open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
858 pm cst mon feb 16 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 northerly winds this evening will gradually become easterly
overnight as high pressure of 30.1 inches moves in from the
northwest. east to southeast winds will then increase later 
tuesday into tuesday night, as strong low pressure around 29.2 
inches moves toward the region. easterly gales are possible later 
tuesday night into wednesday afternoon over the northern third of 
the lake, where a gale watch is in effect. the warmer airmass over
the chilly lake waters may limit the mixing down of higher gusts 
elsewhere across the lake.

after somewhat lighter winds later wednesday into thursday, winds
will likely increase thursday night into friday night, as another
strong low pressure system around 29.2 inches lifts northeast 
through the region.
