open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
947 pm cst wed nov 4 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...

low pressure around 29.4 inches in northern wisconsin and the u.p.
of michigan will slowly lift north across lake superior through
tonight and move just south of james bay by dawn on thursday. 
breezy southwest winds with gusts up to 30 knots will persist 
through tonight. 

as the low pressure continues northeast through ontario/quebec 
thursday, it will drag a cold front across lake michigan thursday 
afternoon/evening. southwest winds will briefly turn westerly as 
the cold front passes over the lake late thursday morning, before
increasing and shifting northerly through the afternoon and 
evening following the passage of the cold front. a gale warning is
in effect for all of lake michigan thursday afternoon into friday
evening. northwest to north gales are expected to develop across 
the northern third of the lake and spread south down the lake with
time during the gale warning period. it is possible that the far 
southern open water zones do not see gales until friday afternoon.

high pressure is then expected to build across the upper great 
lake region through the weekend bringing lighter northwesterly 
winds.
