open lake forecast for lake superior
national weather service marquette mi
1000 pm est mon feb 9 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 over the lower 
great lakes and a 29.7 inch low over lake winnipeg. tonight through 
tomorrow afternoon, this low will slowly push just north of lake 
superior, dragging a 29.8 inch trough over the lake as it 
progresses. as the low shifts to the ontario/quebec line tomorrow 
night, high pressure of 30.3 inches builds over the northern plains. 
this high gradually settles over the great lakes by thursday 
morning, building to 30.4 inches. friday, the high moves to the 
southern portion of the great lakes while a 29.9 inch low moves 
across northern ontario. this weekend, high pressure resumes over 
the great lakes as a whole before another clipper low pressure moves 
across manitoba and ontario while a colorado low develops.
