open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
253 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. tonight behind departing low 
pressure, resulting in northerly winds of 10-20 knots tonight into
saturday. areas of fog may linger into this evening until the 
cooler and drier airmass fully moves in behind the low. 

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