open lake forecast for lake michigan

513 pm cst fri mar 6 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...

low pressure around 29.5 inches in the central great plains will 
continue to track northwards into the upper mississippi river 
valley by this evening. southwesterly winds will prevail ahead of 
this low through the evening along with widespread rain and 
embedded thunderstorms will accompany the approaching low today. 
light to modest winds and milder temps will also create conditions
favorable for marine fog to develop at times through this evening
into saturday morning. thus a marine dense fog advisory is in 
effect for periodic drops in visibilities to less than 1 nm at 
times. then the low will move near or just north of lake michigan 
tonight into saturday morning and drag a cold front across the 
upper great lakes into saturday morning. will see breezy west to 
northwesterly winds behind the front and usher out the marine fog 
by late saturday morning. westerly winds will prevail through 
saturday night before increasing and turning more southwesterly 
for sunday into monday as a series of two low pressure systems 
develop and track north of lake michigan through this time frame.
cannot rule out a brief potential for gales sunday and monday for
the northern third of the open waters of lake michigan.
