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

.synopsis...

southerly winds will increase tonight as low pressure around 
29.4 inches crosses northern minnesota into lake superior. the 
low will strengthen to 29.2 inches as it reaches lake huron 
saturday afternoon. gusty northwest winds will develop on the back
side of this low and along the associated cold front. winds gusts
will approach gale force saturday afternoon through sunday 
morning, especially for the northeastern portion of lake michigan.
the area east of the south mid lake buoy may also see a few gale 
force gusts. there is still lower confidence for gusts exceeding 
34 knots for extended period so we will to continue to hold off on
gale headlines at this time. winds will diminish early next week 
as high pressure of 30.1 inches builds into the upper midwest.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
919 pm cst fri nov 14 2025

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...

southerly winds will increase tonight as low pressure around 
29.4 inches crosses northern minnesota into lake superior. the 
low will strengthen to 29.2 inches as it reaches lake huron 
saturday afternoon. gusty northwest winds will develop on the back
side of this low and along the associated cold front. winds gusts
will approach gale force saturday afternoon through sunday 
morning, especially for the northeastern portion of lake michigan.
the area east of the south mid lake buoy may also see a few gale 
force gusts. there is still lower confidence for gusts exceeding 
34 knots for extended period so we will to continue to hold off on
gale headlines at this time. winds will diminish early next week 
as high pressure of 30.1 inches builds into the upper midwest.
