OPEN LAKE FORECAST for Lake Michigan
National Weather Service Milwaukee/Sullivan WI
902 AM CST Fri Nov 14 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...

Expect moderate southerly winds to build across Lake Michigan
today as a low pressure trough around 29.5 inches approaches from
the Northern Plains. Winds begin to shift to the southwest into
Saturday as the low strengthens to around 29.2 tracks as it
reaches the eastern side of Lake Superior Saturday afternoon.
This low will also drag a cold front across the region Saturday
with west to northwesterly winds increasing across Lake Michigan
Saturday night into Sunday. Winds gusts will approach gale force
during this timeframe, especially for northeastern nearshore zones
in the far northern third of the lake Saturday night into Sunday.
While potential for gales persist, still a bit of uncertainty on
exceeding 34 knots for extended period. Thus will to continue to
hold off on any gale headlines at this time. Winds then look to
diminish into the start of next week as high pressure builds into
the Upper Midwest.
