open lake forecast for lake huron
national weather service detroit/pontiac mi
940 pm edt wed may 27 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...high pressure, 30.30 inches, will expand across
northern ontario tonight and thursday. this will drive a little
cooler air across the region and cause an uptick in winds and
waves in the nearshore. the high will drift to the southern great
lakes thursday night into friday, sustaining dry conditions
across the region. a secondary high pressure system is forecast
to expand from hudson bay friday to lake huron saturday. this
will drive a secondary push of gusty northeast winds, likely
increasing winds and waves in the nearshore areas.
