open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
853 pm cdt mon aug 10 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...

continue to see light and variable winds across lake michigan as 
a stationary front remains in place south of the lake. this 
pattern will continue through midweek with periodic shower and 
thunderstorm chances for southern portions of the lake as small 
areas of low pressure follow along the stalled front. the front 
finally begins to sag southward through the end of the week 
allowing high pressure around 30.2 inches to build down across the
upper great lakes through friday. then as the high pressure 
pushes east expect low pressure to develop over the plains and 
track across the great lakes through the weekend bringing 
increasing southerly winds.
