open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
903 pm cdt thu may 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...

high pressure of 30.1 inches over lower michigan will continue to
shift eastward tonight, with southerly winds developing on the 
back side of the high. these winds will increase on friday behind 
the departing high and low pressure of 29.1 inches moving from 
central manitoba into ontario. a few gale force gusts will be 
possible in northern portions of the lake tomorrow afternoon and 
evening, though this setup looks too borderline for a gale watch 
at this point. 

southerly winds will persist on saturday, while becoming lighter
as the low pulls away to the northeast. southerly winds will
then pick back up sunday into monday ahead of approaching low
pressure. gales are possible monday and tuesday. multiple rounds 
of showers and storms will be possible this weekend into early 
next week.
