open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
853 pm cst thu jan 29 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...

currently light and variable winds will increase and veer north 
to northeast tonight into friday. a convergence band in the center
of the lake will divide northeasterly winds from northerly winds
overnight, with all winds becoming northeasterly into friday
morning as the convergence band moves onshore into wisconsin and
illinois. strong high pressure of 30.9 inches over the northern 
plains friday will head south over the weekend, reaching the 
southern united states by sunday while weakening to 30.5 inches. 
breezy northerly winds are expected through saturday as this high 
passes by to the west. a period of moderate freezing spray is 
likely from later friday through saturday given the breezy 
conditions and lingering cold airmass. breezy southerly winds are 
then expected sunday behind the departing high and ahead of an 
approaching trough.
