open lake forecast for lake huron
national weather service detroit/pontiac mi
956 pm edt sun jun 14 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...breezy conditions return each afternoon early this
week, but dry weather should prevail through at least tuesday
morning. the arrival of a low pressure system and it's attendant
cold front lead to showers and thunderstorms beginning tuesday
afternoon for the central waterways. a brief break in activity
ensues wednesday, followed by a secondary stronger system
wednesday night into thursday. more intense convection is
possible with the wednesday night system.
