open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
305 am cdt thu mar 19 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 29.9 inches will advance toward southern 
hudson bay through daybreak as high pressure around 30.1 inches 
builds into wi from the northern great plains. thus anticipate 
that the current southwest winds will trend light and variable
through this morning. another low pressure around 29.7 inches will
develop in the canadian great plains this afternoon, allowing 
winds to turn east-southeasterly across lake michigan. winds will
increase and veer south to southwesterly across the waters 
tonight as the low pressure progresses over or just north of the 
northern half of lake michigan. some rain or snow is possible over
northern lake michigan during the low's passage, with wind gusts 
expected to remain below gale thresholds. winds will then turn 
west-northwesterly friday as a cold front moves across the 
waters.

winds will become light friday night through saturday morning as 
high pressure around 30.0 inches moves across lake michigan. 
increasing southerly winds are expected saturday afternoon as a 
cold front approaches from the north. the front is expected to 
cross lake michigan saturday night into sunday morning, bringing 
gusty northerly winds into monday morning. rain and snow showers 
will accompany the passing cold front. widespread gales are not 
anticipated at this time, though trends will be monitored over 
coming forecasts. winds will decrease monday night, ultimately 
turning southerly and increasing once again during the day on 
tuesday.
