open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
856 am cdt sun apr 26 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...

generally easterly breezes expected this morning as high pressure
around 30.2 inches shifts eastward into southeast ontario. 
low pressure around 29.4 inches then moves from northeast kansas 
early monday to lake superior by early tuesday morning, bringing
winds around to southeasterly monday into monday night.
southeasterly winds will increase and become gusty around 30 kt
monday afternoon into monday night. a few gales are possible
during this time frame, although the cooler lake temperatures may
limit the risk for gales. breezy west winds will then develop 
behind the departing low by midday tuesday. lighter winds should 
then occur into the rest of next week as high pressure builds in.
