Open Lake Forecast for Lake Huron
National Weather Service Detroit/Pontiac MI
1000 PM EDT Thu Oct 16 2025

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...High pressure will wash out into the west Atlantic
through the end of the week while a low pressure system moves
from the northern Plains into west Ontario. This will strengthen
the pressure gradient over the Great Lakes, increasing wind
speeds through the afternoon and evening. Low pressure, 29.20
inches, will then rapidly develop and move over Michigan Sunday,
bringing increasing potential to see gales for a greater portion
of the region.
