open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
945 pm cdt fri apr 24 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 around 30.0 inches will build into northern 
wisconsin and the western u.p. through tonight behind departing 
low pressure, resulting in northerly winds of 10-20 knots tonight 
into saturday. areas of fog will linger overnight, as the drier
air mass has been a bit slower to arrive, but fog is expected to
ease after daybreak saturday.

east to northeast winds 10 to 15 knots are expected to develop 
saturday night into sunday as the high shifts eastward ahead of an
approaching low pressure system. the 29.4 inch low is expected to
lift from around northwest minnesota early monday to lake 
superior by early tuesday morning. winds will increase monday into
monday night out of the south to southeast ahead of this low. the
cooler lake temps should dampen the threat for gales across the 
lake, but a few severe storms may occur over the southern end of
the lake monday night. 

breezy west to northwest winds will then develop behind the departing
low on tuesday.
