open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
849 pm cst sun jan 18 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...

29.5 inch low pressure is centered over lake superior this 
evening, with an arctic cold front over western wisconsin. the
front will cross the waters tonight, bringing rapidly increasing
west-northwest winds. widespread gales are anticipated through
monday afternoon, with a gale warning in effect between 12 am cst
and 6 pm cst monday. winds will taper monday evening into early 
tuesday morning as 30.3 inch high pressure approaches from the 
northern great plains. winds will taper further and shift 
southwesterly on tuesday as the aforementioned area of high 
pressure crosses lake michigan. elevated waves and arriving arctic
air will lead to areas of heavy freezing spray from tonight 
through tuesday morning. a heavy freezing spray warning remains in
effect between 12 am cst monday and 12 pm cst tuesday given this 
potential.

west to southwest winds will continue through the day on wednesday 
as 29.8 inch low pressure passes near or just south of the open 
waters. gusts to 25 knots are possible. winds will increase 
further and shift out of the west-northwest wednesday night as 
another arctic cold front crosses lake michigan. gusts between 
25-30 knots are currently expected, with trends being monitored 
for possible gales in coming forecasts. arriving arctic air and 
elevated wave heights will support additional periods of moderate 
to potentially heavy freezing spray wednesday night through 
thursday morning, with trends being monitored for possible 
headlines in coming forecasts. winds will turn north-northwesterly
friday into saturday as 30.9 inch high pressure builds into the 
northern great plains. additional periods of moderate to perhaps 
heavy freezing spray are possible friday night through saturday 
night.
