open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
246 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. 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.

246 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. 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.
