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

30.6 inch high pressure is centered over southern ontario late 
this evening, resulting in generally light winds across the open 
waters of lake michigan. winds will trend southerly through the 
second half of the overnight hours as the high continues east and 
29.7 inch low pressure moves across northern manitoba. said low 
will move into the hudson bay monday afternoon, resulting in 
breezy winds across lake michigan. gusts between 25-30 knots are 
possible over the northern third of the open waters, though gales 
are not expected at this time. winds will subside monday night 
through tuesday as low pressure shifts into quebec and 30.5 inch 
high pressure builds into ontario, with light and variable winds 
continuing into tuesday evening.

winds will trend east-northeasterly across the open waters late 
tuesday night through wednesday as 29.9 inch low pressure 
develops in the southern great plains and shifts northeast toward 
the mississippi river. the low will approach and ultimately pass 
near or just south of the southern open waters wednesday night 
into thursday morning, with gales not expected at this time. 
periods of rain will accompany the approaching/passing low 
wednesday into thursday, with a few thunderstorms possible over 
southern lake michigan wednesday afternoon and evening. severe 
weather is not anticipated at this time.

another area of 29.6 inch low pressure will form in the central 
great plains thursday night, and is forecast to progress toward 
the upper mississippi river valley during the day on friday. the 
low's approach will bring increasing southerly winds to the open 
waters on friday, along with widespread areas of rain and embedded
thunderstorms. the low will move from the upper peninsula of 
michigan toward the southern hudson bay friday night through 
saturday, dragging a cold front across lake michigan in the 
process. additional rain is expected during the frontal passage. 
winds will veer southwest to westerly as the front passes. a few 
gales are possible, with more widespread gale potential depending 
on the still uncertain precise track & central pressure of the 
passing surface low. will continue to monitor trends in coming 
forecasts.
