open lake forecast for lake huron
national weather service detroit/pontiac mi
939 pm est wed dec 31 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...moderate northwesterly winds under an arctic airmass
result in areas of heavier freezing spray over the northern
portions of lake huron into thursday morning. the lingering upper
trough maintains these winds through friday. a weak clipper,
29.90 inches, crosses the region saturday offering light snow
chances but only minimal increases in wind strengths.
