open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
859 pm cdt tue mar 31 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...

northerly winds become brisk into wednesday as a high pressure
around 30.5 inches builds over ontario. high pressure will
strengthen into the day wednesday to 30.6 inches as it pushes
toward eastern ontario with a bit of a front sliding down the lake
with northeastern winds behind it. 

breezy easterly winds are then expected wednesday night into 
thursday between high pressure of now 30.7 inches east of james 
bay in canada, and low pressure of 29.4 inches lifting from the 
central plains into wisconsin. gusts appear more likely to reach 
gale force over far northern lake michigan on thursday and thus a 
gale watch has been issued thursday morning through most of the
afternoon. the breezy easterly winds will shift southerly from 
south to north across the lake thursday afternoon into the evening
with the passage of a warm front, then followed by the cold front
with winds shifting westerly late thursday night. precipitation 
is expected wednesday night through thursday with a chance for
some ice toward far northern parts of the lake, particularly
thursday morning. then expect some storm chances primarily over 
the southern half of the lake thursday afternoon and evening as
the 29.5 inch low pushes through the northern lake thursday 
night.
