open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
304 am cst mon nov 3 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...

strong low pressure of 29.0 inches will move across southern 
hudson bay, with southwest to west gales expected to continue 
across lake michigan through around 12z. a gale warning for the
entire lake remains in effect until 6 am cst monday. this will
coincide with showers exiting the region as well as the front
pushes out today. with the frontal passage, however winds will
turn more west to northwest through the day today. with strong
pressure gradient remaining winds will remain breezy. while there
may be a break in the gales this morning, gales are now expected
to return late morning early afternoon through the afternoon for
the northern two-thirds of the lake and lingering longer further 
north. as such we have extended the gale warning for the northern
two-thirds through 3z perhaps lingering a tad longer in the far
northern portions of the lake.

west to northwest winds subside tonight. high pressure around 
30.4 inches will pass just south of the lake on tuesday, with 
light to modest west winds turning south over time as a low 
pressure system around 29.6 inches pushes across the lake tuesday
night. expect a period of breezy northwest winds behind this low
wednesday with gales possible.
