open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
253 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 overhead will continue to shift 
eastward this afternoon into 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. multiple rounds of showers and storms will be possible
this weekend into early next week.
