waves are the significant wave height - the average of the

.synopsis...

lake superior is currently between a 30.5 inch high offshore of new 
england and a 29.6 inch low stretched out from nebraska toward james 
bay. throughout today, the low splits and weakens into a pair of 
29.7 inch lows, one that remains in the central plains and another 
that moves eastward into quebec. this will drag a 29.8 inch low 
across lake superior tonight 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 toward new england as a 29.8 inch alberta clipper 
swings southeast through manitoba. the alberta clipper tracks over 
lake superior friday morning, followed closely by massive high 
pressure reaching from nunavut to texas.

open lake forecast for lake superior
national weather service marquette mi
1001 am edt sun oct 11 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 30.5 inch high offshore of new 
england and a 29.6 inch low stretched out from nebraska toward james 
bay. throughout today, the low splits and weakens into a pair of 
29.7 inch lows, one that remains in the central plains and another 
that moves eastward into quebec. this will drag a 29.8 inch low 
across lake superior tonight 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 toward new england as a 29.8 inch alberta clipper 
swings southeast through manitoba. the alberta clipper tracks over 
lake superior friday morning, followed closely by massive high 
pressure reaching from nunavut to texas.
