open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
243 pm cdt mon sep 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...

southerly winds continue to pick up this afternoon and evening 
along with building waves across lake michigan as the departing 
high pressure around 30.3 inches moves up the st. lawrence river 
valley while low pressure around 29.3 inches tracks across 
southern manitoba and into ontario. as a result expect wind gusts 
of 25-40 kt across the lake overnight into tuesday morning. gales 
are expected across the all open waters thus a gale warning will 
go into effect this evening/tonight. will then see winds ease from
south to north through early tuesday morning and gale warning 
will drop for the southern two-thirds after daybreak, while gales 
linger longer into early tuesday afternoon for the northern third.
then as the cold front slides across the lake during the day 
tuesday, more northerly winds and high pressure around 30.4 inches
will fill in behind it for tuesday evening into wednesday. winds 
remain north-northeasterly through the end of the week, but 
southerly winds return friday ahead of another system progged to 
work its way across the region through the weekend.
