open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
233 pm cst thu jan 15 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...

breezy southwesterly winds will continue to build over lake 
michigan through the evening ahead of an approaching cold front. 
front will push across lake michigan overnight with breezy 
westerly winds setting up into the weekend as low pressure around 
29.2 inches digs down from northern manitoba through western 
ontario before settling over lake superior/northern lake michigan 
by friday evening. the low pressure will meander around this area 
into saturday with westerly winds continuing across the lake. then
the low pressure will gradually weaken as it shifts east saturday
evening allowing winds to briefly weaken overnight into sunday as
high pressure around 30.4 inches slides south through the central
plains. 

winds are then expected to shift more southwesterly and increase 
for sunday as another low pressure deepens to around 29.4 inches 
as it tracks into the lake superior region sunday afternoon/evening.
the associated cold front will sweep across lake michigan as the 
low pressure quickly pushes east into monday. expecting stronger 
northwesterly winds to develop behind the departing low and cold 
front sunday night through monday. there will be a potential for 
gales during this timeframe and will monitor to see if this gale 
trend continues. otherwise, low pressure kicks east later monday 
with another high pressure building into the region for tuesday.

given the colder arctic airmass settling over the area and brisk 
winds, expect freezing spray concerns across lake michigan this 
weekend and continuing into the next week as well with even colder
temps.

.synopsis...

a 29.2 inch low over northern manitoba this afternoon drops south to 
western lake superior by friday morning, weakening to 29.4 inches. 
this low slowly meanders over upper michigan friday into saturday 
morning, further weakening to 29.8 inches saturday afternoon when it 
reaches just north of gregorian bay. meanwhile, a 30.4 inch high 
sets up over the plains. as the low remains relatively stationary 
and weakens to 29.9 inches through sunday, the high settles toward 
the southeast u.s., briefly extending 29.9 inch ridging over lake 
superior late saturday night. this quickly is replaced by a clipper 
low of at least 29.5 inches on sunday. the low continues to quebec 
on monday as it deepens to 29.5 inches while another high pressure 
of 30.5 inches drops south over the plains. ridging of at least 30.0 
inches looks to briefly return to the upper great lakes on tuesday.
