open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
242 pm cdt sat apr 25 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 30.0 inches over the northern great lakes will
result in northerly winds of 10-20 knots continuing into this
evening. a few webcams are showing some fog under the low clouds 
in southern portions of the lake. patchy dense fog will be 
possible through late afternoon into early evening. short term
models are showing this fog potential decreasing over the next few
hours, so will hold off on a dense fog advisory for now. 

east to northeast winds of 10 to 15 knots are then expected to 
develop tonight 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 the iowa/missouri border 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 by later tuesday.

open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
242 pm cdt sat apr 25 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 30.0 inches over the northern great lakes will
result in northerly winds of 10-20 knots continuing into this
evening. a few webcams are showing some fog under the low clouds 
in southern portions of the lake. patchy dense fog will be 
possible through late afternoon into early evening. short term
models are showing this fog potential decreasing over the next few
hours, so will hold off on a dense fog advisory for now. 

east to northeast winds of 10 to 15 knots are then expected to 
develop tonight 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 the iowa/missouri border 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 by later tuesday.
