open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
220 am cst sat dec 20 2025

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...

30.2 inch high pressure currently centered over ohio will 
continue to drift east early this morning, while 29.3 inch low 
pressure continues to move east into ontario. the progression of 
the low and the high will result in increasing southerly winds 
across the open waters from predawn through late morning today. 
gusts will periodically exceed gale force, with a gale warning 
having gone into effect at 2 am cst early this morning. a brief 
decrease in gusts may occur from late morning into the early 
afternoon as a cold front approaches and begins to cross lake 
michigan. the passing boundary will result in a west-northwest 
wind shift across the waters. west-northwest gusts will then 
quickly increase in the wake of the passing front by late 
afternoon, when a return of widespread gales is anticipated across
the open waters. gales will continue into the predawn hours 
sunday, with the ongoing gale warning remaining in effect until 3 
am cst. snow and rain-snow mix will accompany the 
approaching/passing cold front this morning and afternoon. areas 
of moderate freezing spray are expected this evening as arctic air
settles in behind the departed front. pockets of heavy freezing 
spray are possible, though conditions aren't expected to be 
widespread enough to warrant headlines at this time. trends will 
continue to be monitored in the coming forecasts.

winds will steadily taper over the open waters sunday morning and 
afternoon as 30.4 inch high pressure settles into the western 
great lakes. said high will move east of lake michigan sunday 
night into monday as 29.8 inch low pressure builds in the 
northern great plains, resulting in a south to southwest wind 
shift. 25-30 knot gusts are possible during the day monday, though
gale potential is low at this time. trends will continue to be 
monitored. winds will shift out of the west-northwest and weaken 
tuesday through tuesday night as the next area of high pressure 
moves into the northern great plains.
