open lake forecast for lake huron
national weather service detroit/pontiac mi
953 pm est sat jan 17 2026

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...several successive disturbances of varying magnitude
work through the central great lakes this weekend and into next
week. this results in elevated winds, waves, freezing spray, and
additional snowfall, especially once arctic air surges by monday.
gale watches are in effect for most waters monday.
