open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
842 am cst tue feb 17 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...

east to southeast winds will increase today into tonight as 
strong, compact low pressure of 29.1 inches approaches from the
dakotas. high-end, easterly gales are expected from midnight into
wednesday afternoon over the northern third of the lake, where a 
gale warning remains in effect. the warmer airmass over the chilly
lake waters should limit the mixing down of higher gusts 
elsewhere across the lake.

winds will ease later wednesday into thursday and become southerly
as that low occludes and weakens to 29.5 inches over northern
minnesota. winds will increase thursday night into friday night 
as another strong low pressure system around 29.2 inches tracks
from iowa into central wisconsin. that low will cross northern or
central lake michigan friday morning and gradually weaken through
saturday. gusty northerly winds are expected sunday into monday.
