open lake forecast for lake huron
national weather service detroit/pontiac mi
929 am edt sat jul 18 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...will get a brief break from canadian wildfire smoke as
southwestly flow pushes it northeast out of the area. a low
pressure system tracking through the northern lakes region today
will drop a cold front through the eastern lakes which will bring
some showers and thunderstorms this morning and afternoon. high
pressure will then build into the region for sunday.
