open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
242 pm cst sun jan 25 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...

elevated waves and cold temperatures will support moderate to 
heavy freezing spray tonight through tuesday afternoon, with a 
heavy freezing spray warning remaining in effect between 6 pm cst 
this evening and 6 pm cst tuesday.

low pressure of 29.5 inches will move from the appalachian 
mountains into the northeastern united states tonight as 30.7 inch 
high pressure builds further into the central and southern great 
plains. progression of the two features will maintain breezy 
northwest winds over the open waters, with additional periods of 
25-30 knot gusts possible into monday morning across the southern 
half of the lake. 30.5 inch high pressure will build into the 
ohio river valley monday afternoon and night as 29.8 inch low 
pressure attempts to form over lake superior, resulting in a west-
southwest wind shift across lake michigan. winds will become 
gusty at times monday night into tuesday morning, when a few gales
are possible over the southern third of the open waters. while 
gales are not expected to be widespread at this time, trends will
continue to be monitored for potential headlines in coming 
forecasts.

winds will trend west-northwesterly tuesday afternoon and night as 
30.4 inch high pressure builds into the northern great plains. 
winds will gradually taper wednesday through thursday as said area
of high pressure moves into the upper mississippi river valley.

open lake forecast for lake superior
national weather service marquette mi
400 pm est sun jan 25 2026

for waters beyond 5 nautical miles of shore on lake superior.

waves are the significant wave height - the average of the
highest 1/3 of the wave spectrum. occasional wave height is the
average of the highest 1/10 of the wave spectrum.

.synopsis...

remnant 30.3 inch ridging over lake superior this afternoon 
gradually weakens to 30.1 inches through monday morning as a 30.7 
inch high lifts through the saint lawrence seaway, while another 
30.8 inch high drops south through the northern plains. a 29.8 inch 
low from manitoba deepens to 29.6 inches as it crosses the lake 
monday night into tuesday. a much weaker low grazes the northeast 
portion of the lake at 30.1 inches tuesday night into wednesday. 
strong high pressure descending from the canadian prairies late this 
week brings ridging of around 30.6 inches back over lake superior by 
friday, with ridging looking to persist into next weekend.
