open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
329 am cdt wed apr 1 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...

brisk north to northeast winds are expected today as high 
pressure around 30.7 inches builds over ontario. breezy easterly 
winds are then expected tonight into thursday between the high 
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 continues for 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 
freezing rain 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.
