open lake forecast for lake superior
national weather service marquette mi
1001 am edt wed jul 15 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... 

30.1 inch ridging persists over lake superior through friday while 
gradually shifting east towards the st. lawrence seaway. low 
pressure passing through the northern plains looks to traverse the 
great lakes at around 29.7 inches friday night into saturday, 
although uncertainty remains high on track and strength. 
nevertheless, weak 29.9 to 30.0 inch ridging does look to return to 
lake superior on sunday.
