open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
938 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 today between a departing low 
pressure over the eastern great lakes and an incoming high 
pressure around 30.3 inches. winds will gradually increase to 10 
to 20 knots this afternoon, especially across the southern half 
of lake michigan as the high pressure moves through the northern 
great lakes with a tighter pressure gradient to the south. winds 
will then become easterly overnight 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.
