.synopsis...

lake superior is currently between a 30.4 inch high over new england 
and a 29.4 inch low elongated from the red river valley of the north 
to wyoming. as the high is kicked east by the remnants of hurricane 
isaias on sunday, the aforementioned low splits and weakens into a 
pair of 29.7 inch lows, one that remains in the central plains and 
another that moves across northern ontario. this will drag a 29.8 
inch low across lake superior into monday morning as 30.3 inch high 
pressure expands across the ontario and manitoba shores of hudson 
bay. by monday night, the high will weaken to 30.2 inches over 
quebec as the plains low moves into the upper great lakes region at 
29.7 inches. as the low escapes to new england tuesday into 
wednesday morning, a new 30.2 inch high forms over the dakotas, 
moving over lake superior at 30.3 inches wednesday night. thursday, 
the high shifts to the eastern great lakes as a 29.8 inch alberta

open lake forecast for lake superior
national weather service marquette mi
401 pm edt sat oct 10 2026

for waters beyond 5 nautical miles of shore on lake superior.

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...

lake superior is currently between a 30.4 inch high over new england 
and a 29.4 inch low elongated from the red river valley of the north 
to wyoming. as the high is kicked east by the remnants of hurricane 
isaias on sunday, the aforementioned low splits and weakens into a 
pair of 29.7 inch lows, one that remains in the central plains and 
another that moves across northern ontario. this will drag a 29.8 
inch low across lake superior into monday morning as 30.3 inch high 
pressure expands across the ontario and manitoba shores of hudson 
bay. by monday night, the high will weaken to 30.2 inches over 
quebec as the plains low moves into the upper great lakes region at 
29.7 inches. as the low escapes to new england tuesday into 
wednesday morning, a new 30.2 inch high forms over the dakotas, 
moving over lake superior at 30.3 inches wednesday night. thursday, 
the high shifts to the eastern great lakes as a 29.8 inch alberta 
clipper moves over lake winnipeg.
