open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
145 am cdt mon oct 12 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...

broad low pressure around 29.5 inches over the central plains to
minnesota will drive south-southwesterly winds into today. this 
low is expected to lift into minnesota and eventually central 
wisconsin by this evening. expecting scattered showers and 
isolated thunderstorms to develop tonight as the low approaches 
and crosses the open waters. winds shift to northwesterly on 
tuesday as an associated cold front crosses the lake and the low 
pressure exits east. the front may stall just south of the lake 
tuesday night, with a light northerly breeze across the lake and 
shower / thunderstorm potential towards the southern end of the 
lake. 

high pressure around 30.2 inches building into the northern plains
will keep winds northerly into wednesday, turning northeasterly
wednesday night and easterly into thursday as the high pressure
passes north of the lake and low pressure of 29.9 inches develops
near missouri / illinois. 

low pressure looks to cross lake michigan thursday night, with
strong high pressure descending from western canada into the
dakotas / nebraska into friday. the pressure gradient between
these two systems will drive strong northwest winds across the 
lake friday through friday night, with confidence increasing for a
period of sustained gales. depending on the central pressures of
the low, high & affiliated pressure gradient, a few gusts
approaching storm force could be possible. will be monitoring
trends for possible headlines over coming updates.
