open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
854 pm cdt sat jun 6 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...

high pressure of 29.9 inches builds into the upper great lakes
and strengthens to 30.1 inches overnight. warm and humid air will
linger over the relatively cool waters of lake michigan, with a
plume of marine fog over north-central portions of the lake slowly
sagging southwestward overnight. a marine dense fog advisory
remains in effect for the northern 2/3 of the lake until midday
sunday. 

light and variable winds (predominantly north to northeast)
continue throughout sunday. broad low pressure over the great
plains and high pressure over the northeastern conus will lead to
modest southeast winds over the lake late sunday night through
tuesday. 

occasional chances for showers and thunderstorms are in the 
forecast, particularly late monday through monday night.
additional chances later in the week.
