open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
306 am cdt sun apr 19 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 30.4 inches tracking southeastward across
saskatchewan / manitoba will push a cold front across the lake
this morning, with southwest winds ahead of the front and 
northwest winds arriving behind it. some 20-30 kt gusts are 
expected behind the cold front for a brief period around or after 
noon today, particularly over far northern and southern portions 
of the lake. winds subside and veer north later today into tonight
as the aforementioned high pressure approaches. it crosses the 
lake late tonight into monday morning leading to light and 
variable winds. 

low pressure around 29.1 inches tracks along the southern edge of
hudson bay monday afternoon into tuesday, working with the
departing high pressure to drive breezy south winds over lake
michigan. our forecast calls for 30 kt gusts, but a few gales 
cannot be ruled out monday evening into early tuesday morning,
particularly over the northern third of the lake. 

a passing trough of low pressure leads to a period of variable
winds later tuesday. weak high pressure over ontario canada then
forces a weak backdoor cold front across the lake tuesday night
with light north to northeast winds continuing into wednesday
morning. 

winds should become southeast to south and increase later in the 
week as strong low pressure around 29.2 inches develops in the 
northern plains.
