for waters beyond five nautical miles off shore on lake huron

waves are the significant wave height - the average of the highest
1/3 of the wave spectrum. occasional wave height is the average of
the highest 1/10 of the wave spectrum.

.synopsis...low pressure, currently 29.30 inches, deepens as it
tracks east of georgian bay tonight. this draws a cold front
across the great lakes and ramps up northwest winds in excess of
30 knots with gusts to gales. gale warnings are in effect tonight

build in starting sunday night.

open lake forecast for lake michigan

231 pm cst sat nov 15 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...

brisk northwest winds are expected to continue into sunday. wind 
gusts around 30 knots are expected during this period, with a few 
gale force gusts possible in the northern third of the open 
waters, as well as along the eastern lakeshore areas. still do not
have high enough confidence for gusts exceeding gale force for 
extended period, thus will continue to hold off on gale headlines 
at this time. 

winds begin to ease sunday night through monday, as high pressure
around 30.1 inches builds into the upper midwest. another low 
pressure system around 29.8 inches is expected to track from the 
central plains to south of lake michigan through the middle of 
next week. this may result in increasing easterly winds.
