OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
908 AM CDT Fri Jun 5 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...

Broad low pressure of 29.6 inches will slowly move across the
northern Great Lakes this afternoon and evening. Its weak and
decaying cold front will then follow for Saturday afternoon. Thus
modest south winds today will shift west to southwest tonight and
Saturday morning, followed by light and variable winds Saturday
afternoon. Light northeast winds will then prevail Saturday night
and Sunday as high pressure around 30.0 inches builds across the
region. Looking ahead, the start of next week will bring an
additional low pressure system to develop over the Great Plains
and bring a return of southerly winds to the Upper Great Lakes.
