open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
851 am cdt tue aug 11 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...

light winds will dominate throughout the morning, with a line of
severe thunderstorms expected to cross the southern third around
midday today. main hazards with these storms will be strong gusty
winds, but an isolated waterspout cannot be ruled out.

light winds are expected to then continue throughout the week,
with periodic shower and thunderstorm chances for southern 
portions of the lake as weak areas of low pressure follow along 
a stalled front over the lake. this front finally begins to sag 
southward through friday, allowing high pressure around 30.2 
inches to build down across the upper great lakes. as the high 
pressure pushes east this weekend, expect low pressure to develop
over the plains and track across the great lakes, bringing 
increasing southerly winds.
