open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
223 pm cst sat feb 14 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...

light and variable winds continue over the lake today, turning
south to around 10 knots tonight in advance of a weak cold
front. winds turn northwest behind the front post dawn sunday
morning then go back to light and variable late sunday. low 
pressure around 29.6 inches tracks east across ontario canada 
monday, leading to a south breeze over the lake. winds turn 
north and decelerate behind the associated cold front monday 
night. 

strong low pressure develops over the northern plains on
tuesday, leading to accelerating east winds over the lake. gusty
east to southeasterly winds are expected tuesday night as the
system tracks eastward into minnesota / wisconsin, and may veer
southwestward over the southern half of the lake wednesday 
morning / afternoon as the low builds further east. gales will be 
possible tuesday night into wednesday morning.

forecast predictability drops dramatically from wednesday night
through thursday. the aforementioned low pressure may interact 
with a second area of low pressure tracking northeast from the 
central plains during this period, with periods of gusty winds /
elevated waves remaining likely. gusty northwest winds are then
looking likely thursday night into friday as both low pressure 
systems depart eastward. one or two periods of gales will be
possible through the latter half of the week.
