open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
258 am cdt fri jul 17 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...

wildfire smoke from northern mn and northwestern ontario continues 
across all open waters of lake michigan and will reduce visibility
to 1 nm or less at times. thus a marine dense smoke advisory 
continues today through this evening for all open waters.

lighter winds continue as high pressure around 30.1 inches in mid
michigan gradually exits east toward the new england states ahead
of an incoming low pressure around 29.7 inches tracking in from 
the northern plains. this low pressure will shift winds across 
lake michigan to the southwest today and continue to push across 
ontario tonight through saturday dragging a cold front across the
lake through saturday morning. northerly winds will develop 
behind this frontal passage through the day saturday along with 
high pressure around 30.0 inches. the high will then work its way 
across the upper great through the day sunday and departing to the
east overnight sunday while another deepening low tracks across 
ontario for the start of next week. expect more southerly wind for
monday before another, stronger cold front pushes through the 
region by tuesday.

additionally will see periodic shower and thunderstorm chances 
across the lake heading into the weekend through the start of next
week.
