open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
239 pm cst tue dec 23 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...

northwest winds this afternoon with turn more easterly tonight
and southeasterly into wednesday, as high pressure around 30.4 
inches swings through tonight. winds turn back northerly later
wednesday night as another high pressure system around 30.5
inches swings through south central canada. winds swing back 
easterly as the high pushes east through christmas day.
southeast winds expected thursday night/friday with a weak low
pressure system around 29.7 inches passes likely south of the
lake friday. light and variable winds behind the system.

the next best chance for gales is early next week sunday through
monday with increasing chances, with high higher end gales
possible as well. this will be a result of a weak low passing
through with strong high pressure impinging from the west
causing a strong pressure gradient and thus strong northwest
winds.
