open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
925 am cdt mon mar 30 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...

a frontal zone will sharpen over lake michigan today, with north
to northeasterly flow over northern portions of the lake and
southerly flow further south. the boundary between these two wind
patterns may setup as far north as sheboygan wi to manistee mi 
this morning, but should then sag south to a milwaukee wi to 
whitehall mi line into this evening (approximately), with both
wind flows becoming stronger far north and far south of the
boundary. some 20 to 30 kt gusts may occur over the northern and
southern thirds of the lake this evening into tonight as the
boundary sharpens. rounds of showers and thunderstorms are
expected tonight into tuesday across the lake, with a few stronger
storms possible at times (particularly along and south of the
frontal boundary). large hail would be the primary threat with any
stronger storms. 

the boundary sags further south as a cold front tuesday 
afternoon, focusing lingering shower and thunderstorm over
southern lake mi before washing it out later tuesday. gusty north
winds build in behind the front tuesday evening into wednesday,
with a chance for winds to reach gale force (current expectation
is gusts to 30 kt but no sustained or frequent gales). 

30.7 inch high pressure will shift from ontario to quebec through
the late week time period as 29.7 inch low pressure approaches 
from the southwest, allowing winds to trend east-northeasterly. 
will need to watch for additional isolated gale potential thursday
into friday as low pressure passes near or over lake michigan.
