open lake forecast for lake michigan
national weather service milwaukee/sullivan wi
259 pm cst fri jan 23 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 of 30.9 inches will build through the great lakes
region tonight into saturday, allowing northwesterly winds to
slowly diminish this evening and become light and variable
overnight. a heavy freezing spray warning remains in effect
through late tonight for continued elevated wave conditions and
frigid temperatures. high pressure will slide eastward into sunday
morning, with low pressure of 29.8 inches developing in the lower
mississippi valley. this will allow winds to shift northeasterly,
then back to northwesterly into sunday night as low pressure
exits. winds continue to back to westerly into monday as the low
lifts into the northeast.

high pressure around 30.7 inches builds into the lower
mississippi valley by tuesday, with an area of low pressure over
the hudson bay. expect southwest winds tuesday, then turning back
to northwest as the parent low's cold front moves through.
northwest winds continue through the end of the week. additional
freezing spray potential develops monday night through thursday.
occasionally heavy freezing spray is possible.
