OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
918 PM CDT Sun Jun 14 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...

Northwest winds will gradually diminish this evening, becoming
west to southwesterly over all of the lake late tonight, as a weak
wave of low pressure moves south across Ontario and high pressure
extends across the central portion of the country. Low pressure
is then expected to deepen to 29.5 inches over northern Wisconsin
on Tuesday, then move across northern Lake Michigan into the
early evening. This will bring breezy southerly winds to the lake
on Tuesday shifting west to northwest after the low passes.
Numerous showers and scattered thunderstorms are forecast over
central and southern Lake Michigan on Tuesday.

On Wednesday, low pressure around area 29.2 inches will move into
the Upper Mississippi River Valley from the Great Plains. This
will bring breezy southeasterly winds to central and southern
Lake Michigan Wednesday afternoon and evening, with the low to
then move across central Lake Michigan Wednesday night. As low
exits into Thursday morning, expect winds to become northwesterly
and remain gusty across all open waters into Thursday afternoon,
before gradually diminishing. Widespread rain and scattered
thunderstorms are forecast Wednesday and Wednesday night.
