open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
347 pm cdt sun apr 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...

winds will taper through tonight as 30.4 inch high pressure 
builds into the great plains. northwest winds will increase once 
more during the day monday as a small area of 30.0 inch low 
pressure develops over lake huron. a few gale force gusts are 
possible over the northern half of the open waters during the 
afternoon hours, but are expected to be isolated and brief enough 
to preclude the need for any headlines. trends will continue to be
monitored. winds will decrease monday night into tuesday as 30.5 
inch high pressure moves over and east of the open waters. areas 
of moderate freezing spray are possible over the northern half of 
the lake monday afternoon and evening.

29.6 inch low pressure will form over the northern great plains
and approach lake michigan tuesday night into wednesday, 
resulting in increasing southerly winds across the waters. winds 
will remain gusty into wednesday night as the low passes near or 
just north of lake superior. gale force gusts will be possible
with this system. winds will taper during the day thursday when 
30.4 inch high pressure is forecast to move from the northern 
great plains toward lake superior. showers and a few thunderstorms
are expected wednesday into thursday, with severe weather 
potential appearing low at this time.
