
occurs. showers and thunderstorms will accompany the 
approaching/passing surface low tomorrow night into wednesday 
afternoon. widespread severe weather is unlikely in these storms, 
though an isolated stronger storm with hail and gusty winds can't 
be ruled out. the next area of 30.1 inch high pressure will 
gradually build toward lake michigan from the northern great 
plains wednesday night through friday, bringing slowly decreasing 
winds. shower and storm chances return this weekend. whether any 
storms will be severe remains uncertain, with trends being 
monitored through this week.
