open lake forecast for lake michigan...updated
national weather service milwaukee/sullivan wi
847 am cst thu feb 12 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 30.3 inches remains over the lake through 
this morning, with high pressure progressing eastward this 
afternoon and allowing southwesterly winds to develop tonight into
friday. west-southwest winds will continue through saturday as 
29.6 inch low pressure forms over northern manitoba. low pressure 
will move east into the hudson bay saturday night through sunday 
morning, pulling a weak cold front across lake michigan in the 
process. winds will briefly shift out of the northwest sunday 
afternoon behind the front.

winds will trend light and variable sunday night, as another high
pressure around 30.1 inches builds across the lake. winds will 
shift south, then southwesterly monday as the high shifts east, 
with readings steadily increasing through tuesday as around 29.5 
inches low pressure forms over the northern great plains. low 
pressure will approach and cross the lake tuesday night through 
wednesday, resulting in a westerly wind shift by wednesday 
afternoon. a few gales are possible tuesday night through 
wednesday morning, though how widespread they would be remains 
uncertain.
