open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
245 pm cdt fri oct 9 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...

high pressure around 30.2 inches will continue to push east 
through this evening. will see winds become more southeasterly 
and then shift more southerly overnight as the high pressure 
shifts further east while low pressure around 29.2 inches develops
over the northern plains. expect winds to increase for saturday 
as lake michigan sits in between the two systems and has the 
potential to produce southerly gusts up to 30 knots through early 
sunday morning. while cannot rule out a few, brief gale force 
gusts across the northern portions of the lake saturday afternoon 
and evening, we are not anticipating any gale headlines at this 
time through the weekend. 

as the main low pressure weakens to around 29.6 inches as it 
lifts ontario into james bay region, expect it to drag a cold 
front across the upper great lakes later sunday into monday, 
easing southerly winds before shifting more westerly then 
northerly later monday into tuesday. could see another round of 
gusty sub-gale wind gusts overnight into tuesday across the region
behind the cold frontal passage, but will gradually ease through 
midweek as another high pressure around 30.2 inches builds across 
the upper great lakes region.
