open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
228 am cdt tue may 5 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...

the cold front in association with low pressure around 29.0 inches  
moving east across james bay through today has largely pushed out
shifting winds to the northwest across the lake. these winds have
been weaker as well.

west to northwest winds then persist through the first half of 
today. winds will become light and variable by this afternoon and
through tonight, as a weak surface ridge passes over the lake. 
mainly light to modest winds are expected wednesday afternoon and 
night, before south to southwest winds return thursday into 
friday. gales are not currently forecast at this time.
