open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
244 am cdt tue sep 16 2025

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...

no major changes since the previous synopsis.

high pressure around 30.2 inches will remain over lake michigan
through wednesday as weak low pressure of 29.7 inches slowly lifts
from northern north dakota into the hudson bay today through
wednesday. expect light, generally southeasterly winds through
wednesday. a few areas of fog are possible each night through
wednesday as warm water and high pressure dominate the weather 
pattern. 

expecting winds to become easterly into thursday as low
pressure develops in the central plains, increasing and becoming
northeasterly thursday night into friday as low pressure 
approaches. a few thunderstorms are possible along a warm front
thursday night in the northern half of the open waters.
