open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
229 am cdt wed oct 14 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...

north winds for most of the lake tonight between a departing 
low pressure over the eastern great lakes and an approaching 
high pressure around 30.3 inches. winds will increase to 10 to 
20 knots by the wednesday afternoon, especially across the 
southern half of lake michigan as the high moves through the
northern great lakes with a tighter pressure gradient to the
south. winds will then become easterly wednesday night into 
thursday as the high pressure shifts eastward, with the stronger
winds remaining over the southern half of the lake. then two 
areas of low pressure are progged to merge over the great lakes 
region into a single low pressure toward the end of the week. 
this low pressure looks to deepen to around 29.5 inches as it 
shifts into the eastern great lakes later thursday through 
friday. expect winds to increase and shift to the northwest on 
the backside of the low pressure and behind its associated cold 
front as a strong high pressure around 30.7 inches impinges on 
the departing low. there is increasing confidence in a period of
gales, with a few gusts potentially approaching storm force for
the end of the week into the weekend. a gale watch has been
issued for the open waters friday morning into friday night.

the texas panhandle. as the high shifts into western quebec thursday 
afternoon, the lows begin to converge over the upper midwest, 
consolidating into a 29.8 inch low over the southern michigan state 
lines thursday night. in its wake, a 30.9 inch high builds over 
wyoming, weakening to 30.6 inches friday as it expands over the 
plains while the low deepens to 29.5 inches over new england. the 
high slides south of the great lakes at 30.4 inches by saturday 
night as a 29.4 inch alberta clipper moves into saskatchewan. 
sunday, the high builds back to 30.5 inches over the delmarva
