open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
844 pm cdt sun may 31 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...

widespread gales are not anticipated through the period across the 
open waters of lake michigan. 30.4 inch high pressure will remain
entrenched across the hudson bay through monday, resulting in 
generally north to northeasterly breezes. the center of the high 
will build south over lake michigan tuesday and tuesday night, 
leading to generally north-northeast winds over southern lake 
michigan and light westerlies further north. said high will 
gradually shift east on wednesday, allowing winds to trend 
southerly across the entirety of the lake. 29.7 inch low pressure
will shift from the canadian great plains into ontario wednesday 
night through thursday, resulting in increasing southwesterly 
winds across the waters. gusts up to 30 knots will be possible 
over the northern third of the lake during this time frame. 

the weather pattern will trend more active regionally thursday night 
into the weekend, with multiple chances for showers and storms 
returning to the open waters. strong storm potential remains 
uncertain at this time, with trends being monitored over coming 
forecasts.
