open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
256 pm cdt thu oct 30 2025

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...

low pressure around 29.8 inches over southwestern ontario and low
pressure around 29.4 inches over the northeast u.s. will combine
to produce continued northwesterly winds throughout tonight and
friday. on friday, a cold front from the low in ontario will
progress northwest to southeast across the open waters, bringing
briefly gusty northwesterly winds. winds will diminish into
saturday as low pressure exits and high pressure around 30.2
inches builds into the central great plains and middle mississippi
valley. expect light and variable winds saturday night before
gusty southwesterly winds develop ahead of a low pressure system
moving west to east across far southern canada sunday into monday.
gales are possible during this time frame, especially in the
northern half of the lake. low pressure will drag a strong cold 
front through the lake on monday, shifting winds to northwesterly 
and producing additional gale potential through monday night.
