open lake forecast for lake huron
national weather service detroit/pontiac mi
404 am edt sun sep 13 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...low pressure of 29.3 inches will continue to push
eastward over northern ontario as it drags a cold front across
the central great lakes this morning. west to northwest flow
increases fairly quickly this afternoon behind the front, with
sustained winds around 25 to 30 knots. high pressure quickly
builds into the region monday, allowing northwest winds to relax
in/around daybreak. attention then turns to the potential for
gales on lake huron from the south and southwest late monday
night through tuesday as low pressure of 29.2 inches tracks
across the canadian prairies and eventually up into the hudson
bay region through mid week.
