open lake forecast for lake superior
national weather service marquette mi
401 pm edt tue jul 14 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... 

weak 30.0 inch trough moving over the lake this afternoon and 
evening gives way to 30.1 inch ridging, which persists until friday 
morning. expect the ridge to retreat east towards the st. lawrence 
seaway and to weaken with time on friday. a low pressure of at least 
29.8 inches could impact the upper great lakes this weekend, 
although uncertainty remains high on the track and strength of it.
