open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
243 pm cdt fri aug 14 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...

periods of storms are expected to cross the southern half of lake 
michigan through sunday as a front remains stalled south over 
illinois and indiana. low pressure of 29.7 inches over kansas will 
track to the northeast and east toward southern lake michigan 
tonight into saturday. this low should help to bump up winds and 
waves across the southern two thirds of lake michigan into saturday. 
beyond this system, a broad ridge of high pressure of 30.1 inches 
will push into the great lakes early next week before another 
potential front moves through the region midweek.
